Which part of an atom is responsiblefon the flow of electricity?*​

Physics
1 answer:
svlad2 [7]3 years ago
3 0

Answer:

The Electron

Explanation:

Electrons are how some atoms let electricity flow easily. If have closely bound electrons, then they are a bad conductor, or insulator. Atoms with loosely bound electrons allow electricity to easily flow, making these types of atoms great conductors. This is the case with most metals, where their electrons are very loose, making metals, like copper, great at transmitting electricity.

If a 20 N block experiences a force of kinetic friction of 8.0 N
shutvik [7]

The coefficient of kinetic friction (μ) between the block and the table is 0.4.

<h3>What is kinetic friction?</h3>

This sis the frictional force between an object in motion with the surface in contact.

μN = ff

where;

  • N is normal reaction due to weight of the block
  • ff is frictional force
  • μ is coefficient of friction

μ = ff/N

μ = 8/20

μ = 0.4

Thus, the coefficient of kinetic friction (μ) between the block and the table is 0.4.

The energy expenditure value of traveling by car is 3.6 mj/passenger-kilometer. The value for traveling by train is 1.1 mj/passe
andrezito [222]

Answer:

Using lighter material in car construction, improving energy efficiency by enhancing engine design or replacing the engine with more efficient technologies.

Explanation:

Using lighter materials in the car construction, reducing the potential energy required to accelerate and to move the car, as well as energy losses due to rolling friction. There is evidence of such benefits by replacing steel and aluminium parts with components made of composite materials.  

Improving the design of internal combustion engines to minimize energy losses and accordingly, improving energy efficiency. A more radical approach is replacing internal combustion engines with electric engines, which offer higher efficiencies. Such conclusions can be easily inferred from model based on Work-Energy Theorem and Principle of Energy Conservation:

\eta_{engine} \cdot U_{engine} = \frac{1}{2} \cdot m_{car} \cdot v^{2} + \mu_{r} \cdot m_{car} \cdot g \cdot \Delta s

Sam is pulling a box up to the second story of his apartment via a string. The box weighs 16.5 kg and starts from rest on the gr
Katyanochek1 [597]

Answer:

Weight (mass) = 16.5 kg

velocity = 0 m/a

acceleration =2.6 m/s^2

displacement = 13.2m

now,

acceleration = velocity/ time

2.6 = 0 / t

t = o / 2.6

t = o
