Answer:
The amount of electrons that flow in the given time is 3.0 C.
Explanation:
An electric current is defined as the ratio of the quantity of charge flowing through a conductor to the time taken.
i.e I = ...................(1)
It is measure in Amperes and can be measured in the laboratory by the use of an ammeter.
In the given question, I = 1.5A, t = 2s, find Q.
From equation 1,
Q = I × t
= 1.5 × 2
= 3.0 Coulombs
The amount of electrons that flow in the given time is 3.0 C.
Answer:
Explanation:
Given that,
The mass of a Moon,
The mass of the Earth,
The moon's mean orbit distance around the earth is,
We need to find the gravitational force exerted on the moon by the Earth.
The formula of gravitational force is given by :
So, the required force is .
Answer:
20N
Explanation:
Given parameters:
Work done = 200J
Distance moved = 10m
Unknown:
Amount of force applied =?
Solution:
Work done is the force applied on a body to move it in the direction of the force.
Work done = force x distance
The unit of work done is in joules
Since the unknown is force, we make it the subject of the expression;
Force =
Force = = 20N
