Answer:
10.1 N
Explanation:
Your answer is 10.1 N, I don't actually know how to do it but I hope it helps.
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
Velocity can be calculated using the following rule:
velocity = lambda * frequency where:
velocity is given = 6 km/sec
lambda is the wavelength that we want to calculate
frequency is given = 13 Hz
Substitute with the givens in the above equation to get the wavelength (lambda) as follows:
6 = 13*lambda
wavelength = 6/13 = 0.461538 Km = 461.538 meters
