How much heat is absorbed when a 2.00 x 102 g sample of water at 60.0°C is heated to steam at 140.0°C? Q = mCwaterT+ mH, + mСsteamT (Water = 4180 J/(kg •K) H, =
(2.26x10J/kg)
Steam = (2020 J/(kg .K))

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
