Answer:
The displacement of the spring due to weight is 0.043 m
Explanation:
Given :
Mass 
Kg
Spring constant 
According to the hooke's law,
Where 
force, 
displacement
Here,
( 
)
N
Now for finding displacement,
Here minus sign only represent the direction so we take magnitude of it.
m
Therefore, the displacement of the spring due to weight is 0.043 m
Answer:
It would be A
Explanation:
velocity is speed and direction
I am pretty sure it is False because qualative data includes things you can't measure usually containing your 5 senses
Therefore, if the block moves from its position of maximum spring stretch to maximum spring compression in 0.25 s, the time required for a full cycle is twice as much; T = 0.5 s.
Answer:
A
Explanation:
Electromagnet: It is a temporary magnet. It consists of wrapping coils around iron core and the power source. When the current passes through the coils around the iron core then it will get magnetized. The domains of the electromagnet gets aligned.
As long as the current passes through it, it will get magnetized. It will loose its magnetism easily when the power is switched off.
In the electromagnet, the strength of the magnetism can be increased or decreased. The poles of the electromagnet are not fixed.
