What is electric charge?</h3>
Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge.Electric charges can be positive or negative (commonly carried by protons and electrons respectively). While like charges repel one another, opposite charges attract. An object that has no net charge is said to be neutral. For problems that do not require taking into account quantum events, classical electrodynamics—the term used to describe early understanding of how charged particles interact—remains true.
Since the net charge—the total of the positive and negative charges in an isolated system—is an electric charge, it is a conserved property. Subatomic particles carry an electric charge.

Answer:
77.3W (to 3sf)
Explanation:
weight = mass × gravtaional field strength
= 6.35kg × 10N/kg
= 63.5N
weight = force = 63.5N
work done = force × distance
= 63.5N × 5.11m
= 324.485J
power =
=
= 77.3W (to 3sf)
Energy is the capacity to do some type of work
Answer:
f/4
Explanation:
Explanation: Gravitational force between two objects varies directly as their masses and inversely as the square of the distance between them. So, when the masses of both objects are halved without changing the distance, the gravitational force between them would become one-fourth of the original value
Answer
the medium does not change the speed of the on they should change.
Explanation:
The speed of the waves is constant for a given medium, depending on the physical properties of the medium,
When a wave is strapped on a wall of a medium it does not change the properties of the medium, the wave changes direction, but since the medium does not change the speed of the on they should change.
