Answer:

I can not see the image, so i will answer in a general way.

As you know, the sound behaves like a wave, this means that the sound needs some time to cover a given distance. An example of this motion can be seen when you drop a little stone in water, and you can see how the waves expand.

This means that the one who will hear the sound first, will be always the one that is closer to the source of the sound, in this case, the sound comes from the ball hitting the backboard, then the one who is closer to the backboard will hear the sound first.

Answer:

0.10 m/s

Explanation:

The graph appears to be linear, so the velocity is constant and is represented by the slope of the graph. The slope can be calculating by taking any two points and inputting them into the equation: \(\frac{y_2-y_1}{x_2-x_1}\) which is essentially rise/run. In this case the slope is really easy to calculate taking the two points of (0, 0) and (10, 1). In this case you can easily see the rise is 1 and the run is 10. So the slope is 1/10. So the average velocity of the object was 0.10 m/s or 1/10 m/s

P = F / A = force / area

F(force) = 1400 * .05 = 70 N

An object's mass, rather than its weight is used to indicate the amount of matter it contains because weight is defined as the amount of force due to an existing field (In most cases, gravitational field) that is experienced by the body. The weight of the same body can be different in different environments it's observed.

However, the mass of the body is the exact measure of the amount of matter contained in a body. Which is constant, regardless of the environment, or conditions the body is observed.

Hence, for real-world calculations and experimentation, the mass of the body is considered to represent the amount of matter it contains rather than its weight.

At the location marked by the red line, the total internal loading is -4 kN of shear force and 8 kNm of the moment.

The internal loading due to the support at the wall can be determined using the equation for the shear force (V) and the moment (M) at any point along the beam:

V = -wL/2 = -4*6/2 = -12 kN

M = 0 kNm

Next, we will determine the internal loading due to the uniform distributed load. The shear force (V) and the moment (M) at any point along the beam due to the uniform distributed load can be determined using the following equations:

V = wx = 42 = 8 kN

M = (wx)(x/2) = (42)(2/2) = 8 kNm

Finally, we will add the internal loading due to the support at the wall and the uniform distributed load to find the total internal loading at the location marked by the red line:

V_total = V_support + V_load = -12 + 8 = -4 kN

M_total = M_support + M_load = 0 + 8 = 8 kNm

Answer:

If an object has a fast velocity, the dots on a ticker tape diagram will be far apart.

The ammeter and voltmeter should be read simultaneously to determine the resistance of a circuit component because the resistance depends on the current passing through the component and the voltage drop across it. By measuring both the current and voltage, Ohm's law (V=IR) can be applied to calculate the resistance of the component.

The resistance of a circuit component represents how much it impedes the flow of current through it. According to Ohm's law, the voltage drop across a component is directly proportional to the current flowing through it, and the constant of proportionality is the resistance of the component. Therefore, to determine the resistance of a component, we need to know both the current passing through it and the voltage drop across it.

An ammeter is used to measure the current flowing through a circuit, while a voltmeter is used to measure the voltage difference between two points in the circuit. By reading both instruments simultaneously, we can use Ohm's law to calculate the resistance of the component being measured.

It is important to note that the readings must be taken simultaneously because the current and voltage can change over time, and any delay between taking the readings can result in inaccurate measurements. Therefore, it is necessary to read the ammeter and voltmeter at the same time to obtain an accurate measurement of the resistance of the component.

The efficiency of a bulb can be calculated as the ratio of the useful energy output (in this case, the light energy) to the total energy input. In this scenario, the useful energy output is 500 J - 350 J = 150 J, and the total energy input is 500 J. So, the efficiency can be calculated as:

Efficiency = (useful energy output) / (total energy input) = (150 J) / (500 J) = 0.3 or 30%.

This means that 30% of the energy input was converted into useful light energy, while 70% was converted into heat. This is the efficiency of the bulb.

Answer:

Explanation:

Momentum is is given by:

p=mv

Where:

p is momentum, m is mass in kg and v is velocity in ms−1

p=120kg×11.2 m/ s= 1344 kgms=1344kgm^−1

The skater moves at a 10 m/s speed. The right answer is A.

We must examine the forces operating on the skater in order to calculate their speed. The horizontal force applied to the ground creates the centripetal force, which is pointed in the direction of the circular path's center.

The centripetal force is calculated using the formula F = (mv2) / r, where m is the skater's mass, v is the speed, and r is the circle's radius.

We may convert the skater's horizontal force of 1125 N to the centripetal force as follows:

1125 N = (45 kg * v^2) / 4 m.

We rearrange the equation to find v:

1125 N * 4 m = 45 kg * v^2.

4500 N*m = 45 kg * v^2.

If you multiply both sides of the equation by 45 kg, you get:

100 N*m = v^2.

Taking the square root of both sides gives:

v = 10 m/s.

Therefore, the skater's speed is 10 m/s. The correct option is A.

In a J-K flip flop, when the inputs are set as J=5V and K=0V, the output q will toggle or change state after the next clock cycle. Therefore, the output q will change from 5V to 0V (or vice versa) after the next clock cycle.

To determine the output of a J-K flip-flop after the next clock cycle, we need to consider the inputs, the current state of the flip-flop, and how the flip-flop behaves based on its inputs and the clock signal.

In a J-K flip-flop, the J and K inputs determine the behavior of the flip-flop based on their logic levels. The clock signal determines when the inputs are considered and the output is updated.

Given that the initial output (Q) is 5V, and the inputs J=5V and K=0V, we need to determine the output after the next clock cycle.

Here are the rules for a positive-edge triggered J-K flip-flop:

If J=0 and K=0, the output remains unchanged.

If J=0 and K=1, the output is set to 0.

If J=1 and K=0, the output is set to 1.

If J=1 and K=1, the output toggles (flips) to its complemented state.

In this case, J=5V and K=0V. Since J is high (5V) and K is low (0V), the output will be set to 1 (Q=1) after the next clock cycle.

Therefore, after the next clock cycle, the output (Q) of the J-K flip-flop will be 1V.

Answer: False.Machine efficiency is a measure of how much work is produced by a machine compared to how much energy is required to operate the machine.

The ratio of useful output work divided by the total input work is known as machine efficiency. This number is frequently expressed as a percentage (100 x work output / work input).Example:

For example, if you lift a 50-pound weight 10 feet in the air using a pulley, the work done is 500 foot-pounds. However, if it took 600 foot-pounds of energy to lift the weight, the pulley system's efficiency would be calculated as follows: 500/600 = 0.83 or 83 percent.

The efficiency of a machine is always less than one, in general. It is defined as the ratio of output energy to input energy. Because of losses due to friction and other variables, the output energy is always less than the input energy. As a result, the efficiency of a machine is always less than one.Answer: False.

Plantation farming was indeed very labor-intensive, which encouraged the institution of slavery.

Plantations, particularly in the historical context of the Americas, relied heavily on agricultural production of cash crops such as tobacco, cotton, sugar, and coffee. These crops required significant manual labor for planting, cultivating, harvesting, and processing. Due to the large-scale operations and labor-intensive nature of plantation farming, plantation owners sought to maximize profits by acquiring a cheap and abundant workforce. This led to the establishment and expansion of slavery, as enslaved individuals were forcibly brought from Africa to work on plantations. The institution of slavery was deeply intertwined with the economic structure and profitability of plantation farming, making it an integral part of the system. The labor-intensive nature of plantation farming thus played a significant role in encouraging and perpetuating slavery.

The toy automobile receives a 4000 N/s impulse within the first 40 seconds.

Impulse is a physics term that refers to the change in momentum of an object over a period of time. Momentum is the product of an object's mass and velocity, and represents the amount of motion that the object has. Impulse is defined as the force applied to an object over a given time interval, and is calculated as the product of the force and the time interval: Impulse = force x time

When a force is applied to an object, it can cause a change in the object's momentum. The greater the force or the longer the force is applied, the greater the change in momentum will be. In other words, a large impulse can result from either a large force acting over a short period of time or a smaller force acting over a longer period of time. Impulse is an important concept in physics, particularly in the study of collisions and other interactions between objects. By understanding how impulse affects an object's momentum, physicists can predict the outcome of these interactions and design safer and more efficient technologies.
