A horizontal force of 8N being applied to an object with a mass of 4.0-kg. **What is the blocks acceleration?

 d)

Explanation: d) What is the acceleration of the Earth due to the force of the person? ... What is the net force acting on an object that is being pulled by a force of 5 N at 30°, ... A cart having a mass of 15 kg, rolling from left to right on a horizontal surface, ... Fging -(15kg) (4,81162) 147.15 N ... 12-newton force being applied to two blocks, A.

Explanation:

2 m/ s² acceleration because you know that F= ma.

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.
