First, let's find the angle of inclination using the tangent function.
sin θ = opposite/hypotenuse = 1 m/2 m
θ = 30°
Assuming the ramp is frictionless, the force balance is:
F = mgsinθ = ma
Cancelling out m,
a = gsinθ = (9.81 m/s²)(sin 30°) = 4.905 m/s²
Using the equation for rectilinear motion at constant acceleration,
x = v₀t + 0.5at²
2 m = (6 m/s)(t) + 0.5(4.905 m/s²)(t²)
Solving for tm
t = 0.297 seconds
Using the equation for acceleration:
a = (v - v₀)/t
4.905 m/s² = (v - 6 m/s)/0.297 s
Solving for v,
v = 7.46 m/s
Explanation:
Silent mutations occur when the change of a single DNA nucleotide within a protein-coding portion of a gene does not affect the sequence of amino acids that make up the gene's protein.

Answer: The results will tell us about the correctness of hypothesis.
<u>Explanation:</u>
The Hypothesis is that explanation which is used as a starting of any investigation. The Hypothesis can or cannot be correct. We can test the hypothesis with scientific research.
Now a student can make conclusions about the hypothesis based on the results obtained. If results are the same as the hypothesis it means that our proposed explanation i.e hypothesis was correct but if the result differs than it means the hypothesis was not correct.
Answer:
Explanation:
Fish decreased algal biomass and directly increased all biogeochemical rates. The relative importance of the different abiotic ecosystem properties varied by process; however, FBOM and substrata size were important for most rates.
