Weight = (mass) x (gravity)
On Earth ...
Weight = (1 kg) x (9.8 m/s^2)
Weight = 9.8 Newtons
The answer for this would be B!!
Nuclear power plants, wind farms, water farms, and geothermal heating
The minimum is 3 Newton, when the two forces act in opposite directions.
At the top of the height, the velocity is zero and acceleration is negative of acceleration due to gravity ( i.e
).
The time of the ball in air is 3.2 s, so ascending time is
.
Therefore from kinematic equation,

Substituting the values we get,
, Here v = 0 at top.
Now from equation,
, here h is the height .
So,
.
Thus, the ball reached at its maximum height of 12.48 m.
