Which increases the amount of thermal energy on Earth according to scientists?

An increase in greenhouse gases has trapped heat.

More heat from Earth’s core is being conducted to the surface.

There is more convection occurring on Earth.

The sun has grown brighter.

Answers

Answer:

More heat from Earth’s core is being conducted to the surface.

Explanation:

According to scientists more heat from earth's core being conducted to the surface increases the amount of thermal energy.

What is thermal energy?

Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.

Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.

These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.

how can i help when we don’t see the experiment?

I do not know the exact question. But I can explain what weathering and erosion is to possibly help you.
Weathering- The process of wearing or being worn by long exposure to the atmosphere. (Usually rain and wind).
Erosion-The process of eroding or being eroded by wind, water, or other natural agents. (Such as acid rain over time slowly cutting into a rock and breaking it down into minerals).

Answer:

1. An object in motion will stay in motion: A car, and its breaks.

2. Force = mass x acceleration: Kicking a ball.

3. Equal or Opposite reaction: Tugging on your dogs leash as hes trying to run off.

Explanation:

One force pushes a stationary object east at 10 newtons, and another force pushes west at 5 newtons. Which way will the object move?
A.
east
B.
west
C.
north or south
D.
it will not move

Answers

Answer: A. East

Explanation: It will be going in the east direction at 5 newtons.

When one force pushes a stationary object east at 10 newtons, and another force pushes west at 5 newtons, then the object will move east,

Therefore the correct answer is option A.

What is Newton's second law?

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

F = ma

A stationary item will move east when one force pushes it east at 10 newtons and another force pushes it west at 5 newtons,

The net force on the stationary object = 10 Netwon toward east - 5 Newton toward the west

The net force on the stationary object would be 5 Newton toward the east direction resulting in the eastward motion.

Thus, the correct answer is option A.

What do you do if a dog is chasing you?

Answers

Answer:

run.

Explanation:

Answer:

The first thing to do if a dog charges you is to remain calm.

If the dog is trying to bite you, try and block the attack with something you have on you.

If the dog is large enough to push you over, tuck yourself up into a ball and clasp your hands around the back of your head

If the dog bites and holds, je.rking away can damage you more than if you stay in position. Remember to stay calm.

If you have the chance to run, try to get somewhere out of reach of the dog.

If you are near playground equipment, climp out of reach of the dog.

how are magnetic field lines helpful when studying magnets?

Answers

Answer:

If the magnetic field lines are closer to each other, the magnetic field strength is generally stronger. For example, in a bar magnet, the magnetic field lines are always densest when they are close to either pole. This signifies that the magnetic field gets stronger as we get closer to its source.

Explanation:

Earth's magnetic field is thought to play an important role in making the planet habitable. Not only does a magnetic field set the direction of our compass needles, it also acts as a shield of sorts, deflecting away solar wind that might otherwise eat away at the atmosphere.
