Answer:
Explanation:
It means that you only need apply 1/4th of the actual force required to operate the lever as you have an mechanical advantage which permits you to do 4 times the work with the same amount of effort.
Einstein's special theory of relativity explains that the electric and magnetic fields are both can formulate together in mathematically.
It is given Einstein's special theory of relativity.
It is find the Einstein's special theory of relativity explains the perpendicular behavior of moving charges without recourse to invoking the concept of a magnetic field.
<h2>What is Einstein's special theory of
relativity?</h2>
As we know that one charge creates a field and its that field that actually exerts a force on the other charge. Here we it gives the relationship of two fields like electric field and magnetic field and gives the formula for electromagnetic objects.
Special relativity fixes the problem by the points that the magnetic force in one frame of reference easily be an electric force in other and also some of the combination of them in a frame.
Thus, Einstein's special theory of relativity explains that the electric and magnetic fields are both can formulae together in mathematically.

Sylvester James Gates' biggest discovery was the string theory which involves computer coding. I hope this answer helped.
Answer:c
Explanation:
When the direction of current is towards the observer then the magnetic field around it will be in the form of concentric circles and its direction will be anti-clockwise when viewed from the observer side.
Whenever current is flowing in a current-carrying conductor then the magnetic field is associated with it and direction of the magnetic field is given by right-hand thumb rule according to which if thumb represents the direction of current then wrapping of fingers will give the direction of the magnetic field
Answer:
A. 
B. rev=10.79rev
Explanation:
A.
500rpm
the time is about 2.60s knowing the acceleration is:
so:
B.
The CD stop so the final velocity is vf=0 so:
Total revolutions:
