1.____________, 2._____________, 3._____________

2. During summertime in the country, temperature can get as high as 39°C. What is the speed of sound at this temperature?


Step 1. Given : T=______°C
Step 2. What is asked?=_____________
Step 3. Solve: ​

Answer 1

Answer:

1.Steel, Orange Juice, Neon

2.Step 1: Given: T= 39°C

Step 2: what is asked?

What is the speed of the sound at this temperature?

Step 3: Solve:

During summertime in the country, temperature can get as high as 39°C. What is the speed of sound at this temperature?

Formula: V = 331 m/s + (0.6 m/s/°C) × T

Given: T = 39°C

V = 331 m/s + (0.6 m/s/°C) × 39°C

V = 331 m/s + (0.6 m/s/C) × 39 C

V = 331 m/s + (23.4 m/s)

V = 354.4 m/s

Note: Cancel out "C" in the second expression.
