The classical physics works on the Newton's laws of motion. It is applicable on heavenly bodies which are governed by the gravitational force. On the other hand, Quantum Physics is applicable for very low mass and sized bodies like electron, protons etc. The classical physics would accurately describe the motion of satellite moving with speed 7500 m/s using the following formula:
where G is the gravitational constant, M is the mass of the planet and v is the orbital speed. Then radius of the orbit can be described by this formula.
That could be an electromagnet,
and it could also be an solenoid.
This is called the perihelion.
<u>Answer:</u>
The correct answer option is C. buzzer.
<u>Explanation:</u>
We know that Jeff's father needs to get a device from his workshop that converts electrical energy to sound energy.
So from the given options, buzzer is the best option Jeff's father can install in his house's security system.
An electric buzzer converts an electrical oscillating voltage into a sound output. In other words, the electrical pulses are converted into sound vibrations.
The object in the lower orbit will move faster in its orbit, and will have a shorter orbital period. None of that depends on their masses either.
