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
Answer:
a
Explanation:
The type of specialized cell whose main function is to communicate between neurons is a(n) interneuron
Because the box keeps going straight at the same speed, while the seat under it speeds up, slows down, or changes direction.
The astronaut would go the opposite direction due to Newton’s third law of -10N, -10N, -9N, -9N
