Answer:
The amount of the sun energy that could be collected.
Explanation:
Some limitations are, the amount of the sun's energy that could be collected the radiation of sun is nearly fixed. The place where we can put the solar panels are also limited.
It would be 2000N ( newtons )
Answer:
5.03 m
Explanation:
The wavelength of a wave is given by
where
v is the speed of the wave
f is the frequency of the wave
For the sonar signal in this problem,
Substituting into the equation, we find the wavelength:
D.<span>Wave 3 resulted from constructive interference, and Wave 4 resulted from destructive interference.

Use the definition of acceleration:
Acceleration = (change of velocity) divided by (time for the change)
The graph says:
Change of velocity = -6 m/s
Time for the change = 3 sec
So Acceleration = (-6m/s) / (3 s)
That's -6/3 m/s•s
or
-2 m/s^2
