My mommy wants to talk to you
I don't know why the answer is D , because I can't see the list of choices.
The only way to get 8.0 Amps is by making a serious mistake.
The current in the second picture is 4.0 Amps.
If the resistors are identical, then the effective resistance of
two resistors in parallel is 1/2 the resistance of each one.
The resistance in the second picture is 1/2 the resistance
in the first picture.
Current = (voltage) / (resistance)
Cutting the resistance in half causes the current to double.
If the current was 2.0 Amps in the first picture, it's 4.0 Amps
in the second picture.
Power is the time rate of energy transfer. It doesn't matter whether it's
electrical, chemical, mechanical, muscular, wind, food, or hydro energy.
Answer:
The slope of the position time graph gives the velocity.
Explanation:
The slope of the position time graph gives the value of velocity.
In first graph,
The slope is constant in both the parts but positive . So the velocity is also constant and positive for both the parts. and more than the second part, so the initial velocity is more than the final velocity.
In the second graph,
The slope is constant in both the parts but negative. So, the velocity is constant but negative for both the parts. Initial velocity is more negative than the final velocity.
