At S. T.P, one mole of a gas has a mass of 273g if its Volume is tripled because It expands adiabatically, calculate the specific heat capacity at constant volume, (cv), If the constant in T-v relationship is 0.025 Take (Cp) = 1008 jkg k-1 and y = 1.41.

Which surface feature of the moon is characterized by mountainous areas? terrae craters maria regolith

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
