According to the first law of thermodynamics, the change in thermal energy of an object is equal to the heat added to the object divided by the work done by the object. t f

Aseries circuit consists of a resistor with r = 20 ? , a capacitor with c = 0.01 f, and a decaying battery with e = 300e? 5t. if the initial charge is 0, find the charge as a function of time t

Apackage of supplies is dropped from a plane, and one second later a second package is dropped. neglecting air resistance, the relative velocity of the 1st package viewed from the second will 56) a) increase. b) be constant. c) be zero. d) depend upon their weight. e) decrease

The ability to make things happen is also called a. heat b. force c. matter d. energy
