Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ice. Sun is a nearly perfect ball of hot plasma, heated to incandescence in its center by nuclear fusion reactions. Comets can be compared to the sun on the basis of size, composition, and position in the solar system.

<h3>What is the sun?</h3>

The Sun is the central star of our Solar System. It's a nearly perfect ball of hot plasma, heated to incandescence in its center by nuclear fusion reactions.

Sun emits energy mostly as visible light, ultraviolet light, and infrared radiation. It is the most vital source of energy for life on Earth.

<h3>What are comets?</h3>

A comet is a tiny entity circling the Sun that contains a significant amount of volatile ices, which includes entrained dust particles.

The comet forms two tails, one of ionized molecules and radicals and the other of dust, as dust and gas in the coma flow freely into space.

Comets are frozen remnants of the solar system's origin, made of dust, rock, and ice.

They range in size from a few miles to tens of miles across, but as they get closer to the Sun, they heat up and spew gases and dust into a flaming head the size of a jet.

Hence comets can be compared to the sun on the basis of size, composition, and position in the solar system.

What causes an electrical current in a wire? Question 1 options: Electric fields cause atoms to move in a wire Electrons build u
Mademuasel [1]

The cause of electric current in a wire is that there is electron flow due to electrical attraction and repulsion.

What is Electric current?

The rate of flow of electric charge through a point is known as electric current. The electric current is nothing but the flow of electrons in general.

Consider a space, when electrons of charge (e) is flowing through the space in a given time interval t. Then,

I = e/t

here,

I is the electric current.

Moreover, there is a flow of electrons in a wire due to a potential difference existing at the circuit. Due to that, electrons always flow from high electric potential to low electric potential.

Thus, we can conclude that the cause of electric current in a wire is that there is electron flow due to electrical attraction and repulsion.

Anaya Goodloe decides to spike the football after a big touchdown (on Earth) and it
Llana [10]

Answer:

The football leaves with the velocity, u = 15.68 m/s

Explanation:

Given data,

The football bounces back up off the ground and is airborne for, t = 3.2 s

Let the football bounces back up off the ground in the vertical direction

The formula for time of flight is given by,

                              t = 2u /g

∴                             u = gt / 2

Substituting the values,

                               u = 9.8 x 3.2 / 2

                                u = 15.68 m/s

Hence, the football leaves with the velocity, u = 15.68 m/s
