Answer:
(a) the runner's kinetic energy at the given instant is 308 J
(b) the kinetic energy increased by a factor of 4.
Explanation:
Given;
mass of the runner, m = 64.1 kg
speed of the runner, u = 3.10 m/s
(a) the kinetic energy of the runner at this instant is calculated as;
(b) when the runner doubles his speed, his final kinetic energy is calculated as;
the change in the kinetic energy is calculated as;
Thus, the kinetic energy increased by a factor of 4.
It would be the lithosphere

Answer:
Insulator
Explanation:
A body that has relatively few free electrons and offers comparatively great resistance to the movement of free electrons is an <u>INSULATOR</u>.
An insulator is a body that offers resistance to free flow of electrons. Insulators do not allow the passage of electric current. Examples of Insulators are glass, plastic, rubber, dry wood, paper, etc. The opposite of an insulator is a conductor. A conductor is body that allows free flow of electrons. Conductors allow the passage of electric current. Metals are the most common example of conductors such as copper, aluminum, gold, and silver. Other examples of conductors include grahite and human body.
