hi, I am 13 years old and i am trying to become a physicist, and I would like to know if this theory of mine is correct or just stupid: Can light speed time dilation be possible, and can it potentially make time travel possible?

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

the answer is 3.1 his answer is wrong mines is right

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
