What else can I help you with?
Can solar energy be changed into thermal energy without any work being done?
Yes, solar energy can be converted into thermal energy passively through techniques like solar water heaters or concentrating solar power systems. These systems absorb sunlight and directly generate heat without the need for mechanical work.
How can energy be consumed when no work is done?
Energy can be consumed in the form of heat, light, or sound without any physical work being done. For example, a light bulb consumes electrical energy and emits light without performing any mechanical work. In such cases, the energy is being transformed from one form to another without necessarily producing external work.
You can detect energy only by the effect it has on matter?
You are made from matter, and therefore would not be able to detect energy without it having an effect on you. Energy is defined as the capacity for doing work. Without work ever being done on matter, and without energy ever being defined this way, energy would not be detected.
How do you know work is being done?
work is being done when you use energy
What is being done to conserve energy?
J
Can the catalytic converters be changed without going to the dealership to have it done?
YesYes
Why can't kinetic energy ever be greater then potential energy?
In a closed system without external forces, the total mechanical energy (which is the sum of kinetic and potential energy) remains constant. Kinetic energy represents the energy of motion, while potential energy is associated with an object's position or state. The total energy of an object or system cannot exceed its initial energy without external work being done to increase it.
What has computers done to surpermarket?
computers have done alot other the past 15 years it changed everything and what it has done is made alot of people without a job because people now use the internet and buy there shopping on it. It has changed the world
When work is done on a object the object gains energy?
Yes, when work is done on an object, energy is transferred to the object. This can result in an increase in the object's kinetic energy, potential energy, or both, depending on the nature of the work being done.
Can the total energy of an object change without any work being done Explain?
Energy is a conserved quantity. That means that, if no energy enters or leaves an object, the total energy of this object will remain the same. There are several ways for energy to enter or leave; I am not sure whether all of these qualify as "work".
How long should a car ignition switch last after being changed?
Done correctly, indefinitely.
When negative work is being done what happens to potential energy?
Negative work increases potential energy.
