The magnetic field is decreasing. What is the induced electric field?
melisa1 [442]

Answer: The induced electric field will be constant i.e zero

Explanation:

Magnetic field is a region of space where magnetic force can be felt while electric field is a region of space where electric force can be felt. This two field are related because they tend to talk about force of attraction and repulsion. Example is running a current through a thin wire near a magnet, the direction of one of the field will determine the direction of the other.

According to the question, if the magnetic field is decreasing, the electric field will adjust by traveling in opposite direction to the magnetic field just to make the field constant.

When do mountain formations occur?
Bezzdna [24]
Mountains can form many ways. a few are when divergent plates move abort and lava comes through the crack evenly forming up to what Hawaii is today. Another is when convergent plates collide moving upward forming mountains.

The momentum of a neutron p = 586.25 kg m / s.

<u>Explanation:</u>

The product of mass and the velocity gives the momentum of an object and it is a vector quantity. It is denoted by the letter p. The unit of momentum is kilogram meter per second (or) kg m / s.

Given mass m = 1.675 \times 10,            velocity v = 3.500 \times 10

                  Momentum, p = mv

where m represents the mass,

          v represents the velocity.

                   momentum p = (1.675 \times 10) \times (3.500 \times 10)

                   momentum p = 586.25 kg m / s.

TRUE OR FALSE. When non-conservative forces are present, the amount of work done increases with the length of the path.
Ymorist [56]

Answer:

True

Explanation:

When non-conservative forces are present, the amount of work done increases with the length of the path, this is true because, when a force is applied, the force does when and the non-conservative forces also do work. Since the non-conservative force work against the force  applied, this tend to increase the net work done by the applied force to compensate for the loss in energy due to the work done by the non-conservative forces.
