If you see someone moving at a speed close to the speed of light in a train and they walk through the train, would they appear to be moving in slow motion or not?

Yes.

 

[Verify]

Yes.

Lol

Can someone also answer this please?

An alarm clock is set to go off in one hour when at rest. The alarm clock is set in motion at 0.99 times the speed of light
Calculate how long it would take the alarm to go off for the stationary observer watching it move away at 0.99c

Approx. 7 hrs?

Use Time dilation formula.

As they are in the train, and the train is stated as moving at close to the speed of light, they would also appear to be moving at close to the speed of light. So no. Unless of course you mean relative to the motion of the train.
