A negatively charged plastic comb is brought close to, but does not touch, a small piece of paper. If the comb and the paper are
Irina-Kira [14]

If the comb and the paper are attracted to each other the charge on the paper, is D)must be positive

<h3>Laws of electrical attraction</h3>

This states that

  • Like charges attract
  • Unlike charges repel

Now, given that a negatively charged plastic comb is brought close to, but does not touch, a small piece of paper. If the comb and the paper are attracted to each other the charge on the paper, this implies that both the negatively charged plastic comb and the paper have opposite charges.

Since the charge on the plastic comb is negative, this means that the charge on the paper must be positive

So, if the comb and the paper are attracted to each other the charge on the paper, is D)must be positive

If a rock weighing 2,200 N is dropped from a height of 15 m, what is its kenetic energy just before it hits the ground
ycow [4]

Kinetic energy of the rock just before it hits the ground=KE=33000 J

Explanation:

Weight= 2200N

mg=2200

m(9.8)=2200

m=224.5 kg

initial velocity=0

final velocity =V

using kinematic equation V²=Vi²+2gh

V²=0+2 (9.8)(15)

V=17.1 m/s

now kinetic energy= 1/2 mV²

KE= 1/2 (224.5)(17.1)²

KE=33000 J

Thus the kinetic energy of the rock just before it hits the ground=33000 J

frez [133]

Explanation:

According to newtons first law of motion " A body is at a state of rest or uniform motion unless acted upon by a force (external)" which will either

1. change the direction

2. change the acceleration

3. change the velocity(moves or stop the body from moving)

4. change the shape or size
