Answer:

1.6 above water

Step-by-step explanation:

Total length of the pipe = length below the water + length above the water

We know the total length of the pipe =3.1  and the length below the water is 1.5 m

3.1 = 1.5 + length above the water

Subtract 1.5 from each side

3.1 -1.5 = 1.5 -1.5 + length above water

1.6 = length above water

11. Suppose a force F varies as the product of two masses, m and M, inversely as
almond37 [142]

Answer:

k = 6.74 * 10^{-5}

Step-by-step explanation:

Given

F\ \alpha\ \frac{m * M}{r^2} --- The variation

F = 675; m = 125; M = 225; r = 0.0530

Required

Determine the constant of proportionality (k)

F\ \alpha\ \frac{m * M}{r^2}

Express as an equation

F = k\frac{m * M}{r^2}

Multiply both sides by r^2

Fr^2 = km * M

Make k the subject

k = \frac{Fr^2}{m * M}

Given that: F = 675; m = 125; M = 225; r = 0.0530

We have:

k = \frac{675* 0.0530^2}{125 * 225}

k = \frac{1.896075}{28125}

k = 0.000067416

This can be represented as:

k = 6.74 * 10^{-5}
