Why does the shape of the ramp not affect the Total Energy in the non-friction case and Why does the shape of the ramp affect the Total Energy in the friction case?arrow_forwardConsider the following physical situations. Identify the forces which do work upon the indicated object (in boldface type) and categorize them as conservative or non-conservative forces. Then indicate whether the total mechanical energy of the object changes; it it changes, then indicate whether the change is a positive or negative change. Finally, indicate whether the potential energy and the kinetic energy changes; if PE or KE changes, then indicate whether the change is a positive or negative change.

- A process occurs in which a system's potential energy decreases while the system does work on the environment. Does the system's kinetic energy increase, decrease, or stay the same? Or is there not enough information to tell? Explain. Match the words in the left column to the appropriate blanks in the sentences on the right. positive negative zero unknown ‒‒‒‒‒‒‒‒‒‒ only the potential energy does the work the system does work on the environment Submit the mechanical energy does not change the change in potential energy may be greater as well as less than the work the system does on the environment the body cannot do more work than the change of its potential energy Request Answer The change in kinetic energy is because Reset Helparrow_forwardA 100 kg block is pulled at a constant speed of 5.5 m/s across a horizontal floor by an applied force of 137 N directed 37° above the horizontal.

A The hot water produced from the geothermal wells can be directly circulated through buildings or pumped through a heat exchanger that transfers the heat to a building. B The major regions of geothermal development are in the most volcanically and tectonically active regions of the world. The hot water produced from the geothermal can also be used to produce electricity in a geothermal power plant. Electricity is generated when geothermal heat produces steam that turns turbines on a generator. The energy is accessed through geothermal wells which are drilled into the Earth's crust at approximately a depth of 3 to 10 kilometers. The heat is extracted with a variety of methods but in most cases is drawn from the earth using water and steam. E Geothermal energy production is safe, cheap, and reliable. It provides consistent power generation, poses no risk to the earth, and produces no emissions. F Geothermal refers to producing…arrow_forward
