Answer:
1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.
Explanation:
Answer:
v = 21.52 m/s
Explanation:
Given that,
The distance covered by the car, d = 6200 km
Time taken by the car, t = 80 hours
We need to find the speed of the car. The speed of an object is given by total distance dividing total time.
So, the speed of the car is 21.52 m/s.
We use about 38 percent of Earth's land surface for agriculture
time taken by the object dropped = 2s
this time depends on the height of the plane from ground
it is given by
now the distance covered horizontally is given as 190 m
now the speed of the object is
now when plane is moving at same height but with double speed
so it will take same time to hit the ground again
so the time is given as
so it will take t = 2 s again to hit the ground
infiltration and evaporation
