(a) A 1.00-μF capacitor is connected to a 15.0-V battery. How much energy is stored in the capacitor? ________ μJ (b) Had the ca

gulaghasi [49]

Answer:

(a) $E_{ c} = 112.5 \mu J$

(b) $E'_{ c} = 18 \mu J$

Solution:

According to the question:

Capacitance, C = $1.00\mu F = 1.00\times 10^{- 6} F$

Voltage of the battery, $V_{b} = 15.0 V$

(a)The Energy stored in the Capacitor is given by:

$E_{c} = \frac{1}{2}CV_{b}^{2}$

$E_{c} = \frac{1}{2}\times 1.00\times 10^{- 6}\times 15.0^{2}$

$E_{ c} = 112.5 \mu J$

(b) When the voltage of the battery is 6.00 V, the the energy stored in the capacitor is given by:

$E'_{c} = \frac{1}{2}CV'_{b}^{2}$

$E'_{c} = \frac{1}{2}\times 1.00\times 10^{- 6}\times 6.0^{2}$

$E'_{ c} = 18 \mu J$

What parts of an atom can change during a nuclear reaction that cannot change during a chemical reaction? Question 15 options: A

viva [34]

Neutrons and protons cannot be removed from nucleus from chemical reactions because they are strongly held together but nuclear reactions are strong enough to separate them. Hence option A is correct.
