practice problem 1. Two related problems…. Determine the mass of Earth's atmosphere using the value of the standard atmosphere. Determine the scale height of Earth's atmosphere — the height the atmosphere would have if its density stayed constant instead of decreasing with altitude.
PRESSURE, FORCE AND AREA – PRACTICE QUESTIONS CALCULATOR ALLOWED 1. Find the pressure exerted by a force of 600 Newtons on an area of 30 m2. Give your answer in N/m2. 2. An object is placed on a floor. The area of the object in contact with the floor is 3 m2. The pressure exerted by the object is 15 N/m2.
12 lip 2024 · What is Pressure Formula? The pressure formula, crucial in physics, quantifies the force per unit area applied to a surface and is expressed as. 𝑃 = 𝐹 x 𝐴. 𝑃 represents pressure. 𝐹 the applied force. 𝐴 the area involved.
How did you do? View answer. 1b 7 marks. Using information from the table in (a): (i) Calculate the weight of the elephant. weight = ..................................................... N [3] (ii) Calculate the pressure the elephant exerts on the ground when it is standing on four feet. Include a unit.
The pressure is coming 100 kPa from the air above him, and 100 kPa from the water above him. At 20 m, the total pressure on him is 300 kPa, and so on. WORKED EXAMPLE An aquarium in a 'sea life' centre has a tunnel through a tank of water at a depth of 5 m below the surface.
Example 1: Calculating Pressure. A force of 150 N is being applied over an area measuring 0.5 m ^2. Calculate the pressure on the object ensuring you give the correct units. [2 marks] We’re looking for pressure, so constructing the triangle and covering up the p, we must divide the force by the area. So.
5 lip 2024 · Pressure is defined as. The concentration of a force or the force per unit area. Pressure, force and area are related by the equation: Where: P = pressure, measured in pascals (Pa) F = force, measured in newtons (N) A = cross-sectional area, measured in metres squared (m 2)
