Hi there!

We can use the equation for the charge of a charging capacitor:
[tex]q(t) = C\epsilon( 1 - e^{-\frac{t}{RC}})[/tex]

Using Capacitor equations:
[tex]C = \frac{Q}{V}}\\\\Q = CV[/tex]

Therefore, Cε equals the steady-state charge of the capacitor (the function approaches this value as t ⇒ ∞.

We can plug in the givens and solve.
[tex]\epsilon = 5 V\\\\C = 100\mu F = 0.0001 F[/tex]

[tex]Q = C \epsilon = (0.0001)(5) = \boxed{0.0005 C}[/tex]

The charge on the capacitor when the circuit has reached a steady-state is 0.0005C.

The capacitance of a conductor is defined as the ratio of the quantity of electric charge stored on it to the difference in electric potential.

Given that the resistance of the resistor is 20 kω, while the capacitance of the capacitor is 100 μf, and the voltage of the battery is 5V.

Now, the charge on the capacitor when the circuit has reached a steady-state can be written as,

[tex]Q=CV\\\\Q = 100\mu F \times 5V\\\\Q = \dfrac{100}{1,000,000}F \times 5V\\\\Q = 0.0005C[/tex]

Hence, the charge on the capacitor when the circuit has reached a steady state is 0.0005C.

Answer:

The age of the bedrock increases the further you get away from the mid atlantic ridge because it is at the ridge that the new bedrock is formed. At the Ridge, the diverging plates cause magma to rise up and harden, forming new bedrock. As this happens, the older bedrock is pushed outwards, further and further away from the Ridge.

If an electric circuit has zero Ampere (0A) of current running through it, then the voltage must be zero.

At constant temperature, Ohm's law says that the current flowing through an electric circuit is directly proportional to the voltage

Also, the current flowing through an electric circuit is inversely proportional to the resistance in the electric circuit.

This means that the magnitude of voltage (potential difference) is significantly reliant on the value of current flowing through an electric circuit.

This formula expresses Ohm's law mathematically.

V=IR

Where:

V is the voltage is measured in volts.

I denote the current in amperes.

R denotes the resistance in ohms.

Finally, if an electric circuit has zero ampere (0A) of current flowing through it, the voltage must also be zero.

Explanation:

1. Solar wind is the solar wind is a stream of radiation particles that are released from the last layer of the Sun and the Earth’s magnetic field acts to deflect solar winds, where as the Van Allen belt refers to the area of charged particles in the magnetosphere. The aurora is produced by the collisions between charged particles from solar winds and gases present in the last layer of the atmosphere. 

2. When the solar wind encounters Earth, it is deflected by our planet's magnetic shield, causing most of the solar wind's energetic particles to flow around us. 

3. The Van Allen radiation belt is a zone of energetic charged particles, which can originate from the solar wind. The particles are then captured by and held around a planet by that planet's magnetic field.

4. An aurora is that natural light displayed in the Earth's sky, predominantly seen in high-latitude regions. Auroras are the result of disturbances in the magnetosphere caused by the solar wind.

The speed of the wave will be v= 448.07 m/s

The speed of the wave is defined as the distance traveled by the wave with respect to the time.

The frequency is defined as the number of cycles per seconds it is calculated in hertz

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.

Now frequency = 173 hertz

wavelength = 2.59 m

The velocity will be given by the formula:

A protostar is the earliest stage of a star's life. A star is born when the gas and dust from a nebula become so hot that nuclear fusion starts.

The origin of star is called nebula. The earliest stage of a star’s life before it begins to undergo fusion is known as a protostar.

Every star begins from nebula. A nebula is a huge gas and dust cloud. Some of the gas and dust in a nebula can be drawn together by gravity. The cloud's contraction is then described as a protostar. The first stage of a star's life is called a protostar.

As the gas and dust from a nebula heat up to a point where nuclear fusion begins, a star is created. A star is referred to as a main sequence star once it has "switched on". A main sequence star turns into a red giant or a red super giant when its hydrogen fuel runs exhausted.

An exploding red super massive star is possible. It is referred to be a supernova. After the star explodes, some of the ingredients from the star are left behind. Hence, the earlier stage of a star before fusion starts is called a protostar.
