Answer 1

What is common between transverse waves and longitudinal waves?

Both include an amplitude, crest, and rarefactions
Both move faster at higher temperatures
Both move slower through densely packed molecules
Both include a wavelength from compression to compression

Answer 2

The lens in the eyepiece of a reflecting telescope breaks. How will this most affect the function of the telescope?

Magnified images will appear upside down.
Magnified images will not be created.
Light from distant objects will not be captured.
Light rays will not be sent to the eyepiece.

Answer 7

Which best describes a benefit of using lasers instead of traditional cutting machines?

Laser machinery does not require energy.
Laser machinery is safer because its light is weak.
Lasers save time by cutting through more layers of fabric.
Lasers result in fewer injuries because they quickly become blunt.

Answer 8

C is the only one that makes sense

Answer 9

How does a convex mirror form an image?

It bends the light toward a focal point.
It bends the light away from a focal point.
It bounces the light toward a focal point.
It bounces the light away from a focal point.

Answer 10

Answer 13

How does a convex mirror form an image?

It bends the light toward a focal point.

Answer 14

Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.-Physics classroom

Answer 21

Which factors affect the strength of the electric force between two objects?

the mass of the objects and the distance between the objects
the amount of charge on the objects and the type of charge on the objects
the distance between the objects and the amount of charge on the objects
the mass of the objects and the amount of charge on the objects

Answer 22

distance traveled / time

Answer 23

i alright got that one sadly

Answer 24

the distance between the objects and the amount of charge on the objects

Answer 25

A negatively charged rod is placed near two neutral metal spheres, as shown below.



Which statements describe the charging method shown? Check all that apply.

The spheres develop opposite charges.
The spheres develop the same charge.
Electrons move from the rod to Sphere A.
Electrons move from Sphere A to Sphere B.
The spheres are charged through conduction.
The spheres are charged through friction.
The spheres are charged through induction.

Answer 26

-->The spheres develop opposite charges.
-->Electrons move from Sphere A to Sphere B
-->The spheres are charged through induction.

Answer 27

How does increasing the distance between charged objects affect the electric force between them?

The electric force increases because the distance has an indirect relationship to the force.
The electric force increases because the distance has a direct relationship to the force.
The electric force decreases because the distance has an indirect relationship to the force.
The electric force decreases because the distance has a direct relationship to the force.

Answer 28

A small, positively charged ball is moved close to a large, positively charged ball. Which describes how the small ball likely responds when it is released?

It will move toward the large ball because like charges repel.
It will move toward the large ball because like charges attract.
It will move away from the large ball because like charges repel.
It will move away from the large ball because like charges attract.

Answer 29

will move toward the large ball because like charges repel.

Answer 30

How does increasing the distance between charged objects affect the electric force between them?

The electric force increases because the distance has an indirect relationship to the force.
The electric force increases because the distance has a direct relationship to the force.
The electric force decreases because the distance has an indirect relationship to the force.
The electric force decreases because the distance has a direct relationship to the force.

Answer 31

The electric force decreases because the distance has an indirect relationship to the force.
