Explain why machines are not 100 percent efficient?
because they are not proper
Why aren't machines 100 percent efficient?
becaus ethey have friction
What force stops machines from being 100 percent efficient?
Any mechanical action will waste energy as heat, therefore the work output is always less than the enegry input.
What is the force that prevents all machines from being 100 percent efficient?
Friction is the force that prevents all machines from being 100 percent efficient. It produces a resisting force that hinders the machine's complete functioning. Reducing friction will enhance efficiency.
What are some reason that machines are not 100 percent efficient?
friction and entropy the production of heat with in a system
Are some machines 100 efficient?
false A+
Is a nuclear generator 100 percent efficient?
No, no machine is 100% efficient.
What must take place in order for work to be done?
Energy in some form must be expended, if the machine is 100 percent efficient the work done in Joules will equal the energy input in Joules, but of course machines are never 100 percent efficient, there are always some losses.
How efficient is a small space heater?
it is not very efficientAnswerThey are 100 percent efficient.
Are electric heaters 100 percent efficient?
No. Nothing is 100 percent efficient. In any situation some energy will be given off in a form that is useless to us.
Are turbines 100 percent efficient?
Basically, almost NO physical process is 100% efficient.
When will frictionless engine be 100 percent efficient?
at 0'kelvin
