Which of the following statements is not true?

Physics
1 answer:
djyliett [7]4 years ago
4 0

Answer:

Explanation:

1 ) Average power supplied to an inductor is zero because the phase difference of potential and current is π / 2 .

So it is a wrong statement .

2 ) Step up transformer increases the voltage . At high voltage , lesser current is required to transport electrical energy . When current is reduced , the loss of energy due to heating effect is reduced .

3 ) voltage and current are in phase in resistance  in ac .

3 ) RMS stands for Root Mean Square .

A 4.1 object is lifted to a height of 4.5m above the surface of Earth.What is the potential energy of the object due to gravity?
liberstina [14]

Answer:

P = 180.81 J

Explanation:

Given that,

Mass of a object, m = 4.1 kg

It is lifted to a height of 4.5 m

We need to find the potential energy of the object due to gravity. It is given by the formula as follows :

P = mgh Where g is acceleration due to gravity

P = 4.1 kg × 9.8 m/s² × 4.5 m

P = 180.81 J

Hence, the potential energy is 180.81 J.

What effect does dropping the sandbag out of the cart at the equilibrium position have on the amplitude of your oscillation?.
Ber [7]

Answer:

It has no effect on the amplitude.

Explanation:

When the sandbag is dropped, then the cart is at its maximum speed. Dropping the sand bag does not affect the speed instantly, this is because the energy remains within the system after the bag as been dropped. The cart will always return to its equilibrium point with the same amount of kinetic energy, as a result the same maximum speed is maintained.
