A 55kg skier accelerated at 3 m/s^2. How much force must the skier exert?

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

From the question

mass = 55 kg

acceleration = 3 m/s²

We have

force = 55 × 3

We have the final answer as

Hope this helps you

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
