A) How much time did it take to hit the ground? B) What is the velocity just before it hits the ground?

Fire is plasma. Plasma is ionized gas. Ionized gas is electrified gas. Electrified objects create their own electromagnetic field. So if fire is made of electrified gas, shouldn’t it respond to magnets?

Doesn’t it mean to electrically charge gas atoms? Aren’t electrically charged things described as “electrified”?

Or is the speed things are sucked in a constant speed no matter what point you’re at in the hole (top vs singularity?) thank you in advance!

In conservation of momentum, a system of two objects starting with zero momentum, one of the objects is caused to move in one direction. The other object will move in the opposite direction. According to Newton’s first ...

Can anyone tell me the most BASIC, and watered down rundown of string theory? Pretend you’re telling a random off the street that doesn’t know anything past 11th grade physics.

I know all would say since earth inst loosing energy as the angle of gravitational force and displacement is tangent i.e 90 degrees and as a consequence of equation work is FDcosø Is zero infacr…but we know orbit ...

The person throws a stone of mass 5 kg at 4 m/s horizontally in the north direction. The velocity of the person and the boat after throwing the stone is ? I know it will be on the opposite ...

Will the object’s centripetal acceleration be constant? Or the object ‘s velocity is constant?

I understand that the drag force acting on the feather would be abundant so it would reach terminal velocity soon and thus a = 0 So, apparent weight = m(g-a) = true weight. But what bothers me is ...
