Kinematics is the study of motion of a system of bodies without directly considering the forces or potential fields affecting the motion. In other words, kinematics examines how the momentum and energy are shared among interacting bodies.
The haze is a hazardous occurrence. It is a slight obscuration of the lower atmosphere, and the cause for its occurrence are the fine suspended particles. Thus we can conclude that the haze is actually caused by pollution of the air.
While the haze typically is a dry air phenomenon, it can also be a wet one if the conditions are right, though that happens relatively rarely. If the humidity in the air is 75-80% than the tiny aerosol particles of the dry haze start to act as condensation nuclei, resulting in a wet haze.
The time taken to play on 800 kJ energy of the candy bar is,
where E is the energy.
Substituting the known values,
As 1 minute is equal to 60 seconds,
Thus, the time taken to play tennis on the 800 kJ energy is 30.3 minutes.
(b). By doing the exercise, the process of digestion of food inside our body increases. Thus, the exercise does not helps us to burn the calories. But it helps us to diggest the heavy meal like candy bar easily.
The time taken to digest the canndy bar or to utilise its energy is large because it takes a lot of time to burn small amount of food and make it digest quickly.
