As the elevator begins to move upward, the reading on the scale will increase due to the increase in apparent weight experienced by the person inside the elevator. This increase is a result of the combination of the person's actual weight and the upward acceleration of the elevator.
As the elevator begins to move upward, the reading on the scale will momentarily increase. Conversely, as the elevator starts to move downward, the reading on the scale will momentarily decrease. This change in reading is due to the acceleration experienced by the occupants of the elevator, causing a shift in apparent weight.
Your weight (the force you feel at the soles of your feet) in an elevator traveling at any constant speed in anydirection would be the same at any instant as it would be if you were in that elevator in the same place, stopped. For practical purposes, it would be the same as it would be when you're standing on the ground. Technically, weight changes with altitude, but for any existing building the difference between your weight at the lowest and highest points of the building will be so slight as to be undetectable. You'd probably lose more weight due to evaporation of moisture in perspiration and exhaled breath during the elevator ride than you would due to the slight reduction in gravity resulting from your moving a bit further from the surface of the Earth.In order for your perceived weight to change, there has to be an acceleration. Constant speed/velocity is not acceleration. You would feel a change in weight as the elevator slowed down or sped up, but you would feel your "normal" weight once the elevator reaches constant speed/velocity.
The elevator stops and a person talks to you
step away from the door
It breaks, and you fall and die
It melts them slowly, drop by drop. Although this usually is more apparent on trees, it weathers the stone/plaster/building material. It usually isn't that apparent because buildings are so huge when put in comparison with the damage caused by acid rain, but it happens.
An event that happens without apparent cause.
the elevator for the hub starts to work
I assume you mean, the cables that sustain the elevator break.The coin will maintain its relative movement relative to the elevator. For example, if at the moment the elevator disconnects the coin is moving upward at 1 m/s (with respect to the elevator), it will continue going upward at the same speed (once again, with respect to the elevator), until it hits the ceiling. This is because both the elevator and the coin will accelerate downward at the same rate.
If an elevator is falling and you jump inside, you will still be moving at the same speed as the elevator. Jumping will not change the outcome of the fall. It is safer to brace yourself and try to protect your head and body during the fall.
As the elevator moves upward, the reading on the scale will temporarily increase. This is because the scale measures the force exerted by the person standing on it, which includes their weight and an additional force due to the upward acceleration of the elevator.
