The planet would stay in the same orbit but start revolving faster.
(Its year would get shorter.)
Answer:
The wavelength is 3500 nm.
Explanation:
d= 
n= 1
θ= 30°
λ= unknown
Solution:
d sinθ = nλ
λ = 
λ = 3500 nm
The ardor determines the result of a reaction.
[formula A]+[formula B]—> [formula C]
Here, the arrow signifies that when adding formula A and B, you get formula C. An arrow can also go both directions.
[formulaA]+[form.B]<—>[formulaC]+[form.D]
Here, the double sided arrows means that adding formulas A and B will give you C and D, and adding formulas C and D will give you A and B.
Answer:
v₀ = 13.24 m / s
Explanation:
Let's use Newton's second law to find the average acceleration during the crash
F = m a
. a = F / m
a = 8000/73
a = 109.59 m / s²
Now we can use the kinematic equations to find the initial velocity, since when the velocity stops it is zero (v = 0)
v² = v₀² - 2 a x
v₀² = 2 a x
v₀ = √ 2 a x
v₀ = √ (2 109.59 0.80)
v₀ = 13.24 m / s
