<span>The work done is 3.0 Nm.
We can us the equation Work = Force * Distance, where Force = 75.0 N, and distance is xf – xi = 3.00 cm - -1.00 cm = 4.00 cm. Convert centimeters to meters by moving the decimal place to the left by two places to get 0.04 m. Plug these values into the Work equation:
Work = Force * Distance
Work = 75.0 N * 0.04 m
Work = 3.0 Nm</span>
Kinetic and static friction are both resistive forces
I believe your answer is correct, because 8.7*10^-7 is equal to 0.00000085347.
Hope you do well!
C.half the energy is carried by the electric field and half is carried by the magnetic field.
