Question

If the system s the phone only which the follling statements is ture during this proecess?

Answer 1

The question is incomplete and unclear. Without more information, it is not possible to determine which statements are true or false during the process of a phone system.

Step-by-step explanation:

The question seems to be incomplete and unclear, but from what can be understood, it is about the statements that are true during the process of a phone system.

For a correct answer, we would need more information about the phone system and the context of the process. Without that information, it is not possible to determine which statements are true or false during the process.

Answer 2

If the system is the Phone Only, the true statements during this process are:

• I. The Earth did work on the system
• II. The system has gravitational potential energy

I. The Earth did work on the system because when the system is in a gravitational field, like Earth's and it moves vertically or changes its height work is done on it. This work is equal to the change in gravitational potential energy (U) of the system.

II. The system has gravitational potential energy (U) because any object in a gravitational field has the potential to do work due to its position.

This potential energy is calculated using the formula U = m * g * h, where m is the mass of the system, g is the acceleration due to gravity and h is the height of the system above a reference point.

So, as long as the system is in a gravitational field, it possesses gravitational potential energy.

If the system is the Phone Only, which of the following statements is true during this pro cess? Explain your choice. I. The Earth did work on the systenm II. The system has gravitational potential energy (UG and U II. Both I and II are true.
