Answer:
2280 V
Explanation:
distance between the plates, d = 4 cm = 0.04 m
Electric field strength, E = 5.7 x 10^4 V/m
The formula for potential difference is given by
V = E x d
V = 5.7 x 10^4 x 0.04
V = 2280 V
thus, the potential difference between the plates is 2280 V.
Answer:
Free-body diagrams are defined as the diagram that represents the direction and magnitude of all forces that act on an object.
There are some limitations of the free-body diagrams, that are:
- The free-body diagram is based on coordinate system that increases the complexity of the diagram.
- There are lot of forces acting on an object such as friction, gravity, drag, tension, and normal force and to calculate the end result, it is important to determine the correct direction of all the forces otherwise wrong direction of any one of the force can give the wrong answer.
- Free-body diagrams do not depend on the size and shape of the body, that is why unable to calculate the rotation and torque.
Answer:
The gravitational force between them increases by a factor of 4
Explanation:
Gravitational force is a force of attraction between two objects with masses M and m which are separated by a distance R. It is given mathematically as:
Fg = GMm/R²
Where G = Gravitational constant.
If the distance between their centers, R, decreases by a factor of 2, then it means the new distance between their centers is:
r = R/2
Hence,the gravitational force becomes:
Fg = GMm/r²
Fg = GMm/(R/2)²
Fg = GMm/(R²/4)
Fg = 4GMm/R²
Hence,the gravitational force increases by a factor of 4.
The amount of charge that passes per unit time is called <em>electric current</em> .
Current has dimensions of [Charge] / [Time] .
It's measured and described in units of ' Ampere ' .
1 Ampere means 1 Coulomb of charge passing a point every second.
The answer is circle graph because it shows how a part relates to the whole number.= )
