Answer:

B. Objects do not have to touch each other to experience a force.

Explanation:

For example ..One of the noncontact forces is magnetic force whereby a magnetic object will be attracted to another magnetic object of oppsite charged particles, through waves called electromagnetic waves. On the other hand, the two magnetic objects of similar charged particles can repel through electromagnetic waves..

Read the following statement.
Sergio039 [100]

The statement  "the knowledge produced by science builds on old ideas and is constantly changing" is absolutely agreeable.

We can see the above statement repeating itself in various situations and has led to the discovery of new laws which are now used in all areas of science. The best example of the above statement is The universal gas law, PV = nRT, which is the combination of two laws, Boyle's law, Charle's Law and Avogadro's Law.

According to Boyle's Law, gas volume grows as pressure lowers.

Charles' Law states that the gas expands in volume as its temperature rises.

As per Avogadro's Law, that as the gas concentration rises, so does its volume.

An outside force, Fo, brings two small metal spheres, A and B, at rest from a long distance away to a point where they are 1 met
Ksenya-84 [330]

Answer:

1)

The total work done by outside force is W_{o}=0.294J

2)

The total work done by the electric field is -W_{o} =-0.294J

3)

The potential energy of the two sphere system is  PE = W_{o} = 0.294J

4)

The magnitude of the acceleration of sphere A is a_{A} = 66.868m/s^2

5)

The magnitude of the acceleration of sphere B is a_{B} = 26.747 \ m/s^2

6)

The magnitude of velocity sphere A after a very long time is  v_{A} = 10.251 \ m/s\

7) The magnitude of velocity sphere B after a very long time is  v_{B} = 4.1 m/s

 

Explanation:

The explanation is shown on the first and second uploaded image
