B. The solar energy is responsible for the currents being made in the atmosphese and the hydrosphere. It creates a convection current in the planet that maintains the flow of the air and the water in it. That's why you experience changes in temperature on the air during daytime and night, as well as varying currents on the seaside depending on the time of the day/night.

Answer:
In the first law ,an object will not change its motion unless a force acts on it. In the second law force on an object is equal to its mass times its acceleration. In the third law ,when two objects interact , they apply forces to each other of equal magnitude and opposite direction
Answer:
Explanation:
height of the building h = 15 m
initial vertical velocity u = 0
v² = u² + 2 g h
u = 0 , final velocity after falling height h
h = 15
v² = 2 x 9.8 x 15
v = 17.14 m /s
. Time of fall be t
h = 1/2 g t²
15 = 1/2 x 9.8 x t²
t = 1.749 s
This time will be required for truck to come under the building .
speed = distance / time
distance = speed x time
= 22 x 1.749
38.5 m
Truck should be at a distance of 38.5 m . when the stuntman starts falling .
Answer:
itsgoing to be aroud 36 speed
Explanation:
bc if u think about it it make sence
