The resistance of the silver block is given by

where

is the silver resistivity

is the length of the block

is the cross-sectional area of the block
If we plug the data into the equation, we find the resistance of the silver block:
Answer:
D). energy resulting from the attraction between two masses.
Explanation:
Answer:
V = 5 m³
Explanation:
The density of air, d = 1.2 kg/m³
Mass of the dry air, m = 6 kg
We need to find the volume o the gas. We know that, the density of an object is given by mass divided by its volume. So,

So, the volume of the dry air is 5 m³.
