The magnetic force on a current-carrying wire due to a magnetic field is given by
where
I is the current
L the wire length
B the magnetic field strength
In our problem, L=1.0 m,
and
, so we can re-arrange the formula to find the current in the wire:
Answer:
unbalanced force
Explanation:
According to Newton the determining factor on if and how an object will move is the unbalanced force acting upon that object. In Newton's first law he states that an object will remain at rest unless acted on by an unbalanced force. This unbalanced force needs to be stronger than any opposite force being acted upon by the same object. Enough so that the object exits its state of rest and begins moving in the direction in which the force is being applied. If the force is not strong enough to overcome the opposite forces then the object will not move.
The pressure within the can would increase upon heating and decrease upon cooling.
Answer:
Explanation:
Given
,,,
The tension of the spring is
The force in the spring is equal to centripetal force so
But Fc is also
Fc=KxΔr
Replacing
total distance is
In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
