Suppose a certain battery has an internal emf of 9.00 V but the potential difference across its terminals is only 80.0 % of that

value. Part A If that battery is connected to a 44.0 μF capacitor, how much energy is stored when the capacitor is fully charged? Express your answer with the appropriate units. UEU E = nothing nothing Request Answer

Answer:

1140.48\times 10^{-6}J

Explanation:

We have given that the battery has an internal emf of 9 volt

So E = 9 volt

Capacitance C=44\mu F=44\times 10^{-6}F

It is given that on the terminal voltage is only 80% of potential difference

So V = 0.8×9 = 7.2 volt

We know that energy stored in the capacitor is given by

E=\frac{1}{2}CV^2=\frac{1}{2}\times 44\times 10^{-6}\times 7.2^2=1140.48\times 10^{-6}J

An student writes a bird that is divining for prey has speed of _ 10m/s what is wrong with the statement.
Anika [276]

Answer:

The description including its issue is summarized throughout the clarification portion below.

Explanation:

  • Speed would be a measurement of size. Which has only significance and therefore no path or guidance. Student says acceleration of -10m/s, therefore this assumption is incorrect because this same negative correlation indicates the path.
  • In reality, this same participant defined the speed (which seems to have two very different motion of an object).
