As, per the buoyancy force,the volume that the balloon should have is 2863
What is buoyancy force?
Air buoyancy is the upward force exerted on an object by the air that is displaced by object. Air buoyancy is responsible for the buoyancy created by the displaced air.
= -Vρg , where V= volume of the object
ρ = density of the object
g = acceleration due to gravity
= buoyant force
The buoyancy force must be equal to the total load lifted
ρ × V × g + 269 + 2910 = ρ × V × g
0.179 × V + 3179 = 1.29 V
0.179V + 3179 = 1.29V
0.179V- 1.29V = - 3179
1.11V = 3179
On solving , we get
V = 2863
Therefore, the volume that the balloon should have is 2863.

From the given motions, let's determine the example which is not an example of a wave motion.
Wave motion can be defined as the transfer of energy from one point to another without the actual transfer of matter between the points.
From the given examples, the example which which we can say does not represent a wave motion is: a person dancing.
An earthquake’s energy travelling through the core of the planet is an example of wave motion since the energy travels through one point to the other.
A tsunami event occurring after an earthquake is also an example of a wave motion.
A vibrating Slinky showing crests and troughs is an example of wave motion.
While the sound of a tuba is an example of a sound wave,
Therefore, the example which does NOT represent a wave motion is a person dancing.
ANSWER:
A). A person dancing.
Answer:
The potential energy increases if the orbital radius increases.
Explanation:
The orbital radius of the electron increases means the distance from the nucleus of the hydrogen atom increase.
The nucleus is positively charged .
The potential energy is given by P.E = -
where Z is the atomic number
r is the radius
The negative sign indicates that the electron which is revolving is bound to nucleus.
As the radius and potential energy are inversely proportional it is clear that when <em>radius increase</em> the<em> potential energy become less negative </em>which means the potential energy increases when the orbital radius increase.
<u>The Weight </u>is a vector whose magnitude is the product of the mass m of the object and the magnitude of the local gravitational acceleration. Its always directed toward the center of the Earth.
