Answer:
Currents in the aluminum sheet set up a magnetic field that opposes the oscillations
Explanation:
It has been stated in the question that the aluminum sheet hangs from one of the arms and passes between the poles of the magnet and causes the magnetic field to decay rapidly. In the absence of this magnetic breaking, the oscillation may continue for a long time.
As the aluminum hangs from one of the sheets and passes between the poles of the magnet, the magnetic flux linked to the sheet changes and emf is induced in the sheet according to Lenz law. As a result of this induced emf, eddy currents are developed on the plate. The Eddy currents opposes the magnetic force on the aluminum sheets. This opposes the oscillation of the aluminum sheet and causes it to come to rest.
Answer:
Gas molecules move at different speed at a given temputure bc as temp increases they move faster
Explanation:
they move faster bc they gain kinetetic energy
If we r talking about the whole atom, we would see that the atom have higher number of protons (positive charges)than electrons (negative charges). That means the number of positiv charges are dominating over the number of negative charges which makes the atom a positiv charges atom
