Part F What are some potential applications of a material that make things invisible?​

Answers

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 wave is caused by vibration

sound waves, water waves, or seismic waves.

Answers

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.

sound waves because sound waves use sound to travel and vibration is also a sound so therefore is sound waves

How can you make a sound louder?

adding more frequency

removing energy

removing frequency

adding more energy

Answers

Answer:

BY adding more energy

Explanation:

Because by adding energy  it will cause the string/sound to vibrate more which can cause more air particles to more and longer making the sound louder.

Adding more energy the answer

What do you have to do to become faster at running?

Answers

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.
