Answer:
The tension in the tow rope pulling the log is 784.61 N
Explanation:
Given:
v = speed = 13 m/s
Pf = final power when the log is pulled = 8.5x10⁴W
Pi = average power = 7.48x10⁴W
The force required to move a car is equal to:


T = Ff - Fi = 6538.46 - 5753.85 = 784.61 N

The last one.
One grey sphere, Four white spheres, and One red spheres
Answer:
A. a motor
Explanation:
A motor is an electrical device or machine that converts electrical energy into mechanical energy. That is, a motor takes electrical energy to produce motion. There are different types of motors such as DC motor, induction motor and so on.
When electrical current flows through a coil, a magnetic flux is been produced, therefore when a rotating power source is supplied to coil of a motor, a magnetic field is produced which causes torque.
