When you are finding the kinetic energy, it is best to keep this formula in mind.
Ek = 1/2mv²
Where m is mass and v is velocity. Basically sub the numbers in to find the kinetic energy for each. In this case, subbing all the numbers, the smallest change in kinetic energy is the Lineman with a kinetic energy of just 540N.
I didn’t see any of the following but I can say that one reason they use it is to record their findings
Dew-point: <span>the temperature to which air must be cooled, at a given pressure and water-vapor content, for it to reach saturation; the temperature at which dew begins to form.</span>
It is dry in deserts and hot too. There are special kinds of plants that grow in desserts means they have specialized characteristics which help them beat the dry and hot weather.
Succulent plants such as cacti, aloes, agaves have ability to store water in their leaves and stems which have thick and hard outer layer to avoid evaporation of water.
These plants have small spicules on their outer surface which protects them from animals as well.
