How does the shell model predict 7- 2 for the ground state spin parity of 41 20Ca. What does the model predict about the spin and parities of the ground states of 30 14Si and 14 7 N?
A mass of 1.62 kg stretches a vertical spring 0.328 m. If the spring is stretched an additional 0.136 m and released, how long does it take to reach the (new) equilibrium position again.
Sucrose is allowed to diffuse along 8.0 cm length of tubing filled with water. The tube is 5.6 cm^2 in cross-sectional area. The diffusion coefficient is equal to 5.0*10^-10 m^2/s, and 8.0* 10^-14 kg is transported along the tube in 19 s. What is the..
