Which two statements about an electric motor are true?
it converts motion energy to electric energy.
it depends on the relative motion of a magnet and a current-carrying wire.
it depends on a rotating magnet to create a magnetic field.
it converts electric energy to motion energy.
it doesn't require electricity because it uses electromagnetism.

It depends on the relative motion of a magnet and a current-carrying wire and It converts electric energy to motion energy are the correct statements about an electric motor.

Explanation:

A motor is a mechanism that transforms electrical energy into motion energy. With an electric motor, control could effortlessly be conveyed through electricity from one point to another. The electric motor is based on the principles of electricity and magnetism.

Electrical motors regenerate energy to one form or another by the act of magnetic fields. When a coil conducting current is located at a right angle to a magnetic field, a force will be produced that impels it out of the field.

It depends on the relative motion of a magnet and a current-carrying wire and It converts electric energy to motion energy are the correct statements about an electric motor.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
