Answer:
4
Explanation:
Waves that are squished have higher frequency. It has short wavelength.
Answer:
Part A:
to two significant figures
Part B:
to two significant figures
Part C:
to two significant figures
Explanation:
Given that :
mass of the hydrogen = 0.30 g
the molar mass of hydrogen gas molecule = 2 g/mol
we all know that:
number of moles = mass/molar mass
number of moles = 0.30 g /2 g/mol
number of moles = 0.15 mol
For low temperature between the range of 50 K to 100 K, the specific heat at constant volume for a diatomic gas molecule = 
For Part A:




to two significant figures
Part B. For hot temperature, 




to two significant figures
Part C. For an extremely hot temperature, 




to two significant figures

The position of the first bird is

The position of the second bird is

Let θ = the angle between the net displacement vector for the two birds.
By definition,



Similarly,
|b| = 4.025
Therefore

Answer: 36.9°
