Which is a drawback of solar energy

A spherical gas container made of steel has a (n) 17-ft outer diameter and a wall thickness of 0.375 in. Knowing that the internal pressure is 60 psi, determine the maximum normal stress and the maximum shearing stress in the container.

An inclined rectangular sluice gate AB 1.2 m by 5 m size as shown in Fig. Q3 is installed to control the discharge of water. The end A is hinged. Determine the force normal to the gate applied at B to open it.

When a gas in a piston cylinder device is compressed, and as a result temperature rises. This process is a work interaction. a) True b) False

1.5 kg of liquid water initially at 12∘C is to be heated to 95∘C in a teapot equipped with an 800-W electric heating element inside. The specific heat of water can be taken to be 4.

Write a simple phonebook program that reads in a series of name-number pairs from the user (that is, name and number on one line separated by whitespace) and stores them in a Map from Strings to Integers.

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.

hypothetical A-B alloy of composition 40 wt% B-60 wt% A at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively.
