Answer:
Energy is carried by the electric and magnetic fields
Explanation:
Electromagnetic waves consist of electric fields and magnetic fields which oscillate perpendicularly to the direction of propagation of the waves (for this reason, they are called transverse waves).
Electric fields and magnetic fields both possess energy, and this energy is carried through space by the wave. Note that electromagnetic waves do not carry matter, but only energy (in fact, they do not have mass). Moreover, electromagnetic waves are the only type of waves that do not need a medium to propagate: in fact, they can also travel through a vacuum.
The net force is (40 Newtons) (down the road).
But 40 Newtons is not going to move a piano very enthusiastically.
Correct answer choice is:
C. Medium range
Explanation:
Medium range exercises are used to gain extra strength and fitness. Usually, heavyweights are used with less number of repetitions. These sort of exercises are mostly the hardest t do. All you need is to have a high level of motivation and stamina, which can be gained by running or cycling.
Mechanical or Electromagnetic
