A skater increases her speed from 5.0 m/s to 10 m/s in 5 seconds. What is the acceleration of the skater?

Explanation:

The acceleration of an object is the rate of change of velocity of the object; it is given by:

where

u is the initial velocity of the body

v is its final velocity

t is the time elapsed

In this problem, we have:

u = 5.0 m/s is the initial velocity of the skater

v = 10.0 m/s is the final velocity

t = 5 s is the time elapsed

Therefore, the acceleration of the skater is:

radiation

explanation:

heat is transmitted by radiation

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
