Answer: The correct answer is "Reflection".
Explanation:
Reflection is the phenomenon in which the light ray gets reflected from the surface without getting transmit or absorb. It bounces back from the surface.
There are two laws of reflection.
(1) The angle of reflection is equal to the angle of incidence.
(2) The reflected ray, the incident ray and the normal lie in the same plane.
When you see your image on the surface of the water in a pond, the reflection phenomenon is at work.
Therefore, the correct answer is "Reflection phenomenon".
Answer:
The height of the building is 88.63 m.
Explanation:
Given;
initial component of vertical velocity, 
= 12 m/s sin 26° = 5.26 m/s
initial horizontal component of the velocity, 
= 12 m/s cos 26° =10.786 m/s
horizontal distance traveled by the rock, x = 40.4 m
time of flight is calculated as;
x = t
t = x /
t = 40.4 / 10.786
t = 3.75 s
Determine the final vertical velocity of the ball;
Determine the height of the rock;
Therefore, the height of the building is 88.63 m.
Answer:
In thermodynamics, heat is transferred energy that moves between substances or systems because of their temperature difference. According to the first law of thermodynamic and the law of energy conversion s a form of energy, heat is cannot be created or destroyed only moves from one form to other.
The stone gets heat energy from fire and moves this heat energy or thermal energy to water as it cools off and the water warms up. Heat moves or is transferred spontaneously from the hot stone into the cold water. Eventually, the stone and water have the same temperature and water becomes heated. At the time of heat flowing out of the stone into the water, the heat energy became less ordered, due to spreading out through both the stone and the water. This is a net increase in entropy which is the second law of entropy.
"Twice each second" means "2 per second". <em>Frequency = 2 Hz.</em>
<em>Period </em>= time for one bounce = <em>1 second</em>
Amplitude = distance between "not stretched" and "greatest stretch".
<em>Amplitude = 10 centimeters</em>
