Two identical rods of same material, transfer a given amount of heat in 16 second, when they are joined in series. If they are joined in parallel, then they will transfer same heat in same condition in time

Surface tension of a liquid is numerically equal to

A homogeneous disc with a radius 0.1 m and mass 4 kg rotates about an axis passing through its centre and perpendicular to the plane in the influence of a tangential force. The angular velocity of the disc as a function of time is given by the formula ω = (4 + 3t) rad/s. The tangential force applied to the rim of the disc is
