Communicate the ideas of a projectile in the absence of air resistance that. (i) Horizontal component (VH) of velocity is constant. (ii) Acceleration is in the
vertical direction and is the same as that of a vertically free falling object. (iii) The
horizontal motion and vertical motion are independent of each other

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

The energy produced as a result of this flow of electrons from atom to atom is called

What quantity do units represent in value
