Answer: Whenever the temperature is high, the air pressure is low.
Explanation:As the temperature rises, the air gets heated, expands, and becomes lighter. … As a result, the air pressure in such areas decreases.
Answer:
a) Mat swum 100 meters.
b)after 4 length , Mat's displacement is zero.
Explanation:
As given, Mat and David are training for the swimming team , and Length of 1 side of the pool is 25 meter.
As swimming pool will be a cube or a cuboid , so it has only 4 sides.
a)
1 length = 23 meter
⇒4 length = 4×25 = 100 meter
So, Mat swam 100 meters.
b)
As after swam 4 lengths of the pool, Mat reaches to its initial position i.e Mat come back to its starting point.
As Displacement is always measures from the starting point.
So, after 4 length , Mat's displacement is zero.
100J/20s= 5 joules per second
Or 5 watts
