The thomson model didnt have a nucleus
By using the following formula we can calculate the
distance:
Distance = Speed x time
Speed = 55 m/s
Time = 2 hour 23 minutes = 143 minutes = 8580 seconds
Distance = 55 m/s x 8580 seconds
=471900 meters = 471.9 km
A car travels 471900 meters or 471.9 km if it was on the road for 2 hours and 23
minutes and traveled at an average speed of 55 m/s.

Yes.objects of different masses can have the same kinetic energy
<u>a).</u>
Kenny's potential energy at the top becomes kinetic energy at the bottom.
(M G H) = 1/2 (M V²)
Divide each side by 'M': G H = 1/2 V²
Multiply each side by 2: 2 G H = V²
Take the square root of each side: V = √(G H)
= √(9.8 x 3.2) = <em><u>5.6 m/s .</u></em>
<u>b).</u>
Notice in the solution for a). that each side of the equation was divided
by 'M'. The answer didn't depend on Kenny's mass, and it doesn't depend
on Cartman's mass either. Cartman and Kenny are both moving at the
same speed when they reach the bottom.
<u>c).</u>
Notice in the solution for a). that each side of the equation was divided
by 'M'. The answer didn't depend on Kenny's mass. It didn't depend on
Cartman's mass either, and it doesn't depend on Kyle's mass either, either.
Each of them is moving at the same speed when he reaches the bottom.
The same also applies to girls as well, too.
