Answer:
The answer is D.) 90
Explanation:
the electromagnetic wave is a transverse wave. the electric field makes an angle of 90° with the magnetic field. both these fields, in turn, make an angle of 90° with the direction of movement of the wave.
I'm pretty sure B would be your answer.
The power provided by the machine is 13.24 W.
Answer:
Explanation:
Power is determined as the ratio of work done by the system or on the system to the time interval. As the work done is equal to the product of force acting on the system or by the system with the displacement experienced by the system. The power provided by the machine will be
Power = Work done /Time
As the force is given as 121 N and the displacement is given as 15.1 m in a time interval of 2.3 minutes. The time interval should be changed to seconds for each solving ability.
Time taken = 2.3 * 60 s = 138 s
Power = (121×15.1)/138 = 13.24 W.
So the power provided by the machine is 13.24 W.
