Answer:
I would need more electrons 1.3125 10¹⁰ electrons
Explanation:
Static electricity is formed by induced charges in each part of the system, so the net charge does not change.
Let us analyze the situation presented, if the carpet acquires a positive charge, so that it does not alter the total charge in man, it should acquire a negative charge, to have a net negative charge I would need more electrons that have a negative charge.
We can know the number of electrons by a rule of proportions, if an electron has a charge of 1.6 10-19 C for a charge of 2.15 10-9 C how many electrons are needed
# = 2.15 10⁻⁹ /1.6 10⁻¹⁹
# = 1.3125 10¹⁰ electrons
The number is very high for which we will not worry about rounding since the number of electrons must be an integer
The physical change is that it changed shapes it never changed its chemical identity it would be different if the spring was rusted it's like how you can rip a piece of paper in half and it is still paper
Answer:
45degres
Explanation:
A projectile travels the farthest when it is launched at an angle of 45 degrees.
Answer:
Option 2.
Amplify; Amplify
Explanation:
Amplification of sound simply means increasing the loudness of the sound by modifying its electro-acoustic signals. To make very high and very low frequencies of sound audible by the human ear, the sounds need to be amplified by the sound system amplifier.
Sound systems modify high frequencies by amplifying them, and also, they also modify low frequencies by amplifying them. This changes their wave form and brings them into the hearing range of humans.
