Answer: Flow rate 1670 cm³/s

Explanation:   Cross section  A =  π · (2 cm)²  = 12.56 cm²

                     V = 1000 l   , t = 10 min = 600 s

                       dV / dt = 1000 l / 600 s = 1,67 l/s = 1670 cm³ /s

                     <em> That was not asked,</em>

<em>                    dV / dt = vA  and flow speed v = (dV/dt)/A = 133 cm/s</em>

A pulled tablecloth exerts a frictional force of 0.6 n on a plate with a mass of 0.4 kg. what is the acceleration of the plate?
Ludmilka [50]
The formula for acceleration is a = F/m; Where: F = force; m = mass
Given: F = .6n; m = .4kg; a = ?
a = F/m
  = .6/.4
  = 1.5

Therefore, the acceleration of the plate is 1.5 m/s^2
