Answer: The average speed of the object is 1.95 m/s.
Explanation:
Distance traveled by an object in the first interval, = 2 m
Time is taken in firsts interval = 2 s
Distance traveled by an object in the second interval, = 80 mm
Time taken in second interval = 40 s
The average speed of the object is 1.95 m/s.
The frequency and wavelength of the wave cannot change as it travels from one medium to another.
Velocity measures both speed and direction that an object travels. The magnitude of velocity represents the speed of the object, while the direction of velocity indicates the direction in which the object is moving.
When light travels from one material to another, it can be reflected, refracted, or absorbed. The degree to which each of these behaviors occurs depends on the properties of the two materials and the angle at which the light intersects the interface between them.
Energy travels from one place to another during a wave motion. Particles in the medium may also oscillate in place as the wave passes through, but they do not permanently move from one location to another.

Average speed is the total distance traveled divided by the elapsed time. A car that travels 60 miles in one hour, stops for one hour and travels 60 miles for another hour, has an average speed of 120 miles / 3 hours, which is 40 mph.
A person who travels to another place for a holiday is a tourist.
