-
- height of the man +length of the chain
- 10 years agoHelpfull: Yes(19) No(9)
- let the height of chain from ceiling = x
let the height of man = y
the height of man's hand to reach the chain above his head=z
then
height of ceiling=x+y+z - 10 years agoHelpfull: Yes(8) No(5)
- oscillate chain,calculate the timeperiod for one complete oscillation by SHM.
put in T=2*pi*(L/G)^1/2 so,L=length of chain and L + man's height=rooms height. - 10 years agoHelpfull: Yes(3) No(0)
- room is different from the one in which chain is hanging

- let the height of man be =6 ft
and the length of chain would be=x
now height of room= y
therefore y=6+x ft - 10 years agoHelpfull: Yes(2) No(18)
- let the height of the man be"x"...
height of the chain from ceiling is "y"
so obviously height of the room will be...length of chain and length of man
i..e,,x+y - 10 years agoHelpfull: Yes(1) No(6)
