Answer:
D. Because they are using space technology on a shirt so people can wear it on earth as well
Asia is the largest continent.
Answer:
K = ρL²g
Explanation:
Consider L as the length of the raft inside the water when the raft is displaced through additional distance y;
Then:
F = upthrust ( restoring force) = weight of the liquid displaced.

where;
A = L²

F = ky.
Then,


Divide both sides by y
K = ρL²g
Beat frequency is given by the difference of two frequencies played together

given that


Now
