Answer: Height should be 44.1 m.
Explanation:
Pressure exerted by stationary water stored at a height is,
P = ρgh
4.41 ×
= 1000× 10× h
solving we get,
h = 44.1 m
7200 grams is what equivalen to 7.s kilograms
Answer:
The applied force is greater than the frictional force.
Explanation:
the chair moves at <u>a constant speed</u><u> </u><u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>not</u><u> </u><u>A</u><u> </u><u>or</u><u> </u><u>C</u><u>.</u>
if there is no friction then the chair <u>would accelerate and it would not be at a constant speed</u><u>.</u>
hence, the only possible answer is B.
Answer:
- Waves with higher amplitude transfer HIGHER energy.
- Waves with higher frequency transfer HIGHER energy.
This rotation causes days. The relative position of us to the sun, and the Earth's rotation will cause the sun to appear to rise above the horizon and below, creating day and night.
