A 800 kg car zooms away from a red light with an acceleration of 7.6 m/s2. What is the
aev [14]

Answer:

6080 N

Explanation:

From the question given above, the following data were obtained:

Mass (m) of car = 800 Kg

Acceleration (a) of car = 7.6 m/s²

Force (F) =?

The force experienced by the car can be obtained as illustrated below:

Force (F) = mass (m) × acceleration (a)

F = m × a

F = 800 × 7.6

F = 6080 N

Thus, the experience a force of 6080 N

Using Newton’s laws of motion, describe the motion of a roller coaster and analyze the forces acting on the roller coaster at di
Illusion [34]

We can apply Newton's third law of motion in roller coaster.

Explanation:

  • If we are planning to make a roller coaster with elevations and turn then we need to apply newton’s law of motions, kinetic energy and potential energy.
  • Newton’s third law of motion says that “ for every action, there is an equal and opposite reaction”. Newton’s third law of motion applies between the tract and ride vehicles.
  • If we neglect the air resistance and friction, Roller coaster car will always experience two types of forces which are gravitational force and normal force. The normal force is acting perpendicular to the track and gravitational for is also acting downwards.
  • Whenever the tracts get moving the gravitational force is attracting roller coaster to downward. So this will get accelerates. In the majority of the roller coasters, the hill will decrease with height as the train moves along the tract.

Identify which of these molecules has the highest boiling point and give the reasoning why in terms of intermolecular force. CHC
PolarNik [594]

Answer:

CH3COOH

Explanation:

CH3COOH has the highest boiling point because it participates in the strongest intermolecular interactions. The -OH group can participate in hydrogen bonding with other -OH groups. Hydrogen bonds are very strong because they are the result of large partial positive charge on the hydrogen and large partial negative charge on the oxygen. When surrounded by other -OH groups, the partial positive charge on the hydrogen can form temporary bonds with the partial negative charge of an oxygen on another molecule. The stronger the intermolecular interactions, the more difficult they are to overcome, thus increasing the boiling point.

The strongest IMF the other molecules participate in are dipole-dipole. These interactions are not as strong as hydrogen bonding.

1) In the boxes below, draw the model given in the simulation and draw a model of the molecules in an object when the object
sladkih [1.3K]

The molecules of the cold element are going to be closer together and still than the molecules of the hot element because the heat energy causes the molecules to be stimulated and to move.

<h3>How do molecules act at different temperatures?
</h3>

In the image you can see the behavior of the molecules when they are in different environments. On the right you see the cold molecules and on the left the hot molecules that are characterized by the following characteristics:

Cold molecules:

  • Molecules together.
  • Molecules with little movement.

Hot molecules:

  • Separate molecules.
  • Molecules with active movement.

A simple example to understand this behavior of molecules is water because:

  • When water is frozen its molecules are almost static and close together.
  • When the water is liquid and it is heated, the molecules move and that is why the water has bubbles, its molecules are separated.

What three things act on decaying organisms to help form fossil fuels
dimulka [17.4K]
<span>The fossil fuels form from the buried remains of ancient organisms, </span>formed from the remains of dead plants and animals.
<span> These plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years. So, three things that act on decaying organisms to help form fossil fuels are:
-pressure
-heat
-physical and chemical changes
People  use fossil fuels products for transportation and heating, many power plants burn coal for heat to turn turbines that generate electrical energy. ...</span>
