Complete Question
The maximum electric field strength in air is 4.0 MV/m. Stronger electric fields ionize the air and create a spark. What is the maximum power that can be delivered by a 1.4-cm-diameter laser beam propagating through air
Answer:
The value is 
Explanation:
From the question we are told that
The electric field strength is 
The diameter is 
Generally the radius is mathematically represented as

=> 
=> 
Generally the cross-sectional area is mathematically represented as



Generally the maximum power that can be delivered is mathematically represented as

Here c is the speed of light with value 
is the permittivity of free space with value 


Jupiter's diameter is 11.2 times larger than Earth. This means that Earth would be relatively small. Based on searches around the internet from reliable sources, I can conclude that the earth would be the closest to the size of a marble.
1
The flow of electrons from negative to positive.
3
Materials that can easily carry electricity from place to place.
4
Materials that do conduct electricity, just not as well as conductors.
5
Materials that stop the flow of electricity.
2
An object that slows down the flow of electric current but still allows some electric current to move, resulting in some of the energy being converted to heat (thermal energy) or light energy in the process.
Answer:
The gravitational attraction of the Sun is what holds the planets in their elliptical orbits. So to explain this the mass effects the motion of the planets because the strength of gravitational force depends of the mass.
Explanation:
In collision of the steel ball and the steel plate, the collision is an inelastic collision and there is loss in the kinetic energy.
<h3>What are collisions?</h3>
Collisions occur when two objects that are moving in the same directions or in different direction meet each other and collide.
There are two types of collisions:
- elastic collision - the kinetic energy is conserved
- inelastic collision - there is a loss in kinetic energy
In the collision of the steel ball and the steel plate, there is loss in the kinetic energy of the steel ball which is converted to sound energy.
In conclusion, the collision of the steel and steel plate is an inelastic collision.
