1. B. False, when light is reflected, the incident rays are bent and change direction.

2. B. become diffused. Light hitting a rough surface would most likely.

3. B. False. Plane mirrors create virtual images.

4. D. All of the choices are correct.

5. B. The illusion of water on top of hot asphalt on a summer day is mirage.

6. A. The mirror refracts light rays that pass through it outward and away from the optical axis is convex mirrors.

7. A. True. The bending ability of a substance is recorded on the index of refraction.

8. A. True.  Light travels at the same speed at all times.

<h3>What is refraction of light?</h3>

The refraction of light is change in speed and direction of light when it hits obstacle.

<h3>What is reflection is light?</h3>

Reflection of Light occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface.

<h3>Reflection of light can be diffused or Specular</h3>

Specular reflection is a type of surface reflectance often described as a mirror-like reflection of light from the surface.

Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle.

The acceleration due to gravity for any object, including 1 washer on the string, is always assumed to be m/s2. The mass of 3 wa
Pachacha [2.7K]

Answer:

The force will increase in proportion to the mass of the objects

Explanation:

The acceleration due to gravity is always the same. It is expressed in meters per second squared or m/s². The figure of 9.81 m/s² is an average value that was taken after calculating the acceleration under different surfaces. In fact, the acceleration differs depending on the shape of the part of the earth in relation to the earth's magnetic field and force.

Thus, if one washer was 20 kg, the acceleration being 9.81 m/s² the weight will be:

F = ma

  = 20 * 9.81\\= 196.2 N

If there are there washers, the weight will be:

F = 3 * 20 * 9.81

  = 588.6 N

KATRIN_1 [288]

Answer:

0.178 °C

Explanation:

Given:

The frictional force, F = 48 N

Number of rubs, n = 18

Distance covered per rub, d = 7.16 cm = 0.0716 m

Total distance covered in 18 rubs, D = 0.0716 × 18 = 1.288 m

mass of the tissues warmed, m = 0.1 kg

Now,

Work done, W = Force × Displacement

W = 48 × 1.288 = 61.8624 J

Now,

Work done is the change in heat

W = ΔQ = 61.8624 J

also,

ΔQ = mCΔT

where, C is the specific heat

for human tissue, C = 3470 J/kg°C

thus,

61.8624 J = 0.1 × 3470 × ΔT

or

ΔT = 0.178 °C

Hence, the change in temperature is 0.178 °C

A car of mass 900 kg is traveling at 20 m/s when the brakes are applied. The car then comes to a complete stop in 5 s. What is t
ollegr [7]

Answer:

A. 36,000 W

Explanation:

m = mass of the car = 900 kg

v_{o} = Initial speed of the car = 20 m/s

v_{f} = Final speed of the car = 0 m/s

W = Work done by the brakes on the car

Magnitude of work done on the car by the brakes is same as the change in kinetic energy of the car.hence

W = (0.5) m (v_{o}^{2} - v_{f}^{2})\\W = (0.5) (900) ((20)^{2} - (0)^{2})\\W = 180000 J

t = time taken by the car to come to stop = 5 s

P = Average power produced by the car

Average power produced by the car is given as

P = \frac{W}{t} =\frac{180000}{5} \\P = 36000 W
