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!

Alina [70]

In order to survive, all living things need air, water, and food. Animals obtain their food from plants and other animals, which provides them with the energy they need to move and grow. An animal's home must provide these basic needs along with shelter from bad weather and predators.

What is the Difference between DNA & RNA?

Travka [436]

DNA is deoxyribonucleic acid while RNA is ribonucleic acid !

DNA has base pair of adenine guanine thymine and cytosine.....while RNA has adenine guanine cytosine and uracil !

DNA is always double helix while RNA is mainly single helix !

DNA contains genetic info for 99℅ of organism while RNA is being catalytic and unstable than DNA is only present as genetic information holder in 1℅ !

DNA does not involve in protein synthesis directly but RNA has to !

for more difference, comment !

The product of 279 and which number has three decimal places?<br>1.4<br>2.741<br>32.4<br>72.43

maxonik [38]

2.741

Explanation:

The product of 279 and 2.741 will give an answer in three decimal places.

This is because, the number 2.741 is already in three decimal places.

A product between two decimal numbers will give an answer to the number with the highest decimal places.

1.4 x 279 = 1 decimal place
