We are to look for the input work that would yield 50 J when it is only at 65% efficiency. To show this mathematically: Input work  x (65/100) = 50 J. So to find the input work, we are to divide 50 J by (65/100). This is shown below:

Input work = 50 / (65/100) = 76.92 J

Therefore, the input work needed is 76.92 J.

How many mL of water would be displaced by 408 g of lead
Natasha2012 [34]
For this, we must know the density of lead. This is 11.36 grams per cubic centimeter. The mass present is 408 grams. Therefore, the volume occupied will be:
408 / 11.36 = 35.9 cubic centimeters. This is the volume of water that will be displaced.
Now, we know that one cubic centimeter is equivalent to one mL. Therefore,
35.9 ml of water will be displaced.

Which would most likely cause the cylinder head temperature and engine oil temperature gauges to exceed their normal operating r
dusya [7]

Answer: Using fuel that has a lower-than-specified fuel rating.

Explanation:

Most likely, what causes the cylinder head temperature and engine oil temperature gauges to exceed their normal operating ranges is using fuel that has a lower-than-specified fuel rating. This can lead to detonation of the engine which is the tendency for the fuel to pre-ignite or auto-ignite in an engine's combustion chamber.The cylinder head and the engine oil are part of the automobile systems that helps in fuel combustion.
