Which of the statements about the mechanism of muscle contraction are correct? I. acetylcholine is released when the neural signal reaches the motor end plate II. muscle contraction is initiated by a signal sent by CNS via a sensory neurone III. during muscle contraction, isotropic band gets elongated. IV. repeated activation of the muscles can lead to lactic acid accumulation.

A heating element of resistance r is fitted inside an adiabatic cylinder which carries a frictionless piston of mass in and cross-section A as shown in diagram. The cylinder contains one mole of an ideal diatomic gas. The current flows through the element such that the temperature rises with time t as DeltaT = alphat + 1/2beta t^2 ( alpha and beta are constants), while pressure remains constant. The atmospheric pressure above the piston is P_0 . Then the rate of increase in internal energy is 5/2 R (alpha + beta t) the current flowing in the element is sqrt(5/(2r)(alpha +betat)) the piston moves upwards with constant acceleration the piston moves upwards with constant speed
