How much charge flows from a 6.0 v battery when it is connected across a completely discharged 15.7 μf capacitor?
Lilit [14]
The equation Q=CV (Charge = product of Capacitance and potential difference) tells us that the maximum charge that can be stored on a capacitor is equal to the product of it's capacitance and the potential difference across it. In this case the potential difference across the capacitor will be 6.0V (assuming circuit resistance is negligable) and it has a capacitance of 15.7<span>μf or </span> 15.7x10^-6f, therefore charge equals (15.7x10^-6)x6=9.42x10^-5C (Coulombs).

Motor oil, with a viscosity of 0.25 N ∙ s/m2, is flowing through a tube that has a radius of 3.0 mm and is 1.0 m long. The drop
Alex73 [517]

Answer:

The average speed of the oil is 1 m/s.

Explanation:

Given that,

Viscosity \eta= 0.25 N-s/m^2

Radius r = 3.0 mm

Length = 1.0 m

Pressure = 200 kPa

We need to calculate the average speed of the oil

Using formula of pressure

\Delta P=\dfrac{8\pi\eta\rho v}{A}

v=\dfrac{A\times\Delta P}{8\pi\eta\rho}

Where, A = area

\rho = density of oil

\eta = viscosity

Put the value into the formula

v=\dfrac{\pi\times(3.0\times10^{-3})^2\times200\times10^{3}}{8\pi\times0.25\times0.9}

v=1\ m/s

Hence, The average speed of the oil is 1 m/s.
