Answer:
The distance covered by the body is, S = 800 m
Explanation:
Given data,
The initial velocity of the body, u = 30 m/s
The acceleration of the body, a = 10 m/s²
Let the time period of travel be, t = 10 s
Using the II equations of motion,
S = ut + ½ at²
Substituting the given values,
S = 30 x 10 + ½ x 10 x 10²
S = 800 m
Hence, the distance covered by the body is, S = 800 m
Answer:
c) wafers of crystalline silicon treated with metals that absorb solar radiation and generate electricity
Explanation:
Photovoltaic solar cells are used in solar panels. Most of the photovoltaic cells are made from crystalline silicon.
It has a property using which it converts the light (solar radiation) falling on it to electrical energy. This process occurs due to the photovoltaic effect.
It is a way generating energy without consuming fossil fuels. Thus it reduces the carbon emission and thus plays a major role in environment protection.
Answer:
The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.
