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.

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.
what wave is caused by vibration
sound waves, water waves, or seismic waves.
Answer:
In the first part of Lesson 1, it was mentioned that sound is a mechanical wave that is created by a vibrating object. The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium.

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.

My actual question: How does the universe work and what is beyond it. It doesn't have to be correct, it just needs to be a theory (at least)
The universe is everything, so it isn't expanding into anything. It's just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there's no center they're expanding from and no outer edge to expand into anything else.
Forces that cause a change in the motion of an object.
Wobbly Forces
Net Forces
Unbalanced Forces
Balanced Forces
