At a depth of 4 miles in the ocean the ppressure is 9520 psia. Assume that the specific weight at the surface is 64.0 lb/ft^3 and that the average volume modulus is 320000psi for the pressure range. answer the following,
a)What will be the change in density at that depth?
b)What will be the specific volume at that depth?
c)What will be the specific weight at that depth?
d)What is the percentage change in the specific weight?
Two carts with masses of 4.72 kg and 2.84 kg move toward each other on a frictionless track with speeds of 4.86 m/s and 3.97 m/s respectively. The carts stick together after colliding head-on. Find the final speed.
