Answer:
Higher current is normally achieved by faster moving electrons.
Explanation:
- Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.
- Current is the net charge flowing per unit time.
- Current can be represented by:
I=v×e×N×A
where,
I= current
e= electric charge
v= speed of electrons
N=no. of free electric charges per volume
- The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.
Elastic energy (E1) stored in the spring when it is stretched by x :
<span>=1/2kx^2=1.5J </span>
<span>when it is stretched 3 times more=>x becomes 3x
</span>so
<span>E2=1/2k(3x)^2 </span>
<span>=1/2k{9x^2} </span>
<span>=9{1/2kx^2} </span>
<span>={(E1}</span>
<span>=9{1.5} </span>
<span>=13.5J
hope it helps</span>
It's either C. or D. its either one just keep reading the question over and over okay it will help i promise
Answer:
generate electricity or power
