a train travels on a track at constant velocity of 100 km/h inside one of the train cars is a table and a book the table and the book are moving with the train at constant velocity however the table in the book are at rest ( stationary) relative to each other using Newton's third law of motion what is the force relationship between the table and the book doesn't matter that the train is moving?

Distinguish between a transverse wave and a longitudinal wave.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

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?
