How are surface waves similar to transverse waves?
Nataly [62]
In longitudinal and transverse waves<span>, all the particles in the entire bulk of the medium move in a parallel and a perpendicular direction (respectively) relative to the direction of energy transport. In a </span>surface wave, it is only the particles at the surface<span> of the medium that undergo the circular motion.</span>

A hydrogen-filled balloon is used to lift a 120-kg stone off the ground. The basket holding the stone has a mass of 10.0 kg . Pa
Kaylis [27]

Answer:

Radius, r = 2.88 meters.

Explanation:

It is given that,

A hydrogen-filled balloon is used to lift a 120-kg stone off the ground, m₁ = 120 kg

The basket holding the stone has a mass of 10.0 kg, m₂ = 10 kg

Mass density of air, d=1.29\ kg/m^3

We know that buoyant force is equal to the weight of liquid displaced i.e.

B=mg

B=(m_1+m_2)g

B=(120+10)\times 9.8

B = 1274 N

Also, buoyant force is given by :

B=dVg

B=\dfrac{4\pi r^3dg}{3}

r^3=\dfrac{3B}{4\pi dg}

r^3=\dfrac{3\times 1274}{4\pi \times 1.29\times 9.8}

r=2.88\ m

So, the minimum radius R of the balloon be in order to lift the stone off the ground is 2.88 meters. Hence, this is the required solution.
