Answer:
36 N
Explanation:
Velocity of a standing wave in a stretched string is:
v = √(T/ρ),
where T is the tension and ρ is the mass per unit length.
300 m/s = √(T / 4×10⁻⁴ kg/m)
T = 36 N

Answer:
7.5 m/s
Explanation:
We can find its velocity when it reaches the buoy by applying one of Newton's equations of motion:

where v = final velocity
u = initial velocity
a = acceleration
s = distance traveled
From the question:
u = 28 m/s
a = -4 
s = 91 m
Therefore:

The velocity of the boat when it reaches the buoy is 7.5 m/s.
Answer:
B. True since when a person removes the weights there is less for the other people
Explanation:
This problem ask us consider some things
In the private current it is considered a good example of a private good
the fish in the river are a common resource
the fishing in the river is tragedy of the commons
A False. The fish in the river are natural and not sown
B. True since when a person removes the weights there is less for the other people
C. False. Some fishermen will go to the creek
D. False some will go to the river
.
Because over land they wont be cooled by the water, and the deeper water is, the colder it is.
