Answer:
a. passing from south end of solenoid to north end and is decreasing in magnitude
Explanation:
by taking into account the Lenz's law
From the Lenz's law we know that if the self-induced emf is due to a decrease in the current, the self-induced current is in a opposite direction. In the other case, when the current increase, the self-induced current is in the same direction that the initial current in the solenoid.
If we assume the second case (the current is increasing) the change in the magnetic flux is negative and the self-induced current contributes to the initial current
I hope this is usefull for you

Answer:
Radiofrequency Ablation (RFA) which is a type of Electrical Energy is used to treat cancer. If it sees heat made by radio waves to kill cancer cells. Ablation means destroying completely. The method is putting RFA a probe (electrode) that goes through the skin into the tumor. A CT scan is needed so to check that the probe is in exactly the right place. An electrode in the probe creates radiofrequency energy to produce heat and kill the cancer cells.
Explanation:
The answer is C adding more mass(Tape) to the balls(No homo) would increase the gravitational pull.
I believe the car because it has the most mass
At 60 mph. The 18-wheeler is moving slower, so its molecules have less kinetic energy.
