The unified atomic mass unit, denoted u, is defined to be 1u = 1.6605 × 10^-27 kg. It can be used as an approximation for the average mass of a nucleon in a nucleus, taking the binding energy into account. How much energy would you obtain if you completely converted a nucleus of 14 nucleons into free energy?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

How can you increase the strength of an electromagnet?

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
