The efficiency of a car’s engine is 14 percent. This implies that the engine wastes

Biology
1 answer:
Harlamova29_29 [7]3 years ago
7 0

Answer:

C) 86 J of energy for every 100 J that enter it.  

Explanation:

Efficiency is a measure of performance of an engine which can be calculated by the formula as given below to get in percentage:

           Efficiency = energy output/energy input x 100

If the efficiency of a car’s engine is 14 percent it means that for every 100 joules of energy that is entered into it, only 14 joule is converted into useful output and rest of the 86 Joules is wasted.

The efficiency of any machine is never 100%, however, if any machine miraculously converts all the input energy to useful output energy, it means it is 100% efficient.

Hope it helps!

This has to do with blind spots: What parts of the eye are involved with this inability to see? How do these eye parts function?
Slav-nsk [51]

Answer:

  • Blindspot
  • It has a vital role. It is the only way out of the optic nerve. By this hole optic nerve exits from the eye and goes towards the brain.
  • It can be proved by a simple experiment. A paper sheet is taken. Then a cross and a circle are drawn side by side on that paper. Then we will focus on the cross. Then by closing one eye and by bringing the paper slowly towards our face, the circle will be disappeared at a certain point.        

Explanation:  

The blind spot is a region on the retina where ganglion cells connect with the optic nerve, and the optic nerve and blood vessels leave the eyeball. There are no receptors in this area so nothing can be translated into vision. That's why the blind spot is unable to see things.
