The net force slowing down the car can be calculated using Newton's second law of motion. With a car mass of 1748.6 kg and a change in velocity from 21.4 m/s to 20 m/s over a time interval of 5.3 s, the net force is approximately 1329.43 N.

Newton's second law of motion states that the net force acting on an object is equal to the product of its mass and acceleration. In this case, the acceleration is given by the change in velocity divided by the time interval.

Given:

Mass of the car (m) = 1748.6 kg

Initial velocity (u) = 21.4 m/s

Final velocity (v) = 20 m/s

Time interval (t) = 5.3 s

First, calculate the change in velocity: \(Δv = v - u = 20 m/s - 21.4 m/s = -1.4 m/s.\)

Next, calculate the acceleration using the formula: \(a = Δv / t = -1.4 m/s / 5.3 s ≈ -0.2642 m/s^2.\)

Finally, calculate the net force using Newton's second law: \(F = m * a = 1748.6 kg * -0.2642 m/s^2 ≈ -1329.43 N\).

Therefore, the net force slowing down the car is approximately 1329.43 N. The negative sign indicates that the force is acting in the opposite direction of the car's motion.

The amperage represents the rate at which electric charge flows through a conductor.

What is amperage?

Amperage is a measure of electrical current, or the rate at which electrical charge flows through a circuit. It is measured in units of amps (A). Amperage is related to voltage and resistance in an electrical circuit, and can be calculated using Ohm's law. Amperage is important to consider when sizing electrical components and wiring for a circuit, as too much amperage can cause damage to the components.

The amperage, also known as current, represents the rate at which electric charge flows through a conductor. It is measured in amperes (A) and is a measure of the quantity of electric charge that passes through a given point in a circuit per unit of time. In other words, amperage is a measure of how many electrons are flowing through a wire at a given moment. A low amperage means that there is a small amount of electric charge flowing through the conductor. This could be because the resistance of the conductor is high, or because the voltage of the power source is low. A low voltage, on the other hand, means that there is a small potential difference between two points in a circuit, which means that the electric charge is not being pushed as hard and may not be flowing as quickly.

Therefore, it represents the rate at which electric charge flows through a conductor.

Your question is incomplete, most probably the complete question is:

Mike’s Cookie Company You and your roommate are preparing to start Mike’s Cookie Company in your on-campus apartment. The company will provide fresh cookies to starving students late at night. You need to evaluate the preliminary design for the company’s production process to figure out how many orders to accept and how effectively your time, and that of your room mate, will be utilized. BUSINESS CONCEPT Your idea is to bake fresh cookies to order, using any combination of ingredients that they buyer wants. The cookies will be ready for pickup at your apartment within an hour. Several factors will set you apart from competing products such as store-bought cookies. First, your cookies will be completely fresh. You will not bake any cookies before receiving the order; therefore, the buyer will be getting cookies that are literally hot out of the oven. Second, you will have a variety of ingredients available to add to the basic dough, including chocolate chips, M&M’s, chopped Heath bars, coconut, walnuts, and raisins. Buyers will telephone in their orders and specify which of these ingredients they want in their cookies. You guarantee completely fresh cookies. In short, you will have the freshest, most exotic cookies anywhere, available right on campus. THE PRODCUTION PROCESS Baking cookies is simple: mix all the ingredients in a food processor; spoon out the cookie dough onto a tray; put the cookies into the oven; bake them; take the tray of cookies out of the oven; let the cookies cool; and, finally, take the cookies off the tray and carefully pack them in a box. You and your roommate already own all the necessary capital equipment: one food processor, cookie trays, and spoons. Your apartment has a small oven that will hold one tray at a time. Your landlord pays for all the electricity. The variable costs, therefore, are merely the cost of the ingredients (estimated to be $0.60/dozen), the cost of the box in which the cookies are packed ($0.10 per box; each box holds a dozen cookies), and your time (what value do you place on your time?). A detailed examination of the production process, which specifies how long each of the steps will take, follows. The first step is to take an order, which your roommate has figured out how to do quickly and with 100 percent accuracy. (Actually, you and your roommate devised a method using the campus electronic mail system to accept orders and to inform customers when their orders will be ready for pickup. Because this runs automatically on your personal computer, it does not take any of your time.) Therefore, this step will be ignored in further analysis. You and your roommate have timed the necessary physical operations. The first physical production step is to wash out the mixing bowl from the previous batch, add all of the ingredients, and mix them in your food processor. The mixing bowls hold ingredients for up to 3 dozen cookies. You then dish up the cookies, one dozen at a time, onto a cookie tray. These activities take six minutes for the washing and mixing steps, regardless of how many cookies are being made in the batch.  The next step, performed by your roommate, is to put the cookies in the oven and set the thermostat and timer, which takes about one minute. The cookies bake for the next nine minutes. So total baking time is 10 minutes, during the first minute of which your roommate is busy setting the oven. Because the oven holds only one tray, a second dozen takes an additional 10 minutes to bake. Your roommate also performs the last steps of the process by first removing the cookies from the oven and putting them aside to cool for 5 minutes, then carefully packing them in a box and accepting payment. Removing the cookies from the oven takes only a negligible amount of time, but it must be done promptly. It takes two minutes to pack each dozen and about one minute to accept payment for the order. That is the process for producing cookies by the dozen in Mike’s Cookie Company.

What are the resources? Assuming the order size is 1 dozen, what is the capacity of each resource?

The velocity of the ball in m/s if the angular velocity of the ball about the elbow joint is 28.5 rad/s and the ball is 1.25 m from the elbow joint is 35.6 m/s.

The velocity of the ball can be calculated  in the following way:

We know that the angular velocity of the ball about the elbow joint is 28.5 rad/s and the ball is 1.25 m from the elbow joint.

The formula for the velocity of the ball is given as:

Velocity = (angular velocity) x (radius)

The radius of the ball is 1.25 m.

Substituting the values of angular velocity and radius in the above formula, we get:

Velocity = 28.5 rad/s x 1.25 m= 35.6 m/s.

Therefore, the velocity of the ball is 35.6 m/s.

a. The probability that a randomly selected soda can has a volume less than 12 fluid ounces is approximately 0.3085

b. The probability that the sample mean volume is less than 12 fluid ounces, when a sample of size n = 32 is taken, is approximately 0.0023

c. The distribution of the sample mean becomes narrower and more concentrated around the population mean. Consequently, the probability of obtaining a sample mean less than 12 fluid ounces decreases because the sample mean is less likely to deviate significantly from the population mean.

a) Let X be the volume of a randomly selected soda can. We are given that the mean (μ) is 12.01 fluid ounces and the standard deviation (σ) is 0.02 fluid ounces.

We need to calculate P(X < 12). To do this, we standardize the variable using the z-score formula:

z = (X - μ) / σ

Substituting the given values, we have:

z = (12 - 12.01) / 0.02

= -0.5

Now, we can use a standard normal distribution table or calculator to find the probability associated with the z-score of -0.5. From the table, we find that the probability is approximately 0.3085.

b) When a sample of size n = 32 soda cans is drawn randomly from the population, the mean volume of the sample (denoted by X-bar) follows a normal distribution with the same mean (μ = 12.01 fluid ounces) but a smaller standard deviation (σ-bar) given by:

σ-bar = σ / sqrt(n)

Substituting the values, we have:

σ-bar = \(0.02 / \sqrt{(32)\)

= 0.02 / 5.6569

≈ 0.00354

Now, we need to calculate P(X-bar < 12). Again, we standardize the variable using the z-score formula:

z = (X-bar - μ) / σ-bar

Substituting the given values, we have:

z = (12 - 12.01) / 0.00354

≈ -2.8249

Using the standard normal distribution table or calculator, we find that the probability associated with the z-score of -2.8249 is approximately 0.0023.

c) As larger and larger sample sizes are taken, the probability that the sample mean volume is less than 12 fluid ounces tends to decrease. This is because as the sample size increases, the sample mean becomes a better estimate of the population mean. The larger the sample size, the more reliable and representative the sample mean is of the true mean. Hence, the sample mean is more likely to be closer to the population mean.

Answer:

18.425 Joules

Explanation:

To figure this out we can simply use the W=Change in Kinetic Energy,

W = 1/2*.022*46^2-1/2*.022*21^2 (Note we can ignore the direction of the particles as we need to take the square of the velocity)

W=18.425 (By simplifying the expression)

Assuming that the wave passing through the pond causes the bug to move up and down, we can calculate the bug's maximum kinetic energy using the formula:

KE = 0.5 * m * v^2

where m is the mass of the bug and v is its maximum velocity.

Since the amplitude of the wave decreases from 7.0 cm to 4.5 cm, the maximum velocity of the bug will also decrease by the same factor, since the wave's energy is proportional to the square of its amplitude. Therefore, we can say that the bug's maximum velocity will decrease by a factor of 7.0/4.5 = 1.56.

Substituting this factor into the kinetic energy formula, we get:

KE_new = 0.5 * m * (v_old/1.56)^2

where KE_new is the bug's new maximum kinetic energy and v_old is its original maximum velocity.

Dividing KE_new by the bug's original maximum kinetic energy gives us the factor by which its kinetic energy has changed:

KE_new/KE_old = (0.5 * m * (v_old/1.56)^2)/(0.5 * m * v_old^2) = (v_old/1.56)^2/v_old^2 = 1/2.43

Therefore, the bug's maximum kinetic energy decreases by a factor of approximately 2.43 as the ripples decrease from 7.0 cm to 4.5 cm.

Periods indicate that a new period at a new principal energy level which is filled with electrons. Groups indicate that the elements share similar properties because their shells are filled with the same number of valence electons.

Explanation:

e see that starting at period 2 Li has a  +1 charge , He has +2 charge, B has +3 charge, C has the potential to have a +4 charge or -4 charge (because it can gain or loose electrons) and N has a -3 charge, etc. Groups however, have similar properties and every element in a 1A - 8A has the same number of valence electrons. All except the noble gases in which He only needs 2 electrons to be in a perfect state. This is its octet as it would be a completely different element if it had more than 2 electrons in its shell. An example of the groups sharing similar properties is if we were to look at group 1A. In group 1A we find H, Na, K, etc. These are all highly unstable elements when alone (not in a compound) and they are very reactive. If you were to put Na for instance in water, it would light up and you'd see a flame sitting on top of the water. A scientist could do that with the rest of the elements in the group and they would see this increasing in reactivity as you go down the periods. Francium isn't visible long enough to be able to see this happen though. It's more of that kind of element that scientists prove that it exists, but not a very common element to get to learn much about.

Explanation:

The expression for the energy stored (E) in a stretched wire of original length (L), cross-sectional area (A), tension (T), and Young's modulus (Y) is given by E = Y * e * ln(L) * A

The work done to stretch the wire can be calculated by integrating the force applied over the displacement. In this case, the force applied is the tension (T) in the wire, and the displacement is the change in length (ΔL) from the original length (L) to the stretched length (L + ΔL).

The tension in the wire is given by Hooke's law, which states that the tension is proportional to the extension of the wire:

T = Y * (ΔL / L)

where Y is the Young's modulus of the material of the wire.

Now, let's calculate the work done to stretch the wire:

dW = T * dL

Integrating this expression from L to L + ΔL:

W = ∫ T * dL = ∫ Y * (ΔL / L) * dL

W = Y * ΔL * ∫ (dL / L)

W = Y * ΔL * ln(L) + C

Here, C is the constant of integration. Since the energy stored in the wire is zero when it is unstretched (ΔL = 0), we can set C = 0.

Finally, the expression for the energy stored in the wire (E) is:

E = W = Y * ΔL * ln(L)

or, if we substitute the cross-sectional area (A) and strain (e) of the wire, where e = ΔL / L:

E = Y * e * ln(L) * A

Thus, the expression for the energy stored (E) in a stretched wire of original length (L), cross-sectional area (A), tension (T), and Young's modulus (Y) is given by:

E = Y * e * ln(L) * A

The force of the muscle contraction is approximately 1.962 Newtons.

To calculate the force of a muscle contraction given the vertical calibration, you need to know the weight of the object that is being lifted by the muscle. You can then use the weight and the vertical calibration to calculate the force of the muscle contraction.

In this example, the vertical calibration is 1 cm/100 g. This means that for every 1 cm of displacement, the weight of the object increases by 100 g. If the measurement is 2 cm, then the weight of the object has increased by:

Weight = 100 g/cm * 2 cm = 200 g

To convert the weight to force, we need to use the acceleration due to gravity, which is approximately 9.81 \(m/s^2\). We can convert the weight in grams to weight in Newtons using the following formula:

Force = Weight * 9.81 m/\(s^2\) * (1 kg / 1000 g)

where 1 kg / 1000 g is the conversion factor from grams to kilograms.

Plugging in the weight we calculated above, we get:

Force = 200 g * 9.81 m/\(s^2\) * (1 kg / 1000 g)

= 1.962 N

Therefore, the force of the muscle contraction is approximately 1.962 Newtons.

Direct variation suggests that two variables change in the same direction, when one variable decreases the other increases.

The boy initially walks 48 meters north and then turns around to walk 25 meters south, resulting in a net displacement of 23 meters north.

The boy's initial movement of 48 meters north is considered positive displacement along the north direction. However, after realizing his mistake, he changes his direction and walks 25 meters south, which is considered negative displacement along the south direction. The net displacement is obtained by subtracting the magnitude of the southward displacement from the magnitude of the northward displacement.

By subtracting 25 meters from 48 meters, we find that the net displacement is 23 meters north. This means that, despite walking in the wrong direction initially, the boy corrected his path and ended up 23 meters north of his starting point.
