Asmall ball is attached to one end of a spring that has an unstrained length of 0.169 m. the spring is held by the other end, and the ball is whirled around in a horizontal circle at a speed of 3.15 m/s. the spring remains nearly parallel to the ground during the motion and is observed to stretch by 0.0131 m. by how much would the spring stretch if it were attached to the ceiling and the ball allowed to hang straight down, motionless?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
