<span>An ideal machine is 100% efficient, meaning it puts out all of the energy you put in (ie. no loss due to friction..) A real machine can never be 100% efficient. You must always put more energy Into a real machine than you get out of it.</span>
The efficiency of such a machine<span> is 100%. An </span>ideal machine<span> is one in which no part of the input energy to the </span>machine<span> gets wasted and the whole input energy is converted into the useful work. The efficiency of such a </span>machine<span> is 100%. PLEASE MARK ME AS BRAINLIEST CAUSE IVE NEVER GOT BRAINLIEST BEFORE AND HAVE A GOOD DAY !
