Answer:

A. internal

Explanation:

Engine is the name given to the equipment responsible for turning energy into motion of the vehicle in which it is installed. In the case of cars and other vehicles, the engine is called “internal combustion” because it transforms the burning of fuels in its interior in motion.

Regardless of engine type, everyone needs the same elements: air, fuel, and an explosion trigger. In Otto engines, this trigger is provided by the spark plug, which unleashes a spark inside the cylinder and generates the explosion. In diesel engines, such an explosion is generated by the compression of gases within the cylinder and the elevated temperature.

A. Internal. Most cars use that type of set up because it's more efficient, you can find more about it on this website, https://auto.howstuffworks.com/did-cars-ever-have-external-combustion-engines.htm

There are several different models that represent compounds. One type of model is shown.
Mrac [35]

Answer: Option (a) is the correct answer.

Explanation:

A formula that represents how atoms are linked or joined together is known as a structural formula.

For example, the model given in the image (in question) represents arrangement of all the atoms. Therefore, it is a structural formula.

Whereas a chemical formula represents a compound along with ratio of compounds.

A space filling model and a ball-stick model is a three dimensional model. In space filling model atoms are represented by spheres whereas in ball stick model atoms are represented by ball and bonds are represented by stick.

Recall some things you already know about projectile motion. Does a force in the vertical direction affect the horizontal compon
azamat

Answer:

vertical force cannot change the velocity on the x-axis.   t =x/v₀ₓ

Explanation:

The force is a vector magnitude, so the forces on the x-axis affect the acceleration on this axis. Consequently a vertical force cannot change the velocity on the x-axis.

     F_{y} = m g

    Fₓ = 0

The horizontal velocity in projectile motion is constant, if we neglect the air resistance, so it can be used to find the time of a horizontal displacement

       x = v₀ₓ t

       t =x/v₀ₓ

The only magnitude that is the same for both movements is the time that is a scalar

How does emission spectra occur?
Lerok [7]

The frequencies of light that an atom can emit are dependent on states the electrons can be in. When excited, an electron moves to a higher energy level or orbital. When the electron falls back to its ground level the light is emitted.

hope this helped:)

Calculate the average orbital speed of Ceres in
marin [14]
] Ceres is composed of rock and ice and is estimated to comprise approximately one third of the mass of the entire asteroid belt. Ceres is the only object in the asteroid belt known to be rounded by its own gravity (though detailed analysis was required to exclude 4 Vesta). From Earth, the apparent magnitude of Ceres ranges from 6.7 to 9.3, peaking once every 15 to 16 months,[21]hence even at its brightest it is too dim to be seen with the naked eye except under extremely dark skies.
