Answer 2

Something that can change or vary during an investigation

Question 3

What is sound?

Answer 3

Sound is a wave phenomenon produced by vibrating materials

Question 4

What do the vibrations cause?

Answer 4

They cause your ears to vibrate

Question 5

What does the variable length do?

Answer 5

Affects the pitch of the sound

Question 6

What does the variable tension do?

Answer 6

Affect the pitch of a sound

Question 7

What is f the variable for?

Frequency or pitch of the sound in cycles per second.

Question 8

What does the frequency of the sound in cycles per second look like?

1/s

Question 9

N

Question 11

What does the variable L stand for?

Answer 11

Length of a string

Question 12

What is the length of a string measured in?

Answer 12

m

Question 13

What does m stand for?

Answer 13

Mass of the string

Question 14

What is the mass measured in?

Answer 14

kg

Question 15

What does the pitch of a sound correspond to?

Answer 15

The frequency of vibration of the object producing sound

Question 16

What happens when the pitch is high?

Answer 16

The frequency is high

Question 17

If you decrease the length of the vibrating spring, what happens?

Answer 17

It will increase its vibration frequency

Question 18

What happens when you increase the tension in the string?

Answer 18

It will increase the frequency of vibration.

Question 19

What can happen with a tensioned string?

Answer 19

It can produce vibrations

Question 20

What happens when a string is pulled back and released?

Answer 20

The tension in the string accelerates the spring back towards its equilibrium

Question 21

How is the speed which a wave pulse travels along a string determined?

Answer 21

It is determined by the tension in the string and the string’s mass per unit length.

Question 22

What is the tension?

Answer 22

The tension is the force that the rest of the string when a part of the string is pulled to the side away from equilibrium position, the restoring force on that part is equal to the sum of the two components of the tension that are perpendicular to the undisturbed string.

Question 23

What happens with the larger the tension?

Answer 23

The larger the restoring force

Question 24

The larger the tension, the larger the restoring force, so?

Answer 24

The more rapidly the string will accelerate back toward the equilibrium position.

Question 25

What is the equation of frequency?

Answer 25

f= sqrt(T/4mL)
