The diameter of a cooler is 0.3 m and it is filled with a blue liquid to a height of 0.55 m. Then, a can of soda is placed into the cooler that is half filled with water (density of water, p = 1000 kg/m3 ) such that it floats upright in the unknown pink liquid. The can of soda has a mass of 0.020 kg when empty, a diameter of 0.062 m, and its volume is 332 cm^3.Given that the length of the can above the blue liquid is 0.032 m, what is the density of this blue liquid?

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

answer: the correct answer for the fill in the blank is rods.

rods are the specialized photoreceptor cells that are present in the retina of human eye. they are responsible for vision in the night time ( also called scotopic vision). they have very low visual acuity and color distinguishing ability.

as they are responsible for vision in night time, therefore they are found predominantly in the nocturnal animals.
