Answer:
<em>The correct difference is 3.44 ft</em>
Explanation:
The correct difference is given as
D=R_A-R_B
D=9.09-5.65
D=3.44 ft
Let's find the relationship
- So if frequency increases Energy of the wave increases and wavelength decreases and vice-versa
Weight = (mass) x (acceleration of gravity) .
On Earth, acceleration of gravity is 9.8 m/s² (rounded) .
650 N = (mass) x (9.8 m/s²)
Divide each side by (9.8 m/s²): 650 N / 9.8 m/s² = mass
Mass = 66.3 kilograms (rounded)
To get x on its own, you times the 3 over to the other side so the 3 cancels out on the LHS.
~ x greater than or equal to -18

The answer would be to research the need. This should have been done before the project began.
