Answer:
Explanation:
Density = Mass / Volume = 850 / 40*10*5 = 0.425 g /cm^3
Answer:
a. λ = 647.2 nm
b. I₀ 9.36 x 10⁻⁵
Explanation:
Given:
β = 56.0 rad , θ = 3.09 ° , γ = 0.170 mm = 0.170 x 10⁻³ m
a.
The wavelength of the radiation can be find using
β = 2 π / γ * sin θ
λ = [ 2π * γ * sin θ ] / β
λ = [ 2π * 0.107 x 10⁻³m * sin (3.09°) ] / 56.0 rad
λ = 647.14 x 10⁻⁹ m ⇒ λ = 647.2 nm
b.
The intensity of the central maximum I₀
I = I₀ (4 / β² ) * sin ( β / 2)²
I = I₀ (4 / 56.0²) * [ sin (56.0 /2) ]²
I = I₀ 9.36 x 10⁻⁵
Im thinking a and d but if its just one answer im thinking mostly a
Present. NOT SURE IF THIS IS EVEN RIGHT!! I JUST GUESSED AND THOUGHT
1. If Maggie gives her cat an unfair advantage, her experimental results will be biased.
Explanation:
Maggie using her cat in the experiment to test for intelligence gives the cat an unfair advantage, her experimental results will be biased.
- Due to her emotional attachment with the cat, the experimental results will be skewed to portraying her cat as intelligence.
- This is not a good experiment to carry out.
- Such an experiment should be carried out with an unknown cat.
