It depends on the length of the pendulum and the strength of gravitational pull acting upon the pendulum.
Hope this helps!

<h3>
Explanation:</h3>
_______________
h=7,5 m
g=10 m/s²
ρ=1000 kg/m³
_______________
p - ?
_______________
p=ρgh=1000 kg/m³ · 10 m/s² · 7,5 m = 75000 Pa = 75 kPa
Answer:
x = 2
Explanation:
if it was -7 = the square root of both 2x-9 together, it would be false.
if it was square root of just 2x in the equation, the answer is:
x = 2
°°°°°°°°°
-7 = √2x - 9
-√2x = -9 + 7
√-2x = -2
√2x = 2
2x = 4
x = 2
<span>F = ma
</span>Ff = μ*Fn
<span>Fn = Fw
</span>Fw = mg
<span>So we have: </span>
<span>Ff = μmg </span>
<span>And </span>
<span>Ff = ma </span>
<span>So... </span>
<span>μmg = ma </span><span> </span>
<span>μg = a </span>
<span>And we can solve for the acceleration: </span>
<span>(0.15)(9.81 m/s²) = a </span>
<span>a = 1.47 m/s² </span>
