Answer:
Explanation:
Initial angular velocity ω₁ = 0 , final angular velocity ω₂ = 75.9 rad /s
angle rotated = θ
= 37 x 2π
= 74 π
The formula for angular velocity
ω₂² = ω₁² + 2αθ , α is angular acceleration
75.9² = 0 + 2 α x 74 π
α = 75.9² / 2 x 74 π
= 12.396 rad / s²
Answer:
see explanation
Explanation:
You are missing the chart with the rates and time to do this, however, I wll do it with a similar exercise here, and you only need to replace the procedure with your data:
See the attached table.
From the left we have:
r = 1/2 (50 + 48 + 46 + 44 + 42 + 40) = 135 L/min
From the right we have:
r = 1/2 (48 + 46 +44 + 42 + 40 + 38) = 129 L/min.
And this should be the correct answer. Watch your chart and replace if it's neccesary.
The dependent variable is: <em>"number of vocabulary words subjects can remember"</em>
<h3>
Which is the dependent variable?</h3>
In an experiment, we basically see how changing one variable affects another variable.
In this case, the experiment is:
<em>" if sleep affects the number of vocabulary words subjects can remember."</em>
Then the hours of sleep would be the independent variable (the one that the scientist can change) and the number of vocabulary words subjects can remember is the dependent variable (that depends on the independent variable).
So the correct answer is:
<em>"number of vocabulary words subjects can remember"</em>
