Sound waves are known as longitudinal waves. Longitudinal waves are also known as compressional waves. These are waves that are made up of a series of compressions and rarefactions. In a longitudinal wave, the motion of the medium is parallel to the direction of the wave. While in transverse waves the motion of the medium is at right angles to the direction of the wave.
Answer: Radio signals sent through space
Explanation:
>Radio signals are electromagnetic signals which can travel through space even in vacuum where no air is absent . Radio signals carry energy in the form of electromagnetic wave .
>Thunder heard from many miles away is due to propagation of sound wave in the air or atmosphere . The sound wave carries energy in the form of mechanical energy which can not propagate in vacuum and requires a medium .
>When nuclei of atoms split into parts they fly away from each other with some speed carrying kinetic energy which is a part of mechanical energy .
Thus mechanical energy is involved in all the given examples expect the case of radio signals sent through space.
Answer:
backward is the answer beacuse In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it.
A.
Explain
Metals are good conductors of heat, which is important for cooking (both heating and cooling occurs rapidly
