Answer:
the easy way to describe this is to use a light as an example.
Explanation:
Voltage is pretty much the loop used to help use a lightbulb to emit light. Without voltage, we would be unable to use lightbulbs. This applies to much more than a lightbulb, but it's the easiest way to describe how voltage works.
Answer:
pushes it forward, pushes it backwards and then it moves
Ramsar has the highest level of natural radiation in the world.
Hot springs located in the Arkaroola Wilderness Sanctuary in Southern Australia are also credited with higher than normal radiation levels, due to spring water coming in contact with rocks rich in uranium and radon.
Answer:
Explanation:
Given that,
Current in a wire, I = 5 A
We need to find the magnetic field at 2m from a straight wire carrying a current of 5 A.
The magnetic field due to a wire is given by :
So, the required magnetic field is 
.
Answer: 2Mg/k
Explanation:
Let a be the extension experienced by the spring when a mass M is released from rest. And k is the force constant value
The potential energy lost by the mass is equal to that gained by the spring.
The potential energy lost by the mass = M x g x a
The energy gained by the spring = 1/2 x K x a^2
Therefore, M x g x a = 1/2 x K x a^2
Mga = Ka^2/2
2Mga = ka^2
Making a the subject of the formula,
Dividing through by a,
2Mg = ka
Therefore, a = 2Mg/k
The maximum extension produced in the length of the spring will be 2Mg/k.
