D. The number of wave that pass a point in a given amount of time
Answer:
45.03681 m/s²
Explanation:
= Buoyant force
W = Weight of the balloon
= Density of air = 1.23 kg/m³
= Density of balloon = 0.22 kg/m³
= Volume of air
= Volume of balloon
g = Acceleration due to gravity = 9.81 m/s²
The net force acting on the balloon is
The equation is
The acceleration of the balloon is 45.03681 m/s²
The formula we can use in
this case would be:
v = sqrt (T / (m / l))
Where,
v = is the velocity of the
transverse wave = unknown (?)
T = is the tension on the
rope = 500 N
m = is the mass of the
rope = 60.0 g = 0.06 kg
l = is the
length of the rope = 2.00 m
Substituting the given values into the equation to search
for the speed v:
v = sqrt (500 N/(0.06 kg /2 m))
v = sqrt (500 * 2 / 0.06)
v = sqrt (16,666.67)
<span>v = 129.10 m/s</span>
