Answer:
a = Δv/t = (vf - vi)/t = (0 - 5)/4 = -1.25 m/s²
Explanation:
You may or may not need the negative sign, depending on how the question designer was thinking about the problem.
When a current is passed through a coil of wire with a piece of iron inside, the one that will be formed is :
an electromagnet
It happens when a soft metal core made into magnet by passage of electric current

The potential energy of a 2-μc charge at that point in space is
joules.
Given,
V=400v, q=2-μc=2*
,
U(potential energy)=V*q=400*2*
=
joules.
<h3>Potential energy</h3>
The energy that an item retains due to its position in relation to other objects, internal tensions, electric charge, or other reasons is known as potential energy in physics. The gravitational potential energy of an object is based on its mass and the distance from the centre of mass of another object. Other common types of potential energy include the elastic potential energy of an extended spring and the electric potential energy of an electric charge in an electric field. The joule, denoted by the sign J, is the SI's definition of an energy unit.
The vectors that are described as gradients of a particular scalar function known as potential can be used to represent these forces, also known as conservative forces, at any location in space.

Red dwarfs include the smallest stars commonly weighing between 0.075 to 0.50 percent the mass of the sun, their small size means they burn at a slower rate meaning a dwarf star is to long exceed the life of the universe, their reduced mass also means their surface is very cool
