Answer:
The feeling of weight is one of compression.
Explanation:
All your body is being pulled down by gravity yet your feet ( if standing) or your back or something is holding you up.
Your body is compressed by the PAIR of forces and it is that compression that you feel.
So when you remove the supporting force then all the body is free to move together and there is no compression within you.
Hence you perceive no weight.
Explanation :
The transfer of heat continues untill the two bodies reach thermal equilibrium.
The heat can be transferred in via some processes like conduction, radiation and transfer of energy by changing of phase.
(1) Conduction : It is the transfer of heat via a solid. Heat can be transferred from one solid body to another.
(2) Convection : It is the transfer of heat from one place to another by the movement of fluids. Fluids include both liquids and gases.
(3) Radiation : It is the process of transfer of heat through electromagnetic waves. It is generated by the thermal motion of particles. All matter having a temperature greater than absolute zero emits radiation.
This property of a wave is reflection.
Reflection of a wave is the process by which waves such as light, sound , infrared, or radio waves, hits and object and bounces off it. It is the change in direction of a wave front at an interface between two different media so that the wavelength returns into the medium of origin. From the law of reflection for a specular reflection the angle at which the wave is incident on the surface is equal to the angle at which it is reflected.
That's true. Displacement is measured between the start-point and
end-point, regardless of the route that's followed. So, for example,
the displacement of an object that's moving in a circle becomes zero
every time the object returns to the point on the circle where it started.
