Answer:

A. 290,400

Explanation:

The kinetic energy of a car is 290,400J.

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2.

ke = 1/2mv^2

By using the formula, we get

= 1/2 * 1200 * 22^2

= 600 * 484

= 290,400 J

Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.

The magnitude and direction of the acceleration for both the proton and the electron are 8.0 x 10^4 N/kg eastward.

To determine the magnitude and direction of the acceleration of the proton and the electron in the given scenario, we need to consider the forces acting on them.

1. Proton:

The proton has a positive charge, so it experiences a force in the opposite direction to the electric field. The force acting on the proton can be calculated using the equation:

F = q * E

where F is the force, q is the charge, and E is the electric field.

The magnitude of the force on the proton is given by:

|fp| = |q| * |E|

Given:

Charge of proton, q = +e (elementary charge)

Electric field, E = 8.0 x 10^4 N/C

Magnitude of force on the proton:

|fp| = |q| * |E| = e * 8.0 x 10^4 N/C = 8.0 x 10^4 N

According to Newton's second law, F = m * a, where m is the mass and a is the acceleration. Since the mass of the proton remains constant, we can conclude that the magnitude of the proton's acceleration (Ap) is equal to the magnitude of the force on the proton divided by its mass:

|Ap| = |fp| / Mp

2. Electron:

The electron has a negative charge, so it experiences a force in the same direction as the electric field. The force acting on the electron can be calculated using the same equation as above:

|Fe| = |q| * |E|

Given:

Charge of electron, q = -e (elementary charge)

Electric field, E = 8.0 x 10^4 N/C

Magnitude of force on the electron:

|Fe| = |q| * |E| = e * 8.0 x 10^4 N/C = 8.0 x 10^4 N

Similarly, the magnitude of the electron's acceleration (ae) is given by:

|ae| = |Fe| / me

where me is the mass of the electron.

The maximum possible acceleration of the truck if the rope does not break is 0.51 m/s².

To find the maximum possible acceleration of the truck if the rope does not break, we can use the formula for the tension in the rope:

T = m₁a + m₂a

Where T is the tension in the rope, m₁ is the mass of the truck, m₂ is the mass of the car, and a is the acceleration of the truck.

We are given the mass of the car as 1442 kg and the maximum tension that the rope can withstand as 2306 N. We can rearrange the formula to solve for the maximum acceleration a:

a = (T - m₂a) / (m₁ + m₂)

Substituting the given values, we get:

a = (2306 N - 1442 kg × a) / (m₁ + 1442 kg)

Simplifying the equation, we get:

a = 0.51 m/s²

It is important to note that neglecting friction may not be a realistic assumption in some scenarios, and frictional forces should be considered if they are significant.

Answer:

A) a = 73.304 rad/s²

B) Δθ = 3665.2 rad

Explanation:

A) From Newton's first equation of motion, we can say that;

a = (ω - ω_o)/t. We are given that the centrifuge spins at a maximum rate of 7000rpm.

Let's convert to rad/s = 7000 × 2π/60 = 733.04 rad/s

Thus change in angular velocity = (ω - ω_o) = 733.04 - 0 = 733.04 rad/s

We are given; t = 10 s

Thus;

a = 733.04/10

a = 73.304 rad/s²

B) From Newton's third equation of motion, we can say that;

ω² = ω_o² + 2aΔθ

Where Δθ is angular displacement

Making Δθ the subject;

Δθ = (ω² - ω_o²)/2a

At this point, ω = 0 rad/s while ω_o = 733.04 rad/s

Thus;

Δθ = (0² - 733.04²)/(2 × 73.304)

Δθ = -537347.6416/146.608

Δθ = - 3665.2 rad

We will take the absolute value.

Thus, Δθ = 3665.2 rad

The helium-neon lasers most commonly used in student physics laboratories have average power outputs of 0. 250 mw

Intensity of laser beam is 72.3W/m²

Given:

average power output = 0. 250 mw

To Find: intensity of laser beam

First of all, we need to find the area of the circular spot, which is given by:

A = πr^2

where r is the radius of the spot, which is half the diameter, therefore

r = d/2 = 2.10mm/2 = 1.05mm = 1.05 x 10^-3m

So, the area of the spot is

A = π(1.05 10^-3m)^2 = 3.46 10^-6m²

We know that the power output of the laser is

P = 0.250mW = 2.5.10^-4W

So the intensity of the laser beam is

I = P/A = 2.5^-10 W/3.46-10^-6m^2 = 72.3W/m²

So, intensity of laser beam is 72.3W/m²

Explanation:

The mass of a baseball is too large to exhibit wave-like behavior, making the wave nature of matter insignificant.

The wave nature of matter is not important for a baseball because the mass of a baseball is too large to exhibit wave-like behavior.

According to the de Broglie equation, the wavelength of an object is inversely proportional to its mass. Since a baseball has a large mass, its wavelength is incredibly small and insignificant.

Additionally, wave-like behavior is only observable on the atomic and subatomic level, where particles have incredibly small masses.

Therefore, for macroscopic objects like a baseball, classical mechanics is a more appropriate way to describe its motion, and the wave nature of matter can be ignored.

Answer:

If the wind speed increased, the plane's ground speed would be affected.

Explanation:

The ground speed of a plane is the speed at which it is traveling relative to the ground. Wind speed affects the plane's airspeed, which is the speed at which it is traveling relative to the air. If the wind speed increases, it can either help or hinder the plane's ground speed, depending on whether the wind is a headwind or a tailwind. A headwind can slow down the plane's ground speed, while a tailwind can increase it.

The equation that can be used to find the velocity (v⃗) of a satellite in a medium Earth orbit is v⃗ = √(G * mp / r).

The equation that can be used to find the velocity (v⃗) of a satellite placed into a medium Earth orbit is the formula for orbital velocity, which is derived from the gravitational force and centripetal force acting on the satellite. The equation is:

v⃗ = √(G * mp / r)

In this equation, G represents the universal gravitational constant, mp represents the mass of the planet (in this case, Earth) that the satellite is orbiting, and r represents the radius of the orbit. The orbital velocity is the speed at which the satellite must travel in order to maintain a stable orbit around the planet.

The equation is derived by equating the gravitational force between the satellite and the planet to the centripetal force required for the satellite to maintain a circular orbit. By solving for velocity, we can determine the speed at which the satellite needs to move to stay in orbit.

Answer: The average acceleration required to stop the monorail train is approximately -4.4 m/s².

The stopping time of the monorail train is approximately 10 seconds.

Explanation:

To find the average acceleration required to stop the monorail train, we can use the equation:

v²-u² = 2as

where:

- v  is the final velocity (0 m/s, as the train finally stops)

- u is the initial velocity (44 m/s) (given)

- a  is the average acceleration

- s is the distance covered (220 m) (given)

Substituting the acquired values:

→0² = 44² + 2a(220)

Simplifying the equation:

→0 = 1936 + 440a

Rearranging the equation:

→440a = -1936

→a = -1936÷440

→ a = -4.4 m/s² (approx.)

∴The average acceleration required to stop the monorail train is approximately -4.4 m/s².

To find the stopping time, we can use the equation:

v = u + at

where:

- v is the final velocity (0 m/s)

- u is the initial velocity (44 m/s)

- a is the average acceleration -4.4m/s²

- t is the stopping time (To Find)

Substituting the known values:

→0 = 44 + (-4.4)t

Simplifying the equation:

→ -4.4t = -44

→t = -44÷ (-4.4)

→ t = 10 sec (approx.)

∴The stopping time of the monorail train is approximately 10 seconds.

Explanation:

A 0.0780 kg lemming runs off a 5.36 m high cliff at 4.84 m/s. What is its potential energy (PE) when it lands

The potential energy PE, relative to the ground, will be zero, because the lemming is at the ground level.

HOWEVER, a much better question would be:

A 0.0780 kg lemming runs off a 5.36 m high cliff at 4.84 m/s. What is its kinetic energy (KE) when it lands?

Let’s review the 4 basic kinematic equations of motion for constant acceleration (this is a lesson – suggest you commit these to memory):

s = ut + ½at^2 …. (1)

v^2 = u^2 + 2as …. (2)

v = u + at …. (3)

s = (u + v)t/2 …. (4)

where s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.

In this case, u = 0, a = 9.81m/s^2, s = 5.36m

So we find v using equation (2)

v^2 = u^2 + 2as

v^2 = 0 + 2(9.81)(5.36) = 105.1632

So the kinetic energy resulting from the vertical drop is Ekv = ½mv^2

Ekv = ½(0.078)(105.16) = 4.101J

BUT we need to add in the kinetic energy resulting from the horizontal velocity, which did not change during the vertical drop.

Ekh = ½(0.078)(4.84^2) = 0.914J

So the total kinetic energy is Ek = Ekv + Ekh = 4.101 + 0.914 = 5.015J

The potential energy of the object with a mass of 0.0780 kg  moving from a height of 5.36 m is 4.09 J.

Potential energy of an object is generated by virtue of its position at a height from the ground. It is stored in the object when it is at rest, Whereas,  kinetic energy is generated by virtue of the motion of the body.  These energies are together called mechanical energy of the object.

When the object starts moving from rest, its potential energy starts to convert into kinetic energy and when it stops the reverse occurs . The potential energy of  a body is dependant on its mass and height by the equation:

p = mgh

Given that, mass of the object = 0.078 kg

height  h = 5.36 m

acceleration due to gravity g = 9.8 m/s²

then potential energy p = 0.078 × 9.8 m/s² ×5.36 m = 4.09 J

Therefore, the potential energy of the lemming is 4.09 J.
