A simple pendulum is suspended from the ceiling by means of a string and this time, the pendulum is 2.40 m long and has a mass of 3.23 kg. You give it a push away from vertical so that it starts swinging with a speed of 2.93 m/s. Due to friction at the pivot point, 1.00 Joule of the pendulum s initial kinetic energy is lost as heat during the upward swing. What maximum angle will it reach, with respect to the vertical, before falling back down?     39.5 degrees     33.8 degrees     35.1 degrees     43.9 degrees

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.
