There's no such thing as one balanced force or one unbalanced force.
If ALL of the forces in a GROUP of forces acting on the same object
all add up to zero, then we say that the GROUP of forces is balanced.
If they don't, then the GROUP of forces is unbalanced.
Two or more forces can be balanced or unbalanced.
One force can't.
Answer:
The centripetal acceleration of the object is .
Explanation:
We have,
Radius of a circular path is 200 m
It takes 5 seconds to complete 10 revolutions. The angular velocity of the object is given by the rate of change of angular displacement per unit time :
The centripetal acceleration of the object is given by :
So, the centripetal acceleration of the object is .
They spill out chemicals into our air that may be bad for our lungs
Answer: 2 diodes
Explanation:
Given : In proof testing of circuit boards, the probability that any particular diode will fail is 0.01.
The number of diodes contained by circuit board = 200
Then , the expected number of diodes to fail is given by :-
Therefore, there are 2 diodes that we will expect to fail.
