1. A uniform pressure of 5.7 × 10⁵ N/m² is applied to all six sides of a copper cube. What is the percentage change in volume of the cube?

2. A liquid (p = 1.65 g/cm³ ) flows through a horizontal pipe of varying cross-section as in Figure. In the first section, the cross-sectional area is 10.0 cm² , the flow speed is 275 cm/s, and the pressure is 1.20 x 10⁵ Pa. In the second section, the cross-sectional area is 2.50 cm² . Calculate the smaller section’s (a) flow speed and (b) pressure.

3. A hydraulic lift raises a 2 000-kg automobile when a 500-N force is applied to the smaller piston. If the smaller piston has an area of 10 cm² , what is the cross-sectional area of the larger piston?

Consider a spherical tank of air originally at atmospheric pressure (1.013*105 N/m2). Air is being supplied at a uniform velocity of 2 m/s through a tube of diameter 2 cm. The tanks diameter is 1m. The inlet pressure is maintained at 3*105 N/m2 and the temperature of the tank and inlet pipe is 300K. Determine the time required for the pressure in the tank to reach 2*105 N/m2.

Python Please An n-sided regular polygon has all its sides of the same length and all its angles of the same degree. It is also called an equilateral and equiangular polygon. In this activity, you will design a class named RegularPolygon that contains: A private int data attribute named n that defines the number of sides of the polygon. A private float attribute named side that stores the length of the side. The constructor ( __init__ method) that creates a...
