Hello, may I get a step-by-step explanation for each? Thank you!

An FM radio station broadcasts at a frequency of 101 MHZ. The power radiated from the antenna is. 50 kW. How many photons per second does the antenna emit? 1P In the lungs there are tiny sacs of air. which are called alveoli. An oxygen molecule [mass = 5.30 x 1025 kg} is trapped within a sac, and the uncertainty in its position is 0.110 mm. What is the minimum uncertainty in the velocity of this oxygen molecule? Number n Units 1P An owl has good night vision because its eyes can detect a light intensity as small as 5.0 X 10"13 me2. What is the minimum number of photons per second that an owl eye can detect if its pupil has a diameter of 3.3 mm and the light has a wavelength of 545 nm? Number I Units 1
