The electric field at the surface of the cylinder is 70509.8039216 N/C
Yes
Explanation:
One can pick up a nail using the curved part of the horseshoe magnet farthest from the poles.
A horse shoe magnet has magnetic fields all around it.
- In the presence of magnetic force fields, any magnetic object will be attracted to it.
- This is the case with any magnet.
- A magnet is any object with magnetic fields all around it.
- This field causes attraction to any magnetic objects especially metals.

Tensional forces are created on a piece of string or rope or anything similar when it is pulled tight from both sides, that is, when forces are acting on both ends, thus tightening it. <span>The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.</span>
Answer:
The unit circle helps in making so many calculations and equations easy.
Explanation:
You cannot separate the knowledge of trigonometry to application in equations to physics. The unit circle is known to have a radius of one. This means that the distance from the centre of the circle, regardless of the unit of measurement, to any point of the edge of the circle is 1. Since the unit circle is very helpful in trigonometry, and trigonometry in turn is the projection of triangles and angles that is very crucial in the calculation of momentum, velocity and other factors of physics, the importance of the unit circle cannot be overemphasized in physics.
Answer:
