Assignment:
Answer the following questions:
1. What is the value (in km/s/Mpc) of your estimate of the Hubble constant?
2. What is the relationship between the value of the Hubble constant and the speed at which the universe is expanding?
3. Search on Hubble constant on Wikipedia. There is a graph that shows values of the Hubble constant as determined by various researchers over the past 20 years or so. Describe how your value fits in with these values. It is surprising that even a crude method of distance determination such as we used here results in a value of H0 that is still in the ball park.
4. What is meant by the Hubble time, tH ? Calculate tH for your measured value of the Hubble constant.
The air table is approximately 25 cm squared. If the incline has a rise of 1 cm over the distance, what is the maximum velocity up the slope
Determine the acceleration of the system and the tension in the string if the coefficient of friction between A and the table is 0.75.

An electrophoresis experiment is performed on two fragments of DNA with radius r1 = 16 nm and charge q1 = -7e, and r2 = 29 nm. What is the charge on the larger fragment
It is observed that the stone bounces back at 10 m/s and that the block compresses the spring by 4.0 cm. You are dealing here with an inelastic collision (when total momentum is conserved) followed by a spring compression (when mechanical energy i..
Two disks are rotating about the same axis. Disk A has a moment of inertia of 5.28 kg·m2 and an angular velocity of +4.29 rad/s. Disk B is rotating.
A circular racetrack with 250 m radius lies in the x-y plane and is centered at the origin. A car rounds the track counterclockwise starting at the point (250 m , 0). Find the total distance traveled after one-quarter lap.
