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 are magnetic field lines helpful when studying magnets?
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:
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.

What do you do if a dog is chasing you?
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.

Part F What are some potential applications of a material that make things invisible?
Answer:
part a = Light takes slightly more time to move around an invisible object than to move in a straight line. People can see this difference even if they can’t see the object.
part b = It works under hazy conditions, such as in fog, in a cloud, or when viewed through frosted glass.
part c = It’s hard to see objects in a fog or haze because light bounces off tiny particles suspended in the air.
part d = In fog, the light moves like a pinball and bounces off tiny particles suspended in the air. It takes longer for light to pass around an object.
part e = Scientists want the invisibility coating to guide light around an object. They don’t want the coating to emit or reflect light.
part f = Here are a few possible answers:
The material won’t heat up because it doesn’t absorb much light.
The material can be used for privacy.
The material can be used to hide important machines in the event of war.

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
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 have to do to become faster at running?
Answer: Get stronger. Strength is critical to running fast because the more force you can exert against the ground the faster you can run.
Apply your new strength. Being strong is important for sprinting, but the ability to apply it is even more important. Sprinters move in a horizontal direction.
Take longer steps more quickly. Today, the concept of exerting more force against the ground is very popular for improving speed. ...
Run fast to get fast. Of all the strategies described in this article, this is the most important and often the most overlooked.
