Answer: The potential energy of the cars at its maximum at the start and the end of the trip. Potential energy approaches zero when the cars are near the ground at the lowest point on the tracks. The kinetic energy of the cars is zero at the start and the end of the trip because cars aren’t moving. Kinetic energy is at its maximum when the cars are the lowest point on the track after racing down the hill. Yw:)
Explanation:
The de-Broglie wavelength of an electron when an electron is moving perpendicular to magnetic field will be same.
<h3>What is wavelength?</h3>
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
Hence,the de-Broglie wavelength of an electron when an electron is moving perpendicular to magnetic field will be same.

Answer:
During start total turns
After half of the time total turns
Total number of turns during it stop
After half of the time total turns
Explanation:
Initially the machine is at rest and then starts rotating with speed 3550 rev/min
now we will have
now we know that it took 10 s to reach the speed
so angular acceleration is given as
now it stops in 31 s so the angular deceleration is given as
now initially number of turn to reach the given speed
number of turns during it stop
Now during startup speed after t = 5 s is given as
now during it stop the speed after half the time is given as
now the number of turns is given as
So we want to know what do electric field lines show except strength of the electric field. Electric field lines are lines that show us the field strength and the DIRECTION of the electric field. If the lines point away from the charge that is producing the lines, the charge is positive, and if the lines point towards the charge that is producing them that charge is negative.
