What is the solution for all parts of given problem:
Problem: If a solid sphere of some material has a diameter of 15 in. and weighs 2 lb,
Part A: What is the specific weight of the material?
Part B: What percent of the sphere's volume extends above the surface if placed in a vat of water?
I want you to explain the physics in this problem.
In a Carnot cycle, the isothermal expansion of an ideal gas takes place at 400K, determine the work performed by the gas during the cycle
Gas is confined in a tank at a pressure of 12.6 atm and a temperature of 23.0°C. what is the pressure of the gas remaining in the tank
A swimmer swims north at .35 m/s relative to still water across a river that flows at a rate of .15 m/s from west to east. Calculate the direction of swimmer's velocity relative to the riverbank
a particle of rest mass mo with kinetic energy 15moc2 makes a perfectly inelastic collision with an identical particle
A little study of energy conservation tells us that the gain in KE of the ball as it rolls down the ramp is equal to the decrease in PE as the ball loses height-in short, APE = AKE. Why were we able to bypass KE in our analysis here
A helicopter is ascending vertically with a speed of 9 m/s. At a height of 200 m above the Earth, a package is dropped from a window. How much time does it take for the package to reach ground.
An airplane propeller is 2.08 m in length (from tip to tip)with mass 117 kg. The propeller is rotating at 2400 rev/min aboutan axis through its center. What is its rotational kinetic energy
A 120.0-\Omega resistor, a 60.0-\Omega resistor, and a 40.0-\Omega resistor are connected in parallel and placed across a 12.0-V battery. What is the equivalent resistance of the parallel circuit? What is the current during the entire circuit?
What is the magnetic field strength. Consider a ladder 5 meters tall, and a 150 kg weight on top of it. The ladder is leaning against the wall.
What are the main problems which super symmetry purports to solve? Where would LHC-disconfirmation of SUSY leave String Theory? What would constitute lack of evidence for SUSY at the proposed LHC energy scales (e.g. certain predicted super partners a..
