Please please answer this! explain the kinetic molecular theory ( i don't understand how they explain it in my lesson so if someone could simpfly it for me) worth 30 points

Answers

Answer 1

Answer:

Explanation:

Basically, Kinetic Molecular Theory says that gas particles are in constant motion and that they show perfectly elastic collisions.

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision.

So the kinetic molecular theory says that gas particles stay moving constantly and don't lose energy when they run into each other.

Hope this helps!

Power is the rate at which work is done. James Watt is a famous engineer and inventor who developed the steam engine.

Who is James Watt?

He improved the efficiency of the engine by adding a separate condenser, which reduced the amount of fuel needed. In his honor, the watt was named after him as the unit of power.

A skydiver dives from an airplane. Air resistance is measured each second following the skydiver’s jump. Which statement BEST identifies the skydiver’s speed at each second?
PLS HELP QUICK

Answers

Answer: (B) 4 Seconds

Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)

Answer : B. The sjydriver has the fastest speed at 4second.

What is air resistances ?

--Air resistance is a type of friction force.

-- Air resistance, there are not two solid surfaces in contact.

-- Air resistance is the frictional force acting on an object and the air around them.

--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.

Concept Used

-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.

-- A person’s weight force will always stay the same.

-- The weight force of the person will equal their air resistance.

-- This would make the skydiver travel at constant speed.

--To travel at constant speed forces have to be equal to zero.

--This constant speed is called terminal velocity

If a roller coaster cart needs more Kinetic Energy to reach the top of the track, what are two ways to increase the amount of Kinetic Energy the cart has? Provide evidence to support your answer.

Answers

Answer:

Increase the mass or velocity.

Explanation:

The formula of Kinetic Energy is Ek=1/2*m*v^2. So both increase the mass or velocity can increase the Ek.

Kinetic energy of an object depends on its mass and velocity. Therefore, the roller caster can gain more kinetic energy by increasing its velocity. Increase in mass by loading the cart can also helps to increase its kinetic energy.

What is kinetic energy ?

Kinetic energy of an object is generated by virtue of its motion. Whereas, the when the object is at rest, the energy is stored in the form of potential energy.

The kinetic energy of a body is depends on its mass and velocity as per the relation written below:

KE = 1/2 Mv²

Hence, an increase in velocity increases the kinetic energy by 4 times. Similarly an increase in mass also increases the kinetic energy.

Therefore, by increasing its speed and loading more mass, the roller coaster can gain more kinetic energy. Moreover, the way can be more smoothened to avoid the chance of friction.

How do scientists use hotspot volcanism to tell the direction and speed
of a plate?

Answers

Since many hotspots are stationary in the mantle, geologists can use some hotspot chains to tell the direction and the speed a plate is moving. Although most hot spots occur far from plate boundaries, they offer a way to measure plate movement. This is because a hot spot generally stays in one place while the tectonic plate above it. At a hot spot, the heat from the plume partly melts some of the rock in the tectonic plate above it.

A region of the Upper crust where hot plumes can emerge and erupt as volcanoes on the crust above is referred to as the hotspot volcanism.

What is hotspot volcanism?

Hotspots are areas of volcanic activity that are assumed to be fueled by an earth's mantle that is abnormally hot compared to the surrounding mantle. Hawaii, Iceland, and Yellowstone are a few examples. Hotspots may form a chain of volcanoes when the plates move above them because their position just on Earth's surface is autonomous of tectonic plate boundaries.

Geologists will need some hotspot chains to determine the direction and pace at which a plate is moving because many hotspots in the mantle are immobile. The majority of hot spots are located far from continental plates, yet they nonetheless provide a tool to gauge plate mobility. This is due to the fact that a hot point typically doesn't move, unlike the plate boundary above it. The heat from the plume causes some of the rock inside the plate boundary above a hot point to partially melt.

Countries around the world are trying to slow down or reverse the effects of climate change. Based on what you know about the greenhouse effect, which of the following actions would be likely to slow the rise in Earth's average temperature?

Answers

Answer:

Greenhouse gases would warm the earth up causing global warming

Explanation:

To solve this we must be knowing each and every concept related to greenhouse effect. Therefore, greenhouse effect would be likely to slow the rise in Earth's average temperature.

What is greenhouse effect?

The Earth's surface is heated by the greenhouse effect all the way up to the troposphere. Higher concentrations of methane, carbon dioxide, and other gases cause it to occur.

The energy from the sun's heat is reflected back into space as infrared radiation when the Earth's surface cools. The concentrated gases inside the greenhouse effect absorb energy, raising the earth's temperature as a result. Thus, there is a link between the global warming and the greenhouse effect. Greenhouse effect would be likely to slow the rise in Earth's average temperature.

Therefore, greenhouse effect would be likely to slow the rise in Earth's average temperature.
