<span>When a magnet moves near a wire, it's changing field causes the electrons in the wire to flow as electric current.</span>
Answer:
The answer is 2 because the formula is
wavelength=speed/frequency
Answer:
159 N
Explanation:
The force of friction, Fr is a product of coefficient of feiction and the normal force. Therefore, Fr=uN where N is the normal force and u is coefficient of friction. Here, we have two coefficients of friction but since it is sliding, then we use coefficient of kinetic energy. Substituting 0.25 for u and 636 N for N then
Fr=0.25*636=159 N
Therefore, the force of friction is equivalent to 159 N
