Answer:

Around 330 m/s

The speed of sound in air is 343 meters per second

The acceleration of the elevator in this scenario is: 12.5 m/s2

The acceleration of the elevator can be determined by using the equation a = F/m, where F is the force on the scale, and m is the mass of the man. In this case, the force on the scale is 826 N and the mass of the man is 66 kg. Therefore, the acceleration of the elevator is 826 N / 66 kg = 12.5 m/s2.

To further explain, an elevator is subject to two forces: the weight of the people and the weight of the elevator. As the elevator rises, the force of gravity increases and the force on the scale increases as well. This is why the man standing on the scale reads 826 N. Therefore, the acceleration of the elevator is equal to 12.5 m/s2.

It is important to note that the acceleration of an elevator can also be affected by its speed. If the elevator accelerates, the force on the scale increases, and the man's reading increases as well. Conversely, if the elevator decelerates, the force on the scale decreases, and the man's reading decreases.

The centripetal force required for a planet to revolve in a circular motion around the sun is provided by the sun's gravitational pull on the planet. The round motion of the planet is caused by the centripetal force, which is always pointed in the direction of the sun's center at every point of its course.

The force of gravity accelerates items as they descend to the ground. Velocity is a measure of the speed and direction of motion, and acceleration is a change in velocity. The longer an object is in free fall, the faster it descends towards the ground due to gravity.

A planet needs to accelerate towards the circle's centre in order to travel in a curved route. Centripetal acceleration, which is provided by the gravitational attraction of the sun and the planet, is what causes this.

Therefore, yes, change in direction is acceleration.

Answer:

The given statement in this question is true. Only liquid refrigerant should enter the metering device.

Answer:

The average velocity is equal to the instantaneous velocity

Explanation:

The average velocity, \(\overline v\), is given as follows;

\(\overline v = \dfrac{\Delta y}{\Delta t}\)

Where;

Δy = The change in displacement

Δt = The change in time

The instantaneous velocity is the derivative found of the position of the object's displacement with respect to time

Therefore, the instantaneous velocity, \(v_{inst}\) = The limit of the average velocity as the change in time becomes closer to zero

\(v_{inst} = \lim_{t \to 0} \left (\dfrac{\Delta y}{\Delta t} \right ) = \dfrac{dy}{dx}\)

When the velocity is constant, the displacement time graph is a straight line graph, and the slope of the displacement-time graph which is the same as the velocity is constant  and therefore, we have;

\(Slope \ of \ straight \ line \ graph = \dfrac{y_2 - y_1}{t_2 - t_1} = \dfrac{\Delta y}{\Delta t}= \dfrac{dy}{dx}\)

Therefore, for constant velocity, we have, \(\overline v\) = \(v_{inst}\) the average velocity is equal to the instantaneous velocity.

The PE will be converted to KE entirely (if the lowest point is ground level)

A circuit that minimizes resistance will be able to carry the maximum amount of current.

What is Current?

It is defined as the amount of electric charge passing through a given point in a circuit in unit time. The SI unit of electric current is the ampere (A), which is defined as one coulomb of electric charge per second. Electric current can be either direct current (DC), which flows in one direction only, or alternating current (AC), which changes direction periodically.

Based on the results of this activity, a circuit that would carry the maximum amount of electric current should have:

High voltage: A higher voltage will cause a greater potential difference and push more electrons through the circuit.

Thicker wire diameter: A thicker wire diameter will have lower resistance, allowing more current to flow through the wire.

Shorter wire length: A shorter wire length will have lower resistance, allowing more current to flow through the wire.

Lower wire temperature: A lower wire temperature will have lower resistance, allowing more current to flow through the wire.

Answer:

a=1m/s²

Explanation:

note that the moving body is accelerating from 10m/s to 15m/s, so in this case the initial velocity is 10mls, and the final velocity is 15m/s, and the body makes this increase in just 5seconds. so looking at what we've been given in the question, we can now calculate acceleration.

so our Data is;

V= 15m/s

U= 10m/s

t= 5m/s

a=?

we can find acceleration by using these two formulas;

1) V= U + at

15= 10+ a(5)

15=10+5a

make 5a the subject of the formula, and to make it the subject of the formula, we need to transpose 10m/s, and when we transpose it, it will

become a negative number because of crossing the equal sign

15-10=5a

5=5a

divide throughout by 5 to remain with a

5/5=5a/5

1=a

:. a=1m/s²

then the second formula is;

a= (V-U)/t

a=(15-10)/5

The potential drop across \(R_2\) is 7.455 V.  

The potential drop across  \(R_2\), we need to know the voltage drop across \(V_2\)  and the current flowing through  \(R_2\).

The voltage drop across \(R_1\) can be calculated using Ohm's law:

\(V_1\)  = I *  \(R_1\)

here \(V_1\) is the voltage drop across  \(R_1\), I is the current flowing through  \(R_1\), and \(V_2\) is voltage and the resistance of  \(R_1\).

The current flowing through  \(R_1\) is given, so we can calculate the voltage drop as follows:

\(V_1\) = (11.38 A) * (0.02899 m)

= 3.125 V

The current flowing through  \(R_2\) can be calculated using Ohm's law:

I * \(R_2\) = \(V_2\)  /  \(R_2\)

here \(V_2\)  is the voltage across  \(R_2\),  \(R_2\) is the resistance of  \(R_2\), and I is the current flowing through  \(R_2\).

We know that the potential difference between the ends of  \(R_2\) is 2.70 V, so we can calculate the current flowing through  \(R_2\) using the equation:

I = \(V_2\)  /  \(R_2\)

I = 2.70 V / 0.02899 m

= 92.28 A

Therefore, the potential drop across \(R_2\) is:

\(V_2\) = I *\(R_2\) *  \(R_2\)

= (2.70 V) * (0.02899 m)

= 7.455 V

Therefore, the potential drop across  \(R_2\) is 7.455 V.

Answer: Energy is conserved.

Explanation: Energy stored in spring = Potential energy gained by object at maximum height

a) The average frictional force from the tree trunk that stops the bullet is given by the formula F = (0.0078 kg * 575 m/s) / Δt, where Δt is the time it takes for the bullet to come to a stop.

b) The time elapsed between the moment the bullet enters the tree and the moment it stops moving is given by the formula Δt = (0.0078 kg * 575 m/s) / F, where F is the average frictional force.

a) To find the average frictional force from the tree trunk that stops the bullet, we can use the concept of impulse. The impulse is defined as the change in momentum of an object and is equal to the force applied multiplied by the time it acts.

The initial momentum of the bullet can be calculated using the formula:

p_initial = m * v_initial

where p_initial is the initial momentum, m is the mass of the bullet, and v_initial is the initial velocity of the bullet.

Mass of the bullet, m = 7.80 g

= 0.0078 kg

Initial velocity of the bullet, v_initial = 575 m/s

Substituting the values, we have:

p_initial = 0.0078 kg * 575 m/s

The final momentum of the bullet is zero since it comes to a stop.

The change in momentum is given by:

Δp = p_final - p_initial

Δp = 0 - (0.0078 kg * 575 m/s)

The average frictional force (F) can be calculated using the formula:

F = Δp / Δt

where Δt is the time it takes for the bullet to come to a stop.

Now we can calculate the average frictional force:

F = (0.0078 kg * 575 m/s) / Δt

b) To determine the time elapsed between the moment the bullet enters the tree and the moment it stops moving, we can rearrange the formula for average frictional force and solve for Δt:

Δt = (0.0078 kg * 575 m/s) / F

a) The average frictional force from the tree trunk that stops the bullet is given by the formula F = (0.0078 kg * 575 m/s) / Δt, where Δt is the time it takes for the bullet to come to a stop.

b) The time elapsed between the moment the bullet enters the tree and the moment it stops moving is given by the formula Δt = (0.0078 kg * 575 m/s) / F, where F is the average frictional force.

The spring constant of the spring is closest to 210 N/m.

First, let's calculate the potential energy stored in the spring:

PE = 1/2 k x^2

Therefore:

x = F_ext / k = 67 N / k

and:

\(PE = 1/2 k (67 N / k)^2 = 2244.5 J/k\)

Next, let's calculate the kinetic energy of the block at point b:

\(KE\_b = 1/2 m v2^2 = 0.5 * 0.8 kg * (1.9 m/s)^2 = 1.216 J\)

The work done by friction over the rough section is given by:

\(W\_f = f\_k * d\)

The frictional force is:

f_k = μ_k * m * g

Substituting the given values, we get:

\(f\_k = 0.39 * 0.8 kg * 9.81 m/s^2 = 3.06 N\)

The distance traveled over the rough section is:

\(d = h\_b - h\_c = 0.3 m - 0.1 m = 0.2 m\)

Therefore:

\(W\_f = 3.06 N * 0.2 m = 0.612 J\)

Finally, let's calculate the kinetic energy of the block at point c:

\(KE\_c = 1/2 m v3^2 = 0.5 * 0.8 kg * (1.4 m/s)^2 = 0.392 J\)

Using the principle of conservation of mechanical energy:

\(PE = KE\_b + KE\_c + W_f\)

Solving for k, we get:

\(k = 2 * (KE\_b + KE\_c + W_f) / (67 N / k)^2\)

Substituting the given values, we get:

\(k = 2 * (1.216 J + 0.392 J + 0.612 J) / (67 N / k)^2 = 210 N/m\)

(a) The angular acceleration of the grinding wheel as it came to rest is approximately -0.008 rad/s² (clockwise).

(b) The wheel made approximately 1000 revolutions during the time it was coming to rest.

(a) We can use the formula of rotational kinematics:

ω = ω₀ + αt

where ω is the final angular velocity, ω₀ is the initial angular velocity, α is the angular acceleration, and t is the time.

Given:

ω = 0 rad/s (final angular velocity)

ω₀ = 20.0 revolutions per second = 20.0 * 2π rad/s (initial angular velocity)

t = 50.0 s

Substituting the values into the formula, we have:

0 = 20.0 * 2π + α * 50.0

Solving for α, we get:

α ≈ -0.008 rad/s² (clockwise)

(b) To find the number of revolutions the wheel made during the time it was coming to rest, we can use the formula:

θ = ω₀t + 0.5αt²
