When fuel is burned in a cylinder equipped with a piston, the volume expands from 0.245 L to 1.280 L against an external pressure of 1.02 atm . In addition, 843 J is emitted as heat. What is ΔE for the burning of the fuel?

Explanation:

= Pressure =

= Change in volume =

= Emission of heat =

Work done is given by

Total energy of the system

The for the burning of the fuel is .

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:
