Answer:
The Gravity gets stronger
Explanation:
Newtons laws of motion.
Answer:
a) 17.086m
b) 0.1671 m
Explanation:
Given data: speed of water through the hose = 1.81 m/s
through the nozzle = 18.3 m/s
We know that maximum height of an object with upward velocity v is given by,
a) H = v^2/2g
where H is the maximum height water emerges
= 18.3^2/(2×9.8) = 17.086 m answer
b) Again,
H = v^2/2g
= 1.81^2/(2×9.8) = 0.1671 m
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.
