How do I conduct electricity
slavikrds [6]

Every material in the world can be defined in terms of how well it conducts electricity.   Certain things, such as cold glass, never conduct electricity. They're known as insulators.  Materials which do conduct electricity, like copper, are called conductors.  In the middle are materials known as semiconductors, which don't conduct as well as conductors, but can carry current.  Last, are materials called superconductors, which when brought down to very low temperatures  turn into superhighways of current -- they conduct electricity without any resistance whatsoever.

PLEASE HELP <3

Answer:

The mass of Mr. Thomson’s prius is 2650 kg.

Explanation:

We are given with, the kinetic energy of  Mr. Thomson’s prius is 641300 J

He is moving with a velocity of 22 m/s

It is required to find the mass of Mr. Thomson’s prius.

Due to his motion, a kinetic energy will possess by him. The mathematical form of kinetic energy is given by :

K=\dfrac{1}{2}mv^2

Solving for m

m=\dfrac{2K}{v^2}

Plugging all the values, we get :

m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 641300}{(22)^2}\\\\m=2650\ kg

So, the mass of Mr. Thomson’s prius is 2650 kg.
