By how much does the statue compress the stand
A 3500 kg statue is placed on top of a cylindrical concrete (Y = 2.3 x 1010N/m2) stand. The stand has a cross sectional area of 7.3 x 10-2m2 and a height of 1.8 m. By how much does the statue compress the stand?

In what ways do photons resemble other particles such as electrons? In what ways do they differ? Do photons have mass? Do they have electric charge? Can they be accelerated? What mechanical properties they have?
Two light bulbs, one rated 50 W and a second rated 100 W are both supposed to be connected to a 110 V source of emf. Which of the following is true?
An alpha particle has a charge of +3.2 x 10 ^ -19 C and a mass of 6.6 x 10 ^ -27 kg. The angle between v and B is 51 degrees. What is the radius of its circular orbit?
In reaching her destination, a backpacker walks with an average velocity of 1.30 m/s, due west. This average velocity results because she hikes for 6.44 km with an average velocity of 2.58 m/s, due west, turns around, and hikes with an average vel
A spelunker enters a cave. Consider the entrance to the cave the origin. the spelunker then moves east for 100 ft, then moves 100 ft at 60 degrees North of West before finally moving 100 ft at 30 degrees South of West.
A physicist out at the cabin uses a sonar device to determine the speed of a jet-ski on the nearby pond. A 20.5 kHz signal is sent out and a 22.5 kHz signal is returned. Assume the speed of sound in air is 340 m/s. How fast is the jet-ski moving?
The air then expands at constant temperature to a pressure of 0.4 MPa. Assume the process occurs slowly enough that the acceleration of the piston can be neglected. The ambient pressure is 101.325 kPa. A) Determine the work (kJ) performed by the a
Each of whose components is an independent, random variable distributed as a Gaussian distribution with variance (sigma)^2. That is, let u denote the length of v and find P(u)du. Graph your answer, try various values of sigma.
What is the mass of the container? Ignore the mass of the balloon and the air within it. Do not neglect the buoyant force exerted on the shipping container by the water. The density of seawater is 1025 kg/m3.
Air enters an isentropic turbine at 145 psia and 900F through a 0.52 f^2 area with a velocity of 595 ft/s. It leaves at 15 psia with a velocity of 95 ft/s. Calculate the air temperature at the turbine exit AND the power produced by this turbine.
