Answer:

Explanation:

Capacitance, C = 1.6 F

(a) V = 12 V

Energy stored in a capacitor,

U = 0.5 C V²

U = 0.5 x 1.6 x 12 x 12 = 115.2 J

(b) V = 24 V

Energy stored in a capacitor,

U = 0.5 C V²

U = 0.5 x 1.6 x 24 x 24 = 460.8 J

Answer:

Energy stored at 12 volt will be 115.2 J and energy stored at 24 volt will be 460.8 volt

Explanation:

We have given capacitance of capacitor C = 1.6 F

Normal voltage V = 12 volt

And system uses 2 volt to charge the system

We know that energy stored in the capacitor is equal to E=\frac{1}{2}CV^2

So energy stored at 12 volt will be equal to E=\frac{1}{2}\times 1.6\times 12^2=115.2j

And energy stored at 24 volt will be equal to E=\frac{1}{2}\times 1.6\times 24^2=460.8j

So energy stored at 12 volt will be 115.2 j and energy stored at 24 volt will be 460.8 j

How is magnetism important to our evolution?
sweet [91]
If it helps Mark Brainliest.. :)

natural magnetism of the Earth derives from its iron core. This not only provides a useful direction finder for compasses, but actually protects life on Earth by deflecting charged particles in space. The "magnetosphere" is a large region that surrounds the Earth as it moves in its orbit around the Sun. It consists of charged ions that are prevented from directly striking the surface, where they could injure living organisms and harm the environment.When solar eruptions on the Sun increase the flow of charged particles, industries such as power transmission and communication can be still be affected despite the magnetic field

When I wave a charged golf tube at the front of the classroom with a frequency of two oscillations per second, I produce an elec
borishaifa [10]

To solve the exercise it is necessary to take into account the concepts of wavelength as a function of speed.

From the definition we know that the wavelength is described under the equation,

\lambda = \frac{c}{f}

Where,

c = Speed of light (vacuum)

f = frequency

Our values are,

f = 2Hz

c = 3*10^8km/s

Replacing we have,

\lambda = \frac{c}{f}

\lambda = \frac{3*10^8km/s}{2Hz}

\lambda = 1.5*10^8m

<em>Therefore the wavelength of this wave is 1.5*10^{8}m</em>

Suppose you illuminate two thin slits by monochromatic coherent light in air and find that they produce their first interference
strojnjashka [21]

Answer:

1.7323

Explanation:

To develop this problem, it is necessary to apply the concepts related to refractive indices and Snell's law.

From the data given we have to:

n_{air}=1

\theta_{liquid} = 19.38\°

\theta_{air}35.09\°

Where n means the index of refraction.

We need to calculate the index of refraction of the liquid, then applying Snell's law we have:

n_1sin\theta_1 = n_2sin\theta_2

n_{air}sin\theta_{air} = n_{liquid}sin\theta_{liquid}

n_{liquid} = \frac{n_{air}sin\theta_{air}}{sin\theta_{liquid}}

Replacing the values we have:

n_{liquid}=\frac{(1)sin(35.09)}{sin(19.38)}

n_liquid = 1.7323

Therefore the refractive index for the liquid is 1.7323
