As series resistors are added, the resistance is added directly so the total resistance will be equal to
Since the power is determined as
We have there that
The power is inversely proportional to the increase in resistance, so it will tend to decrease as more resistors are added in series.
The correct answer is: C.
Answer:
=−2.451 330 152 1*10^27J
Explanation:
The electric potential=the Voltage * Charge:
E = VQ
V = 1.53x10^8 V (positive, because the cloud has a higher potential)
Q = -1.60217657 x10^19 C (the charge of an electron)
E = (1.53x10^8 V )* (-1.60217657 x10^19 C)
E=−2.451 330 152 1*10^27J
The negative sign indicates that the potential energy is decreased by the movement of the electron.
A simple machine can make work easier by reduce the amount of energy needed to perform a task, therefore, B. <span>it magnifies the potential energy so that the kinetic energy is greater</span> is the correct answer.
Answer:
D. Tidal energy is replaced naturally by the Moon's gravity.
Explanation:
The reason tidal energy is considered a renewable energy resource is that Tidal energy is replaced naturally by the Moon's gravity. The Moon's gravity creates bulges on the side of Earth that is closest and farthest from the Moon. These bulges also pull water causing high tides in those areas. As the Earth rotates these areas experience low tide while the areas that had low tide now experience high tide. This constant shift creates tidal energy every day, which is replenished naturally.
