How much power is required to lift a 2.0kg mass at a speed of 2.0m/s

Power, P = 39.2 watts

Explanation:

Given that,

Mass of an object, m = 2 kg

Speed of the object, v = 2 m/s

To find,

Power required to lift the object

Solution,

The work done divided by time taken is called power required to lift an object. Its expression is given by :

Since, W = F.d

And v = d/t

P = 39.2 watts

So, the power required to lift an object is 39.2 watts.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
