Electric circuit. Hoped that helped
Electrons are negatively charged so an excess will produce a negative charge.
Answer:
d. at the same velocity
Explanation:
I will assume the car is also travelling westward because it was stated that the helicopter was moving above the car. In that case, it depends where the observer is. If the observer is in the car, the helicopter would look like it is standing still ( because both objects have the same velocity). If the observer is on the side of the road, both objects would be travelling at the same velocity. Also recall that, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes but speed is the rate at which object covers distance and it is not direction wise. Hence velocity is the best option.
Answer: The rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
Explanation:
- The rate of energy transfer from one point to another is known as power.
- Its SI. unit is <em>Watt.</em>
Formula to compute power:
Power = 
, I = cureent, R = resistance.
Given R = 5 ohm , Current = 0.5 A.
Then, power = 
Hence, the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
Answer:
True
