For the following homework problems please show all of your work.
1. If the energy of a photon is given by the equation E = hv, where
h is known as Planck's constant, and has the value of h = 4.136 x
10-15 eV -s, then complete the following table. Please note: the unit
called an electron volt (eV) is a unit of energy whose value is compa-
rable to the values seen in atomic transitions, and a Hertz is Hz = 1/s.

An object is propelled off of a platform that is 75 feet high at a speed of 45 feet per second (ft./s). The height of the object off the ground is given by the formula h(t) = - 16t+45t+75, where h(t) is the object's height at time (t) seconds after the -16 object is propelled. The downward negative pull on the object is represented by Solve for t.arrow_forward
