Explanation:

Answer 2

Green light (520 nm) enters glass with n = 1.52, the wavelength of light that enters the glass is 520 nm.

To find the wavelength of light that enters the glass, we can use Snell's Law, which relates the angles and indices of refraction for light passing through a boundary between two mediums:

n₁ × sin(θ₁) = n₂ × sin(θ₂)

In this scenario, we can assume that the angle of incidence is zero degrees (the light is entering the glass perpendicular to the surface). Therefore, sin(θ₁) becomes sin(0) which is 0.

Using Snell's Law, we have:

n₁ × sin(θ₁) = n₂ × sin(θ₂)

1 × 0 = 1.52 × sin(θ₂)

The wavelength of light that enters the glass remains the same as the initial wavelength in air, which is 520 nm (nanometers).

Thus, the wavelength of light that enters the glass is 520 nm.

Suppose you needed to push a 1,500-N sofa up a frictionless ramp with a 30° angle. How much force would you have to apply to the sofa?Show your work below.

Answers

Answer:

1299N

Explanation:

GIven data

Weight W= 1500N

Angle Ф= 30°

The applied force up the frictionless ramp is gotten by applying the formula below

F= WcosФ

substitute

F=1500 cos 30

F = 1500*0.8660

F= 1299N

Hence the applied force is 1299N

Utility companies charge by the kilowatt-hour. The number of kilowatt-hours used equals the number of kilowatts multiplied by the number of hours an electrical device was used. How long would it take for a 50-watt fan to use 1 kilowatt-hour of electricity? (Hint: 50 watts = 0.05 kilowatts.)

Answers

Answer:

t = 3 minutes

Explanation:

Given that,

Power of fan, P = 50 W

Energy used, E = 1 kWh

We know that,

Energy = Power/time

As, 50 watts = 0.05 kilowatts

So,

[tex]t=\dfrac{P}{E}\\\\t=\dfrac{0.05\ kW}{1\ kWh}\\\\t=0.05\ h[/tex]

or

t = 3 min

So, the required time is equal to 3 minutes.

heena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation? v = one-third pi 24 squared (12). v = one-third p 12 squared (24). v = four-thirds pi 24 cubed. v = four-thirds pi 12 cubed.

Answers

Answer:

v = four-thirds pi 12 cubed.

Explanation:

A ball has a spherical shape. The volume of a spherical shape can be calculated using the following formula:

[tex]V = \frac{4}{3} \pi r^3[/tex]

where,

V = Volume of Ball = ?

d = diameter of the ball = length across the ball = 24 cm

r = radius of ball = d/2 = 24 cm/2 = 12 cm

Therefore,

[tex]V = \frac{4}{3}\pi (12)^3[/tex]

Hence, the correct answer is:

v = four-thirds pi 12 cubed.

Give your answer in Newtons, do not include the unit in your answer.

Answers

Answer:

F = 4117.64

Explanation:

First, we will calculate the acceleration of the hand, by using the third equation of motion:

[tex]2as = v_f^2 - v_i^2\\[/tex]

where,

a = acceleration = ?

s = distance covered = compression = 8.5 cm = 0.085 m

vf = final speed = 0 m/s

vi = iniial speed = 10 m/s

Therefore,

[tex]2a(0.085\ m) = (0\ m/s)^2-(10\ m/s)^2\\a = - 588.23\ m/s^2[/tex]

negative sign hows deceleration.

Now, we will calculate the force exerted by the hand:

[tex]F = ma = (7\ kg)(588.23\ m/s^2)\\[/tex]

F = 4117.64 N

3.Three resistors of 25.0Ω, 30.0Ω, and 40.0Ω are in a series circuit with a 6.0-volt battery. What is the current in the circuit?

please answer by steps

Answers

Answer:

Current = 0.063 Amperes

Explanation:

Let the three resistors be R1, R2, and R3 respectively.

Given the following data;

R1 = 25.0Ω,

R2 = 30.0Ω

R3 = 40.0Ω

Voltage = 6 Volts

First of all, we would determine the equivalent or total resistance;

Total resistance (in series) = R1 + R2 + R3

Total resistance = 25.0Ω + 30.0Ω + 40.0Ω

Total resistance = 95 Ω

Next, we find the current flowing through the circuit;

Voltage = current * resistance

Substituting into the formula, we have;

6 = current * 95

Current = 6/95

Current = 0.063 Amperes

A uniform electric field, with a magnitude of 449 N/C, is directed parallel to the positive x-axis. If the potential at x= 4.59 m is 966 V, what is the potential at x= 1.61 m?

Answers

Answer:

2.334‬ kV

Explanation:

Since the electric field strength Ecosθ = -ΔV/Δx = -(V₂ - V₁)/(x₂ - x₁)

where V₁ = potential at x₁ = 966 V, x₁ = 4.59 m, V₂ = potential at x₂ = unknown, x₂ = 1.61 m and θ = angle between E and the x - axis.

Given that E = + 449 N/C and since it is directed parallel to the positive x - axis, θ = 0°

So,

Ecosθ = -ΔV/Δx

Ecos0° = -ΔV/Δx

E = -ΔV/Δx

E = -(V₂ - V₁)/(x₂ - x₁)

making V₂ subject of the formula, we have

-E(x₂ - x₁) = V₂ - V₁

-E(x₂ - x₁) + V₁ = V₂

V₂ = V₁ - E(x₂ - x₁)

Substituting the values of the variables into the equation, we have

V₂ = V₁ - E(x₂ - x₁)

V₂ = 966 V - 449 N/C(1.61 m - 4.59 m)

V₂ = 966 V - 449 N/C(-2.98 m)

V₂ = 966 V + 1,338.02‬ Nm/C

V₂ = 966 V + 1,338.02‬ V

V₂ = ‭2,334.02‬ V

V₂ ≅ ‭2,334‬ V

V₂ = ‭2.334‬ kV

A 200kg bumper car moving 3 m/s collides head on with a 392kg bumper car moving 6m/s. After impact, the larger car continues traveling in the same direction with a velocity of 1.6 m/s . Determine the speed of the other car.

Answers

Answer:

the final speed of the smaller car is 5.624 m/s

Explanation:

Given;

mass of the small car, m₁ = 200 kg

initial velocity of the small car, u₁ = 3 m/s

mass of the larger car, m₂ = 392 kg

initial velocity of the larger car, u₂ = 6 m/s

final velocity of the larger car, v₂ = 1.6 m/s

let the direction of the larger car be positive

let the direction of the smaller car be negative

Apply the principle of conservation of linear momentum to determine the final speed of the smaller car.

m₁u₁ + m₂u₂ = m₁v₁  +  m₂v₂

200(-3)  +  392(6)  = 200v₁   +  392 x 1.6

-600 + 2352  = 200v₁    +  627.2

1752   =  200v₁     +   627.2

1752  -  627.2     =  200v₁

1124.8  = 200v₁

v₁  =  1124.8/200

v₁ = 5.624 m/s

Therefore, the final speed of the smaller car is 5.624 m/s

(C) Both its potential and kinetic energies will increase.
(B) Its potential energy will decrease; its kinetic energy will increase.
(D) Both its potential and kinetic energies will decrease.

Answers

Answer:

Explanation:

The answer is A. First of all, due to the First Law of Thermodynamics, energy cannot be created or destroyed, it only changes form. That being said, it is impossible for the PE and the KE to both increase or decrease at the same time. The second one starts decreasing, the other starts increasing at the exact same rate. PE exists or is at its highest when an object has the potential to fall to a point lower than it is, and it is at this point where Kinetic energy is the lowest. If this block is kicked UP a ramp, which is odd but there you have it, the potential energy increases as it gets higher off the ground. Because of gravity, and assuming that once the block is kicked, the foot that kicked it is no longer important to it (meaning it's not being pushed up, it's just kicked once and that's it) and it will slow down very quickly. KE exists where there is a great amount of velocity.

The answer is A.

Just like engines, they need a type of fuel. Hurricanes form over warm ocean waters near the equator. For hurricanes, their fuel is warm, moist air. When hurricanes form, the warm, moist air above the ocean rises upward from close to the surface of the water. Because the warm air rises, it results in less air under the surface of the water. This area with less air is known as an area with low pressure.Air from areas surrounding this low pressure space pushes in to the area. This fills the low pressure area. The new air in this space becomes warm and moist and also rises. As the air continues to rise, the air surrounding the space swirls in to take its place. This process of air swirling in to replace air that has risen continues. Eventually, the moisture in the air forms clouds.The wind and the clouds that form create a system. A system is a pattern of weather. The system of clouds and winds continues to spin and grow. The water evaporating from the ocean's warm surface acts as the fuel, which is what helps this spinning and growing.
