Answer:
Angular acceleration of the disk ∝ = K
Explanation:
Given that;
Angular velocity function given by ω = Kt + L
Angular acceleration of the disk at t=T is = ?
Now,
Angular velocity;
ω = Kt + L
Angular acceleration is;
∝ = dω / dt
= 
( Kt + L )
At t = T
∝ = K
Because ∝ is not dependent on t
Therefore
Angular acceleration of the disk ∝ = K
Opposite charges attract; like charges repel :)
I'm not entirely sure, but I believe it is A Friction. because gravity pulls down, weight isn't a force, and acceleration doesn't oppose motion
Answer:
If something is traveling at a constant velocity, then forces are balanced.
Explanation:
If something is traveling at a constant velocity, then the forces must be balanced because a constant velocity is only achieved with balanced forces.

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.
