Answer:
It remains constant
Explanation:
As we know that buoyant force on an object given as
Fb = ρ Vd g
ρ= Density of fluid
Vd=Volume displace by body
g=10 m/s²
Fb =buoyant force
So from above we can say that buoyant force does not depends on the depth. It only depends on the fluid density and volume displace by body.
So when rock gets deeper and deeper the buoyant force will remain constant.
It remains constant
Answer:
Option A
Explanation:
The correct answer is Option A.
At room temperature, the resistance is equal to 100 ohms.
When the temperature is reduced to 77 K from room temperature, change in the resistance is very less.
The temperature coefficient of the resistivity of most of the metal is small for the metals which are approximately equal 0.01 /K.
hence, Change is only slightly.
