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}

Answer: 60 L

Step-by-step explanation:

Given

The measurement of a rectangular vessel is 40\ cm\times 30\ cm\times 50\ cm

If we multiply the given terms then it will give the volume of the rectangular vessel in cm^3.

So, the volume of the rectangular vessel is

\Rightarrow V=60,000\ cm^3

Also, we know 1000\ cm^3=1\ L i.e. to convert  cm^3 to L, divide the result by 1000.

\Rightarrow V=60,000\ cm^3=60\ L
