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.
Answer:
(a) 21.36 ohms
(b) 5.62 A
Explanation:
Parameters given:
Potential difference, V = 120 V
Power, P = 674 W
(a) Power is given as:
P = V²/R
Where R is resistance
=> R = V²/P
R = 120²/674
R = 14400/674
R = 21.36 ohms
(b) Power is also given as:
P = I*V
Where I = Current (time rate of flow of Electric charge)
=> I = P/V
I = 674/120
I = 5.62 A
<span>A bar magnet moves through a loop of wire with constant velocity, and the north pole enters the loop first the induced current will be greatest when the magnet is located so that </span>the loop is near either the north or the south pole.
