During testing, the engine runs at 180 revolutions per minute (rpm) with a pressure-volume indicator diagram showing a mean net area of 3.4 cm2 and a diagram length of 1.2 cm. The pressure scale on the indictor diagram is set to 150 kN/m2 per cm. Calculate the mean effective pressure (m.e.p) and the indicated power developed by this four-cylinder four-stroke engine.with clear solution please

In order for the hot air balloon to rise into the sky, it must be heated to 120°C. Once the balloon is up in the air, the air needs to be cooled in order for the balloon to land. If the temperature of the balloon is decreased to 40.0°C, what will the new volume of the gas be? Remember to pay close attention to the units of temperature before beginning your calculations.

- Kayla began a science experiment with 18 grams of an unknown solid. During the experiment, the change in the mass of the solid was – 7 grams. What was the mass of the solid at the end of the experiment? To solve the problem, Edna subtracted 18 – ( – 7 ) and came up with an answer of 25 grams. Is Edna correct? Why or why not? Yes, Edna is correct. No. The answer should have been – 25 grams, not 25 grams, because the mass of the solid decreased. No. Edna should have added 18 + ( – 7 ) because she needed to add the initial mass and the change in mass.
