A clothes dryer is spinning at 75 rpm.A student opens its door and it comes to rest after rotating through four revolutions.Assume constant deceleration.What was the magnitude of the dryers angular deceleration asked by hard on march 23, 2011 physics.
A person consumes food as a means of producing thermal energy so that the body can perform work.To lose weight, a person would need to a.Consume more calories of food energy than the number of calories of work performed.
The drum of a clothes dryer turns at 635 revmin.If the door to the dryer is opened, the motor is turned off.If the drum requires 8.0 s to slow to a stop, what is the angular acceleration of the drum.
Kinetic energy harvesting involves conversion of mechanical energy into electrical energy, wherein environmental displacements kinetic energy source are coupled with a transduction mechanism.In these systems, a mechanical component is attached to an inertial frame, which serves as a fixed reference as depicted in figure 5.
Other things which could be meant by specifying the energy of a particle are its total energy e total mc 2 1vc 2, where v is its velocity, or its kinetic energy, ke totalmc 2.Question im not a physicist or mathematician, but could there be a better explanation to the expansion of the universe without assuming so much dark matter.

15 where summations apply to inflows i and outflows o, and where other types of energy terms, such as kinetic and potential energy flows, are assumed negligible.For clarity, the figure shows only one port in and one port out.Kinetic and potential energy terms may be added analogous to the enthalpy termsat each port, if needed.
6.4 drag force and terminal speed.Drag forces acting on an object moving in a fluid oppose the motion.For larger objects such as a baseball moving at a velocity in air, the drag force is determined using the drag coefficient typical values are given in table 6.2, the area of the object facing the fluid, and the fluid density.For small objects such as a bacterium moving in a denser.
A wind turbine is a machine that converts the winds kinetic energy into rotary mechanical energy, which is then used to do work.In more advanced models, the rotational energy is converted into electricity, the most versatile form of energy, by using a generator.
Clothes dryers are among the biggest energy hogs of all our appliances because so much of the energy goes out the exhaust or heats up the dryer drum or just leaks away in some other way.When i started hanging out my clothes instead of putting them in the dryer.
