Answer:
the correct answer is C, 281 lb
Explanation:
This is an exercise in fluid mechanics specifically on Pascal's principle, which states that the pressure in a fluid is equal to all points that are at the same depth
P = 
= 
If we use the subscript 1 for the piston diameter mentor (d = 1.00vm) which is r = 0.05 cm, the force is F1 = 45 lb
F₂ = \frac{F_{1} }{A_{1} } F₁
in area of a circules
A = π r²
we substitute
F₂ = 
let's calculate
F2 = 2.50² / 1.00² 45
F2 =281 lb
therefore the correct answer is C
The wave characteristic that is the same for both waves is wavelength.
- Two waves with the same frequency will also have the same wavelength, amplitude, speed, and period. When two waves are travelling at the same frequency, it denotes that their duration and amplitude are also the same.
- When two waves of the same frequency and amplitude interfere constructively, their peaks and troughs align as shown in diagram A above. As a result, the original waves' amplitude is doubled, resulting in a sound wave that is twice as loud.
Thus, Equal frequencies are shared by two waves moving through the same region in the same direction.

Well, first of all, let's not make something complicated ... for which we're missing an important component anyway ... out of something simple. There's more to "velocity" than 'meters per second'. So let's just call that what it is: " Speed ".
Here's what you've told us:
-- Something is moving along a ruler or meter stick.
-- At every instant from time=0 to time=5, its speed was constant at 4 m/s.
-- At time=0, it was located at 6m .
We can calculate:
-- Moving steadily at 4 m/s for 5 seconds, it moved (4 x 5) = 20 meters.
-- If it was located at 6m when time=0, then at time=6, it had advanced
to (6 + 20) = 26 meters.
