SCIENCE SOUND:
What is a example of each medium that sound can travel in

Answers

Answer 1

Answer: you're listening to energy making a journey. It sets off from somewhere inside from the clock, travels through the air, and arrives some time later in your ears. It's a little bit like waves, they start out from a place where the wind is blowing on the water (the original source of the energy, like the bell or buzzer inside your alarm clock), travel over the ocean surface (that's the medium that allow the waves to travel), and eventually wash up on the beach (similar to sounds entering your ears). There is one crucially important difference between waves bumping over the sea and the sound waves that reach our ears. Sea waves travel as up-and-down vibrations: the water moves up and down (without really moving anywhere) as the energy in the wave travels forward. Waves like this are called transverse waves. That just means the water vibrates at right angles to the direction in which the wave travels. Sound waves work in a completely different way. As a sound wave moves forward, it makes the air bunch together in some places and spread out in others.

Arianna buys 5 boxes of granola bars. Each box contains 12 granola bars Arianna eats 4 bars Jason writes a numerical expression to represent the situation His expression: (12-4)x5 has a mistake PART A:
Explain Jason's mistake

PART B:
Write an expression to show how many granola bars are left, and then solve it

Answers

Answer: PART A: Explain Jason's mistake. Instead of Jason multiplying the 5 boxes of granola bars by 12 granola bars in each box to get the total number of bars then subtract the 4 bars Arianna ate from the total number of bars in the 5 boxes.

Part B: 5boxes multiply by 12 granola bars equals to 60 granola bars. Subtract 4 granola bars from 60 granola bars equals to 56 granola bars left.

5x12= 60

60-4=56

Explanation:

12 granola bars × 5 boxes =60 granola bars - 4 granola Ariana eats = 54 are left
