A gas inside a piston-cylinder assembly expands from P, = 6.5 bar, V, = 0.012 m³ to P2 = 3.3 bar in a process during which the relation between pressure and volume is pV1.3 = %3D constant. The mass of the gas is 0.12 kg. The specific internal energy of the gas decreases by 4 kJ/kg during the process. Considering the gas as the system, with negligible changes in kinetic and potential energy, solve the problem and determine the heat transfer to/from the gas, in kJ. Provide four (4) decimal places when rounding off What is the area of the piston face in the problem above, if the piston rises by 80mm after the expansion?

We have four metal spheres made of iron. The spheres are about the size of a snowball and all the same size. We also have 4 different slides. The slides are numbered and all of them are numbered in the picture. The shape of these 4 slides is as in the picture. We drop our metal spheres from the top of 4 slides at the same time. On which slide will the ball dropped first arrive at the target point below? IRON BALL 4 AIM
Help!!! Please answer all Correctly!!! Please
Please help. Written on paper not typed on computer or keyboard please. Need help on all questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.
A suspended date that's able to pivot from the top seperates two liquids. There is a stopper that prevents the gate opening anti-clockwise. The gate has a height of 0.5m. The liquid on the right is twice as dense as the liquid on the left. The liquid on the left has a depth of 0.3m. 1) What is the minimum depth of liquid on the right for the gate to open. 2) Comment on the ability to solve this question if the liquid on the left was 1m (filled to the top)

Question 20 of 20 < A Water Balloon Battle. You are launching water balloons at a rival team using a large slingshot. The other team is set up on the opposite side of a flat-topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 100 mph at angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the building), you plan to splash the other team by making a balloon explode on the ground near them. If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a) magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical speed)?
