which is better machatronics or nano technology? in your opinion somebody?

i got the speed of 342.8 m/s

yes i am in a denser medium, water looking to a less dense, air i calculated and got 48.6 degrees and i think the distance is 5.1 metres for the first question i need to hear the guy warning me of the water balloon in order to avoid it but then i need to know if the guy's warning can...

also i don't know how the distance to the pool (4.5) will help me find how deep i must be to find or see the total internal reflection another thing is that i tried doing the first question and i tried using the Speed of Sound in Air formula v= 331+ 0.59 Tc

in the text there is a very similar question to the first one i have posted but it doesn't show you how to get it just the answer and the second question in the text i can only find information on the total internal reflection the two conditions required for total internal reflection...
