Earth has a definite orbit within the solar system whose the orbit is mainly a result of the mass of the Sun.

An orbit is defined as the regular, repeating path that one object in space takes around another while an object in an orbit is called a satellite which may be natural, such as the Earth or the Moon. According to the height of satellites from the earth, these orbit are classified as

Most of the weather and some communications satellites will tend to have a high Earth orbit which is farthest away from the surface. The main difference between orbit and orbitals is that the former is defined as a fixed path of electron revolutions, whereas the latter is defined as an uncertain region with a high probability of finding an electron.

Therefore, the Earth has a definite orbit within the solar system whose the orbit is mainly a result of the mass of the Sun.

Answer:

[tex] \huge\boxed {\sf Velocity}[/tex]

Explanation:

The unit of measurement is m/s hence it can not inertia or force because the unit of intertia and force are kg m² & kg⋅m/s² respectively, hence Option C and Option D can not be the right answer.

To understand the final answer one must know the difference between velocity and speed.

Velocity is a vector quantity which is direction specific. It's the displacement per unit time, the displacement is an vector quantity.

[tex] \sf \: Velocity = \frac{Displacement }{Time} [/tex]

Velocity can be positive negative or zero!

Speed is a scalar quantity which tells the distance covered in unit time. since it's a scalar it have magnitude only, not direction.

[tex] \sf \: Speed = \frac{Distance }{Time} [/tex]

Speed is always either zero or positive.

In the question it tells the baseball is flying through the air at 40 m/s east,

if it was only 40m/s with no direction then it would be speed. but the east is indicating the direction and velocity includes the direction hence the given measurement represents Velocity.

A star will become a white dwarf when its nuclear fuel is finished because of no more emission of heat and light.

When the end of the nuclear burning stage of a star comes, such a star expels most of its outer material creating a planetary nebula until only the hot core remains. When this core settles down, it will become a young white dwarf.

So we can conclude that a star will become a white dwarf when its nuclear fuel is finished because of no more emission of heat and light.

Let's see

m is mass and v is velocity

You almost certainly meant to say the particle's position is a function of time t, not some other variable x (or vice versa) so that

s(t) = 5t sin(2t)

Differentiate s(t) to get the instantaneous velocity of the particle at time t. By the product rule,

s'(t) = 5 sin(2t) + 10t cos(2t)

Evaluate the derivative at t = 0 :

s'(0) = 0

The instantaneous velocity at t = 0 is 0 m/s.

To find the instantaneous velocity at t = 0, we need to take the derivative of the position function s(t) with respect to time (t). The derivative of s(t) gives us the velocity function v(t), which represents the particle's velocity at any given time t.

Given the position function s(t) = 5t * sin(2t), we find the velocity function v(t) by taking the derivative:

v(t) = d/dt (5t * sin(2t)).

To find the velocity at t = 0, we substitute t = 0 into the velocity function:

v(0) = 5 * 0 * sin(2 * 0) = 0.

Therefore, the instantaneous velocity of the particle at t = 0 is 0 m/s. This means that at t = 0, the particle is momentarily at rest, and its velocity is neither increasing nor decreasing at that specific moment.

The fact that large elliptical galaxies are more common in central galaxy clusters suggests that collisions play a role in the formation of these galaxies.

Galaxy formation is a physical phenomenon where molecular clouds of dust concentrate and thus first generate stars.

Galaxy formation is a process that can be associated with collisions, at least for the formation of elliptical galaxies.

Collisions are a relatively frequent process in clusters (groups) of galaxies that are formed by crashes with other galaxies.
