If this is one of the following, it's correct
<span>"concentrating denser materials nearer the sun"
I hope this helps!

V=ir
I=10
v=120
r=?
r=v/i
r=120/10
r=12 ohm
<u>Answer</u>
81.94 m
<u>Explanation</u>
The centripetal force of an object moving in a circular path is given by:
F = mv²/r Where m is the mass of the object, v is the constant velocity and r is the radius of the curve.
F = mv²/r
3,300 = (1600×13²)/r
3,300 = 270,400/r
r = 270,400/3,300
= 81.94 m
They'll still be magnets, but they'll never be able to touch each other where they were cut.
I hope this helps you! :-)
Answer:
See bolded below.
Explanation:
Consider the " Before " and " After. " " Before, " this particle 1 was trying to catch up with this particle 2, and " after " particle one had collided with particle two. Take a look at the attachment below for a more detailed examination.
Here is how this will play out. Particle 1, with great velocity, will hit particle 2, which would mean that Particle 2 has less velocity than Particle 1. Now after the collision, energy is transferred to Particle 2, and while Particle 1 has now stopped in it's tracks, Particle 2 - with more energy than before - will continue as long as it has to before friction eventually brings it to a stop.
_______________________________________________________
From this we can conclude that Vf, from the picture below, must have less energy than V1, but more energy than V2 - and vice versa.
