Answer:
Electric Current
Explanation:
An electric current is defined as the flow of electrons through the wire and the components in a circuit.
This flow of electrons is caused by the presence of a battery, which creates a potential difference in the circuit. As a result of this potential difference, the electrons in the wire flow from the negative pole of the battery towards the positive pole (passing through the wire and the components of the circuit).
Answer:
The car that is accelerating is B a car that rounds a curve at a constant speed
Explanation:
Although all of the cars are at a constant speed or not moving acceleration is the change in speed or the change of directions therefore making the only car changing directions your answer.
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
