Aslender rod is 80.0 cm long and has mass 0.290 kg. a small 0.0200 kg sphere is welded to one end of the rod, and a small 0.0500 kg sphere is welded to the other end. the rod, pivoting about a stationary, frictionless axis at its center, is held horizontal and released from rest. what is the linear speed of the 0.0500 kg sphere as it passes through its lowest point?

V= 1.2m/s

Explanation:

Since both spheres fall to an equidistant center, both spheres travel a distance of 0.4m

This is:

The 0.05kg sphere falls 0.4m while the 0.02kg sphere goes up 0.4m

The decrease in Potential Energy is given by:

The moment of inertia for the entire system is given by:

In this way the kinetic energy is given by

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
