A cube-shaped water tank having 6 ft side lengths is being filled with water. The bottom is solid metal but the sides of the tan
Mekhanik [1.2K]

Answer:

0.033 ft

Step-by-step explanation:

Let g = 32.2 ft/s2 and h be the maximum height that water can be filled before the sides shatter.

Pressure is distributed from 0 to maximum at the bottom like the following equation:

P = \rho gh

So the force generated by water pressure on the side of the tank is

F = PA = \rho ghs/2

where s = 6ft is the side length of the tank. This force cannot be larger than 200lb

\rho ghs/2 \leq 200

62.4*32.2*h*6/2 \leq 200

h \leq 0.033 ft

larisa [96]

Answer:

20 feet

Step-by-step explanation:

\frac{80 feet}{40 seconds}  = \frac{x feet}{10 seconds}

Simplify \frac{80}{40}

\frac{80}{40} = \frac{2}{1}

Every 1 second, a person will walk 2 feet.

\frac{x}{10} = \frac{20}{10}

X = 20 feet
