If u connect 3 resistors, having values 2ohm, 3ohm, 5ohm in parallel, will the value of total resistance of will be 2ohm or greater than 5ohm or lie between 2ohm and 5oh? explain

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
