" During transcription unbinding of DNA by breaking of hydrogen bond takes place by "

A monkey of mass 40kg climbs on a massless rope of breaking strenght 600N . The rope will break if the monkey (Take g =10 m//s^(2) ) .

A monkey of mass 40 kg climbs on a massless rope which can stand a maximum tension of 500 N. In which of the following cases will the rope break? ("Take g"=10m s^(-2))

Two blocks of masses 2 kg and 3kg are connected by a metal wire going over a smoother pulley as shown in figure. The breaking stress of the steel is 2xx10^(9)Nm^(-2) . What would be the minimum radius of the wire used if it not to break ? Take , g=10 ms^(-2)

Two blocks of masses 1 kg and 2kg are connect by a metal wire going over a smooth pulley as shown in figure. The breaking stress of the metal is 2xx10^9m^-2 . What should be the minmum radius of the wire used if it is not to break? Take g=10ms^-2
