Solution
The text you provided seems to be a set of physics problems. Here are the solutions:
-
The force exerted by the air inside the tyre can be calculated using the formula: Force = Pressure x Area. So, the force is 200,000 Pa (since 1 kPa = 1,000 Pa) x 0.1 m^2 = 20,000 N. So, the correct answer is 20,000 N.
-
The pressure of a gas is inversely proportional to its volume (assuming the temperature and the amount of gas are constant). This is known as Boyle's law. So, pulling the piston outwards (increasing the volume of the container) will cause the pressure to decrease.
-
The total pressure experienced by the submarine at a depth of 100 meters is the sum of the atmospheric pressure at the surface and the pressure due to the weight of the seawater above it. The pressure due to the seawater can be calculated using the formula: Pressure = Density x g x Height. So, the pressure due to the seawater is 1,030 kg/m^3 x 10 N/kg x 100 m = 1,030,000 Pa. Adding the atmospheric pressure at the surface (100,000 Pa), the total pressure is 1,130,000 Pa. So, the correct answer is 1,130,000 Pa.
