Answer:
B)
Explanation:
The electric force between charges can be determined by;
F =
Where: F is the force, k is the Coulomb's constant, is the value of the first charge, is the value of the second charge, r is the distance between the centers of the charges.
Let the original charge be represented by q, so that;
= 2q
=
So that,
F = x
= 2q x x
= x
= x
F = x
The electric force between the given charges would change by .
Answer: C) 200 N
Explanation:
The force is defined as:
Where:
is the mass of the object
is the acceleration
Then:
Finally:
Hence, the correct option is C.
The answer would be the sound waves.
the force applied when using a simple machine is called the effort force
Answer:
a= 0.5m/s^2
Explanation:
Force applied on an object is known as
F=m.a (Newton's second law states it)
a=F/m
a=5/10=0.5m/s^2
