While standing on a lakeside pier, you see a fish in the water and decide to try some less common methods of snagging dinner. If you try to snag the fish with a harpoon, where should you aim? Directly toward where you see the fish. Below where you see the fish. Above where you see the fish? Where should you aim if you instead use a high-powered laser to zap the fish? Directly toward where you see the fish. Below...

3) Hexagon aquarium is filled up 10 cm from the table. Each side of the aquarium is 5.0 cm and the distance between 1 corner and the other directly across from it (going through the aquarium) is 10.0cm. The base of the base is 0.50 cm thick and the walls are 0.25cm thick. What is the volume of water contained in the aquarium?

As you’re sitting watching your goldfish in their tank, you notice a thick biofilm on the glass walls of the aquarium, and decide you want to study it. You find that the biofilm started with Pseudomonas bacteria, and grew from there. A. The water looks pretty clear, but you know there must be pseudomonas and other bacteria in the tank.Explain two ways by which you could titer the planktonic bacteria in the water B. you try to add a metabolic...

You are looking, from directly above, at a goldfish at the bottom of a 54.0-cm fish tank filled with water. How far away does the fish look to you? The index of refraction of water is 1.34. A beam of light is incident, from air, on a flat surface of glass (n=1.50). The refracted ray inside the glass is found to make an angel of 26.7° with the direction of the incident ray. Calculate the angle of incident.

A laser is shot into an aquarium filled with water as shown in the picture given on your paper worksheet. The laser light enters the aquarium 15 cm from the top of the water and first enters a 1 cm thick piece of glass (n 1.61) before it enters the water (n 1.33). The inside dimensions of the aquarium are 60 cm (wide) and 40 cm (tall). Find the location at which the light exits the aquarium. (Figure 1) Correct...

#3 Suppose you have a fish tank made of a plastic polymer that has a mirror on the bottom. The fish tank is exactly half full of water. The fish tank is lit by a light coming from the upper, left hand corner, which you can approximate as a ray of light traveling at 45 degrees from the normal towards the water. For fun you put a mirror on the top of the tank as well. A) Draw the transmitted...
