Answer:
Resistor
Explanation:
Resistor provides resistance to the flow of electric current in a circuit.
It controls the amount of current in a circuit by acting as a barrier to the flow of electric charges
In order to measure the size of the electrical current flowing in the circuit,
the current must pass through the meter.
Longitudinal waves have energy that vibrates parallel to the medium - a compression is the region of greatest density and the rarefaction the region of highest density .The rarefaction (much like the maximum amplitude in a transverse wave) has a region of lowest density, typically situated in the exact center of the region.
Frictional force always opposes applied force, so the net force on the cart would have to be 19N - 1.7N. The acceleration can then be solved by using the relation: F = ma. This is shown below:
Net force = 19 - 1.7 = 17.3 N
Acceleration = Force / mass
Acceleration = 17.3 / 2
Acceleration = 8.65 N/m
