m=5.2kg
A small dense centre that has a positive charge and is surrounded by moving electrons is called an Atomic Nucleus.
Answer:
Explanation:
Given that there are boys (plural) only at a height of 3 meters, they still might have more energy than a single girl.
The girl might have a mass of 50 to 60 kg. The boys will likely have slightly more.
Girl PE
PE = 5 * 50 * 10
PE = 2500 N
Boys
PE = 3 * 120 * 10
PE = 3600 N
That's with 2 boys on the 3 meter board. The girl would have a PE more than 1 boy likely or possibly.
Hey you!
No one really knows why galaxies don't fly apart. Blackholes do, very strongly, have a gravitational pull on them, but that isn't enough to keep billions of stars and planets and other space matter in orbit around them. Although, the stars and gases are held together by the gravity of dark matter, so, you could say that explains why.
