Speed of any freely falling object is always same. Provided, both are left to fall from the same height. If you perform this experiment in a perfect vacuum or near vacuum laboratory, both of them will reach ground with same velocity this is because there is no resistance to their motion. This is always true no matter where you go and perform this experiment.
It can be easily proved from conservation of mechanical energy. Why conserving energy? because there are no forces acting on the freely falling objects other than conservative force(mg).
Answer:
lThe effect of the attraction of the earth on a bigger stone can be observed more than the effect of attraction of the earth on a smaller one. hence it is difficult to lift a large stone than the smaller one on the earth surface.
The correct answer is :
<span>D If the radiation were to leak out of the reactors, it could cause significant damage to living organisms.

In fact, the ionizing radiation that leaks out from a nuclear reactor is able to modify the DNA of the cells of living organisms, causing mutations and/or diseases like cancer.</span>
Answer:
93 V
Explanation:
use the expression for induced emf as
EMF = L dI/dt
L = 560 x 10⁻³
dI = 2.5 A
dt = 0.015 s = 15 x 10⁻³ s
EMF = L dI/dt
= 0.560 * 2.5/0.015
= 93.33 V
≅ 93 V
