Two rods are made of the same kind of steel. The longer rod has a greater diameter. A force of magnitude F is applied to each end of each rod. Compared to the rod of length L, the rod of length 2L has:

When recording data in the lab, which of the following should you NOT do?

A yo-yo is placed on a horizontal surface as shown. There is sufficient friction for the yo-yo to roll without slipping. If the string is pulled straight up as shown with a force of constant magnitude F:

Three force vectors are shown in the figure. All three forces act at point P. Rank the three forces in order of the magnitude of the torque that they produce about point O, a distance r = 0.500 m from point P. Rank them from largest torque to smallest torque.

You want to double the radius of a rotating solid sphere while keeping its kinetic energy constant. (The mass does not change.) To do this, the final angular velocity of the sphere must be:

The graph shows the angular velocity omega (z) and angular acceleration alpha (z) versus time t for a rotating body. At which of the following times is the rotation speeding up at the greatest rate?  

An incompressible fluid with zero viscosity flows through a pipe of varying radius (shown in cross-section). Compared to the fluid at point P, the fluid at point Q has:

If you titrate 25.00mL of NaOH (unknown concentration) with 35.74mL of 1.00M HCl, what is the molarity of the NaOH?

(2 points) What is the name of the lab glassware shown below?

What is the precipitate in the following reaction?  AgNO3(aq) + NaCl(aq) –> ?
