1. suppose that you have two boxes one is 20 cm X 20 X 20 cm. The other is 20cm X 20 cm X 40 cm. a.) how does the pressure of the air on the outside of the two boxes compare?
b.) How does the magnitude of the total force of the air on two boxes compare?

2. In a certain internal combustion engine 0.0021 m^3 of the air at atmospheric pressure and 303 K is rapidly compressed to a pressure of 20.1 x 10^5 Pa and volume of 0.0003 m^3 what is the final temperature of the compressed gas?

3.) A tank truck takes a load of 45,725 L of gasoline in houstin where temp is 28.0 C the truck delivers its load in minneapolis where the temp is -12.0C
a.) how many liters of gas does the truck deliver
b.) what happened to the gas?

please help me answer one of these or all if you can its due tmro thank you so much

Polly is pushing a box across the floor with a force of 30 n. the force of gravity is –8 n, and the normal force is 8 n. which value could describe the force of friction if polly could not move the box?

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
