Answer:

Explanation:

Oftentimes when people hear that something has a low or high pH, they worry that it is dangerous. But this is not the case, pH alone cannot tell you if a substance is dangerous or not. Anyway, bases are typically considered more dangerous than acids! But what is pH? A substances pH is simply the concentration of hydrogen ions (H+) of the material when in solution (usually water). It is a numeric (logarithmic) scale used to specify how acidic or basic an aqueous solution is and an aqueous solution is just a solution where water is the solvent.  

A 40 kg crate is pulled at a constant velocity. The coefficient of kinetic friction is 0.5 and the crate moves 7 m . The amount of work done is 140 joule.

When an object is moved over a distance by an external force, at least a portion of that force must be applied in the direction of the displacement.

By multiplying the length of the path by the component of the force acting along the path, work can be calculated if the force is constant. The work W is equal to the force f times the distance d, or W = fd, to mathematically describe this idea.

The work is W = fd cos if the force is applied at an angle of to the displacement. Performing work on a body involves moving it in its entirety from one location to another as well as.

Therefore, A 40 kg crate is pulled at a constant velocity. The coefficient of kinetic friction is 0.5 and the crate moves 7 m . The amount of work done is 140 joule.

If the resistance remains constant and the voltage doubles, the power will increase by a factor of 4 (option E)

The following data were obtained from the question:

P = V² / R

Resistance is constant, we have

V₁² / P₁ = V₂² / P₂

V² / P = (2V)² / P₂

V² / P = 4V² / P₂

Cross multiply

V² × P₂ = P × 4V²

Divide both side by V²

P₂ = P × 4V² / V²

P₂ = P × 4

From the above, we can conclude that the power will increase by a factor of 4 (option E)

Work done on the jet by the catapult is 3.31x10⁷j

We are given that,

Thrust = F = 2.10105N

As a result, the work performed by the engines and the catapult will be equal to the kinetic energy of the jet at takeoff. then the formula can be used to determine the work the jet did.

Work done by the engines = Force x Distance

Work done by the engines,

(2.10 X 10⁵J)x 90m = 1.89 x 10⁷J

Total kinetic energy = 5.20x 10⁷J

The total kinetic energy minus the work produced by the engines is the amount of work the catapult does on the jet.

Therefore the

When you are working on a magnetic levitation experiment in a lab and beta radiation is emitted directly at you, passing through the magnets first, you are not safe because it was beta radiation and very dangerous.

The correct answer is option a.

Beta radation is a form of ionizing radiation that is made up of high-energy beta particles. Beta particles are high-energy, high-speed electrons or positrons that are emitted by certain radioactive isotopes. The emission of beta radiation from radioactive materials is referred to as beta decay.

Beta particles, unlike alpha particles, have a longer range and can penetrate through paper, skin, and other low-density materials but can be blocked by high-density materials.

Based on leah's informal experiment we can say, unbalanced forces from Joey pushing the car causes the car to change direction.

Forces that are opposite in direction and equal in size are termed as balanced forces. Since the car move across the table with constant speed, we can say acceleration is zero and net forece is also zero, until and unless Joey or Leah push the car. To change the direction and speed of the car, a net external force is required to be acted upon the car. A net external force by Joey is an unbalanced force which will change the direction and gives the speed to the car in opposite direction. Hence, it is an unbalanced force applied by the Joey that pushes the car in the other direction. Due to this force car starts to move back to Leah. Without, unbalanced force there will be no change in the direction of the car's motion or speed.

The ratio of the kinetic energy lost to the initial kinetic energy can be determined by comparing the final kinetic energy of the system to the initial kinetic energy of the projectile.

a) The angular speed of the system after the collision can be found using the principle of conservation of angular momentum. The final angular momentum of the system is given by the sum of the projectile's linear momentum and the rod's angular momentum:

L_final = (m * v_i * d) + (I_rod * ω_final)

where m is the mass of the projectile, v_i is its initial speed, d is the length of the rod, I_rod is the moment of inertia of the rod, and ω_final is the final angular speed of the system.

Since the rod is stationary, its initial angular momentum is zero. Therefore, the conservation of angular momentum can be expressed as:

0 = (m * v_i * d) + (I_rod * ω_final)

Rearranging the equation, we can solve for ω_final:

ω_final = -(m * v_i * d) / I_rod

Substituting the given values, we can calculate the angular speed in rad/s.

b) The ratio of the kinetic energy lost to the initial kinetic energy can be determined by comparing the final kinetic energy of the system to the initial kinetic energy of the projectile:

Kinetic Energy Lost / Initial Kinetic Energy = (Initial Kinetic Energy - Final Kinetic Energy) / Initial Kinetic Energy

The initial kinetic energy of the projectile is given by:

KE_initial = 0.5 * m * v_i^2

The final kinetic energy of the system is the sum of the kinetic energy of the projectile (which is now at rest) and the kinetic energy of the rod:

KE_final = 0.5 * m * 0^2 + 0.5 * I_rod * ω_final^2

Substituting the values, we can calculate the ratio of the kinetic energy lost to the initial kinetic energy.

According to the given statement , the potential difference V across the resistor R is 3105 V.

To find the potential difference V, we can use Ohm's Law and the formula for the potential difference across a capacitor.

First, let's calculate the current flowing through the circuit. We are given that I = 2.5 A.

Next, we can calculate the total resistance in the circuit using the formula R = R₁ + R₂. Given that R₁ = 40 Ω and R₂ = 1202 Ω, we can calculate the total resistance:

R = 40 Ω + 1202 Ω = 1242 Ω

Now, we can calculate the charge stored in the capacitor using the formula Q = C * V, where Q is the charge, C is the capacitance, and V is the potential difference across the capacitor. We are given that Q = 18 μC and C = 3 μF. Plugging these values into the formula, we can solve for V:

18 μC = 3 μF * V
V = 18 μC / 3 μF
V = 6 V

Finally, we can calculate the potential difference V across the resistor R. Using Ohm's Law, we can use the formula V = I * R:

V = 2.5 A * 1242 Ω
V = 3105 V

So, the potential difference V across the resistor R is 3105 V.

In conclusion, the potential difference V across the resistor R is 3105 V.

The time constant of the RC circuit is approximately 0.674 m s.

To determine the time constant (τ) of an RC circuit, we can use the formula:

τ = RC

Given that the discharge current decreases to 22.0% of its initial value in 1.50 m s, we can calculate the time constant as follows:

The percentage of the initial current remaining after time t is given by the equation:

I(t) =\(I_oe^{(-t/\tau)\)

Where:

I(t) = current at time t

I₀ = initial current

e = Euler's number (approximately 2.71828)

t = time

τ = time constant

We are given that the discharge current decreases to 22.0% of its initial value. Therefore, we can set up the following equation:

0.22 =\(e^{(-1.50/\tau)\)

To solve for τ, we can take the natural logarithm (ln) of both sides:

ln(0.22) = \(\frac{-1.50}{\tau}\)

Rearranging the equation to solve for τ:

τ = \(\frac{-1.50 }{ ln(0.22)}\)

Calculating this expression:

τ ≈ 0.674 m s

The maximum height that the ball will reach is 25 feet. when the ball will reach its maximum height after 1.25 seconds.

The maximum height that the ball will reach can be determined by finding the vertex of the parabola represented by the function

h(t) = 40t - 16t²

The x-coordinate of the vertex can be found using the formula

x = - b / (2a)

where:

a = coefficient of the t² term

b = coefficient of the t term.

Given

a = -16

b = 40

x = -40/(2×(-16))

= 1.25

This means that the ball will reach its maximum height after 1.25 seconds. We need to substitute this value of t into the function to determine the maximum height:

h(1.25) = 40 (1.25) - 16 (1.25)²

= 50 - 25
