Answer:
C. Tag the hummingbirds with transmitters and track their movement.
Explanation:
Hypothesis refers to the conclusion of the analysis found on the grounds of certain observations. The hypothesis is further tested and verified by performing certain experiments. In the given excerpt, Juan hypothesizes that certain group of hummingbirds fly to certain locations depending upon the season. To test the hypothesis, Juan can experiment with finding and tracking the hummingbirds and the direction in which they fly. Tagging the hummingbirds with transmitters and tracking their movement would help Juan concluding about the hypothesis.
Answer: a) -3.5m b) 0.22man
Explanation:
a) A near sighted person is a person that can only see near objects clearly but not far objects.
According to the lens formula
1/u+1/v = 1/f
where u = object distance (distance between the object and the lens)
v = image distance (distance between the image and the lens)
f = focal length of the lens
Given u= infinity v = 3.5m f= ?
1/f = 1/infinity +1/3.5
Since the lens used for correcting near sighted person is concave lens therefore the image distance is negative due to virtual image produced by the lens.
We then have 1/f1 = 1/infinity -1/3.5
f1 = -3.5m
b) A far sighted person is a person that can only see far objects clearly but not near objects.
According to the lens formula
1/u+1/v = 1/f
Given u= 0.35m v = 0.6m f2= ?
1/f2 = 1/0.35 + 1/0.6
Since the lens used for correcting far sighted person is convex lens therefore the image distance is positive due to mostly real image produced by the lens (reason why the image distance is positive.
f2 = 0.22m

Answer:
These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward
