"A reaction in aqueous solution is run in a calorimeter and it is found that the the solution gains 98 kJ of heat and the calorimeter gains 3 kJ of heat. What is the heat gained or lost by the reaction (qrxn) in kJ

Distinguish between a transverse wave and a longitudinal wave.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].

Chameleons catch insects with their tongues, which they can rapidly extend to great lengths. in a typical strike, the chameleon's tongue accelerates at a remarkable 220 m/s2 for 20 ms, then travels at constant speed for another 30 ms.
