A, Lenz' Law. There need to be a difference of flux, so if you use AC you will get a current too.

Answer:
<em>Only gravity acts on B but there is an additional residual force from the hand on A.</em>
Explanation:
All bodies are constantly under the effect of gravity. Gravity is what gives us weight here on earth. Gravity acts downwards, and helps to decrease the deceleration of a body moving up and accelerating a body that travels downwards. For the ball A, traveling upwards, the upwards movement is due to the force on it impacted on it from the hand. As A tries to go up, gravity tries to decelerate it until it will come to a stop and then fall downwards under gravity. For body B, descending down means that only gravity forces acts on it at that point, if we ignore buoyant forces and air resistance. And B accelerates as it falls down towards the juggler.
Answer:
- The independent variable its A, the temperature.
Explanation:
There are two variable in this (mental) experiment. The temperature and the gender of the alligator.
The temperature its the independent variable, its the one we can control using the incubator.
The gender of the alligator, its hypothesized, will be determined by the temperature, so, its the dependent variable in our hypothesis.
The incubator will be used in all the eggs of the experiment, so, its not a variable.
The male alligators its one of the possible outcomes of the experiment. Again, not a variable.
