Answer:
μ = mg/kx
Explanation:
Since the bock does not slip, the frictional force equals the weight of the block. So, F = mg. Now, the frictional force, F = μN where μ = coefficient of static friction and N = Normal force.
Now, the normal force equals the spring force F' = kx where k = spring constant and x = compression of spring.
N = F' = kx
So, F = μN = μkx
μkx = mg
So, μ = mg/kx
If there's any point in a circuit where the current has a choice
of which branch to take, then you have a <em>parallel circuit</em>.
My guess is; The warmer ocean adds water vapor to the air mass.
I'm really sorry if I'm wrong
