If the electron goes a distance d, the amount of work done on it by the magnetic field is zero.
Because magnetic force acts perpendicular to the direction of motion, it has no effect on any moving charge particle. As a result, speed won't change.
<h3>What is Magnetic field?</h3>
- The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field.
- A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.
- A compass, a motor, the magnets that hold items in refrigerators, railroad tracks, and modern roller coasters are examples of devices that use magnetic force.
- A magnetic field is created by all moving charges, and any charges that move across its regions are subject to a force.

Answer:
Mass spectrometry is an analytical technique that measures the mass-to-charge ratio of ions. The results are typically presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio.
Explanation:
Tip your bucket into a mass spectrometer. It turns the atoms into ions Then it will separate the ions by passing them first through an electric field, then through a magnetic field, so they fan out into a spectrum
Answer:
The length of the train in the frame of the lecture room is 40.59 m.
Explanation:
Given that,
Speed = 0.894 c
Original length = 90.6 m
We need to calculate the length of the train in the frame of the lecture room
Using formula of length contraction
Where, 
=original length
v = speed of train
Put the value into the formula
Hence, The length of the train in the frame of the lecture room is 40.59 m.
Answer:
D. Synthetic polymers are inexpensive to produce.
Explanation:
Hailey should include that synthetic polymers are inexpensive to produce as a benefit of synthetic polymers.
Synthetic polymers are artificially produced. These polymers come about from petroleum oil. Their hydrocarbons are industrially worked to produce the long chain hydrocarbons to form polymers.
Most of these polymers are very cheap to produce and does not cost too much. This is why they almost found everywhere.
