Answer:
Part c)
Explanation:
Part a)
As per Coulomb's law we know that force on a charge placed in electrostatic field is given as
now acceleration of charge is given as
now if charge moved through the distance D in electric field and its speed changes from vo to fraction f of speed of light c
then we will have
so we have
Part b)
Now using work energy theorem we can say that total work done by electric force on moving charge will convert into kinetic energy
So we will have
so we have
Part c)
Now if an electron is accelerated using this field
then we have
so we have
Answer:
Explanation:
Electrical energy is energy derived from electric potential energy or kinetic energy.
Or,
Electrical energy is a form of energy resulting from the flow of electric charge. Lightning, batteries and even electric eels are examples of electrical energy.People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.
Hope it helped you.
The answer is 560 because 7 times 80 is 560. Please mark me as the brainliest.
Answer:
where F is the friction force that is the same for both boxes
Explanation:
So the same boxes at the same mass m would create a same friction force, let this force be F. The net force in the first and 2nd cases would be
- 1st case: F1 - F
- 2nd case F2 - F
According to Newton 2nd law, this net would make acceleration
- 1st case
- 2nd case
Since
