Answer:
Shown from explanation.
Explanation:
The resonant frequency is related by the formula;
Fo= 1/2π√(K/M)
Where Fo is resonant frequency
M is mass
K is the spring constant
From the expression above;
When K is increased frequency would increases since frequency is directly proportional to spring constant.
Similarly when the mass is increased the frequency decreases since frequency is inversely proportional to the mass.
Amplitude is a property of a wave and so the frequency stays same.
Recall that
<em>v</em>² - <em>u</em>² = 2 <em>a</em> ∆<em>x</em>
where <em>u</em> and <em>v</em> are initial and final velocities, respectively; <em>a</em> is acceleration; and ∆<em>x</em> is the distance traveled (because the skater moves in only one direction).
So we have
(5.8 m/s)² - (8.8 m/s)² = 2 <em>a</em> (6.0 m)
<em>a</em> = ((5.8 m/s)² - (8.8 m/s)²) / (12 m)
<em>a</em> = -3.65 m/s²
Answer:
43 m\s in the 10 seconds?
Explanation:
A single pulley changes the direction of the effort, but it has
no mechanical advantage. The output force is the same as
the input force, so we'd say that the mechanical advantage is 1.
If there are two pulleys, with the rope going up and down and
around between them several times on its way from the effort
to the load, an arrangement that I think is called 'block and tackle',
then the mechanical advantage turns out to be the number of
strands of rope that are supporting the load.
Answer:
I feel like its the second one but I'm not completely sure..
