The measuring of how light reflects off of mirrors made from different materials falls under the field of optics. Therefore, option (C) is correct.
What is optics?Optics can be described as the branch of physics that studies the behavior, and properties of light and its interactions with matter and the construction of instruments that detect it. Optics can be described as the behavior of visible, ultraviolet, and infrared light because the light is electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.
The most general is geometric optics which treats light as a collection of rays that travel in straight lines and bend as they pass through or reflect from surfaces.
Physical optics can be described as a more comprehensive model of light, which involves wave effects such as interference and diffraction and that cannot be considered in geometric optics.

Answer:
Yes because
Explanation:
Clouds get their shapes from the air that surrounds them. ... Since clouds are made up of millions of tiny pieces of water, when they are really high up in the sky where the air is very cold, the water droplets freeze into floating ice crystals. When we observe these clouds way up in the sky, they look like wispy strands

distance= 10*6.5
distance= 65meters
Hence the displacement is 65meters
Cellular respiration occurs in every cell of our bodies. Through this process, we obtain the energy we need for life. During cellular respiration, oxygen helps in breaking down sugar molecules into carbon dioxide and water molecules. Which reaction correctly represents the cellular respiration process?(1 point)
carbon dioxide + water → sugar + oxygen + energy
sugar + oxygen → carbon dioxide + water + energy
carbon dioxide + water + energy → sugar + oxygen
sugar + oxygen + energy → carbon dioxide + water
Answer:
B. sugar + oxygen → carbon dioxide + water + energy
Explanation:
Energy is that which sustains living organisms, so as to perform various activities. One of the processes by which living organisms produce energy is by respiration.
Respiration involves the breathing-in of oxygen and breathing-out of carbon dioxide as a waste. The oxygen helps in breaking down molecules of carbohydrates e.g sugar in the system of living organisms into energy, carbon dioxide and water.
This process is well represented by the equation in option B.
The reaction which correctly represents the cellular respiration process is sugar + oxygen → carbon dioxide + water + energy.

A freight train traveling with a velocity of −4.0 m/s begins backing into a train yard. If the train's average acceleration is −0.27 m/s^2 , what is the train's velocity after 17 s?
Answer:
−8.59 m/s.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = −4.0 m/s
Acceleration (a) = −0.27 m/s²
Time (t) = 17 s
Final velocity (v) =?
Acceleration is defined as the change of velocity with time. Mathematically, it is expressed as:
Acceleration = change of velocity / time
Acceleration = (final velocity – Initial velocity) / time
a = (v – u) / t
With the above formula, we can determine the velocity of the train after 17 s. This can be obtained as follow:
Initial velocity (u) = −4.0 m/s
Acceleration (a) = −0.27 m/s²
Time (t) = 17 s
Final velocity (v) =?
a = (v – u) / t
−0.27 = (v – –4 ) / 17
−0.27 = (v + 4 ) / 17
Cross multiply
−0.27 × 17 = v + 4
−4.59 = v + 4
Collect like terms
−4.59 – 4 = v
−8.59 = v
v = −8.59 m/s
Thus, the velocity of the train after 17 s is −8.59 m/s.

Answer:
For a longitudinal wave, such as a sound wave, amplitude is measured by the maximum displacement of a particle from its position of equilibrium. When the amplitude of a wave steadily decreases because its energy is being lost, it is said to be damped. So, a sound wave 's amplitude decreases as it moves through a medium.

Consult Multiple-Concept Example 5 for insight into solving this problem. A skier slides horizontally along the snow for a distance of 12.4 m before coming to rest. The coefficient of kinetic friction between the skier and the snow is 0.0368. Initially, how fast was the skier going
Answer:
The speed with which the skier was going is approximately 2.9906 m/s
Explanation:
The given parameters are;
The distance the skier slides before coming to rest, s = 12.4 m
The coefficient of friction between the skier and the snow, [tex]\mu _k[/tex] = 0.0368
Therefore, for conservation of energy, we have;
Initial kinetic energy = Work done by the kinetic friction force
Initial kinetic energy = 1/2·m·v²
The work done by the kinetic friction force = [tex]\mu _k[/tex]×m×g×s
Where;
m = The mass of the skier
v = The speed with which the skier was going
g = The acceleration due to gravity = 9.8 m/s²
s = The distance the skier slides before coming to rest = 12.4 m
[tex]\mu _k[/tex] = The kinematic friction = 0.0368
Therefore, for conservation of energy, we have;
1/2·m·v² = [tex]\mu _k[/tex]×m×g×s
1/2·v² = [tex]\mu _k[/tex]×g×s
v² = 2×[tex]\mu _k[/tex]×g×s = 2 × 0.0368 × 9.8 × 12.4 = 8.943872
v = √(8.943872) ≈ 2.99063070271 ≈ 2.9906 m/s
The speed with which the skier was going = v ≈ 2.9906 m/s.

It's 5 kilometers from my house to the gym. If I walk to the gym and back home how many meters have I traveled
Answer:
10 km
Explanation:
Distance is a measurement of the length of space between two points or objects. Distance is a scalar quantity, that is it has magnitude and no direction. The S.I unit of distance is meter, but other units are inches, kilometers, mile and so on.
Total distance traveled = distance from house to gym + distance from gym back to the house
Total distance traveled = 5 km + 5 km
Total distance traveled = 10 km

A 125kg man buy a 6kg watermelon, a 3kg cantaloupe, and 6kgs of potatoes, he walks home with his purchases in a large bag. His walking speed is 2.5m/s2 , what force is required for him to get home?
Answer:
350N
Explanation:
Given parameters:
Mass of the man = 125kg
Mass of the watermelon = 6kg
Mass of cantaloupe = 3kg
Mass of potatoes = 6kg
Acceleration = 2.5m/s²
Unknown:
Force required to get home = ?
Solution:
To find this force we use;
Force = mass x acceleration
mass = 125 + 6 + 3 + 6 = 140kg
So;
Net force = 140 x 2.5 = 350N
