Answer:
-0.045 N, they will attract each other
Explanation:
The strength of the electrostatic force exerted on a charge is given by

where
q is the magnitude of the charge
E is the electric field magnitude
In this problem,

(negative because inward)
So the strength of the electrostatic force is

Moreover, the charge will be attracted towards the source of the electric field. In fact, the text says that the electric field points inward: this means that the source charge is negative, so the other charge (which is positive) is attracted towards it.
Answer:
if there is no friction in a simple machine, work output and work input are found equal in that machine
Explanation:
Answer:
cold water strengthens the magnetic attractive force.
Explanation:
The molecules within the magnet will move slower because they have less kinetic energy,so there is less vibration within the magnets molecules.
Answer:
A.
Explanation:
momentum depends on weight and speed
Answer:
Hey Krista: Burning is a type of chemical change using fire and heat that produces new substances "Buming"* things like wood or bread changes their color and odor
This is the best discription because it describes what things can burn and what happens to them.
*i don't know what "buming" means but i think you mean burning, lol.
