Consider two massless springs connected in parallel. springs 1 and 2 have spring constants k1 and k2 and are connected via a thin, vertical rod. a constant force of magnitude f is being exerted on the rod. the rod remains perpendicular to the direction of the applied force so that the springs are extended by the same amount. find the effective spring constant k of the two-spring system. give your answer for the effective spring constant in terms of k1 and k2.

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?
