they're called stellar black holes and only very large stars can form them because they have enough mass to do so
Answer:
-1.67 m/s
Explanation:
We can solve this problem by using the law of conservation of momentum: in fact, since the system is isolated (no external forces, since the ice is frictionless), the total momentum of Evelyin and Lily must be conserved.
The total momentum before is zero, since they are both at rest:
The total momentum after is:
where
m = 48.3 kg is Lily's mass
M = 57.4 kg is Evelyin's mass
V = 1.4 m/s is Evelyn's velocity
v is the Lily's velocity
Since momentum is conserved,
And so
Solving for v, we find Lily's velocity:
And the negative sign indicates that her direction is opposite to Evelyn's direction.
Answer:
backward is the answer beacuse In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it.
Hello!
each element atom has a certain number of protons, which weigh 1 AMU, but the same element can have a different number of neutrons (weighing 1 AMU), which results in what is called an isotope
Normally, the atoms contain the same amount on neutrons. However, sometimes they gain more neutrons, which increases the atomic mass by 1 AMU for each additional proton.
I hope this helps, and have a nice day!
