A rotating mass of air with minimum pressure in its center is known as a cyclone. In meteorology, cyclones are characterized by low atmospheric pressure at their core, leading to a system of winds that rotate around this center. The rotation is typically counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere, driven by the Coriolis effect. Cyclones can be associated with severe weather, including heavy rain and strong winds.

What is moment of inertia of partially filled tube with liquid and set horizontal rotating about a vertical axis passing through its center?
The moment of inertia of a partially filled tube with liquid rotating horizontally about a vertical axis through its center is affected by the distribution of mass within the tube. The moment of inertia depends on the shape of the tube, the mass of the liquid, the radius of the tube, and the distance of the liquid's center of mass from the rotation axis. The parallel axis theorem can be used to calculate the moment of inertia of the tube and liquid system.
Why is there a low mass limit for stars?
Stars are powered by nucliar fussion. There is minimum pressure and temperature requirement in order to start the process. So to became Star the object has to have enought mass to increase its internal temperature and pressure.
Why is the pressure in the center of the earth greater than the pressure in the mantle?
Because towards the center of the earth, there is more mass on top of it, so there is more pressure. All of the other layers, and the stuff on top of the earth is pushing down on it from all sides. For the mantle, its only the stuff on the top of the earth that is putting pressure on it.
Does an atom have center of gravity?
Everything with mass has a center of gravity although in an atomic scale these numbers are very small and in newtons laws state all things with mass put forces on anything else with mass so it might not be possible to balance an atom on top of another atom but everything has a center of gravity that has mass or weight no matter how big or small
Does the moments of Inertia change if center of mass change?
No, the moment of inertia of an object does not change with a change in its center of mass. The moment of inertia depends on the mass distribution and shape of an object, not its center of mass.
Balance and unbalance?
In mechanical engineering, Balance means it is the inability to maintain the center of gravity of a body within the base of support with minimum postural sway. Unbalance means uneven distribution of mass in a rotating body. Balancing means the process of improving uneven distribution of mass in a rotating body.
How do center of mass and center of pressure affect a rocket?
The center of mass is the average position of the mass of the rocket, affecting stability and control, while the center of pressure is the average location where aerodynamic forces act, influencing the aerodynamic behavior of the rocket. The relative positions of the center of mass and center of pressure determine the stability of the rocket during flight.
Why does the moment of inertia increase when mass is distributed farther from the center of a rotating object?
The moment of inertia increases when mass is distributed farther from the center of a rotating object because the mass is located at a greater distance from the axis of rotation. This results in a larger rotational inertia, making it harder to change the object's rotational motion.
What is the moment of inertia about the instantaneous center in a rotating rigid body?
The moment of inertia about the instantaneous center in a rotating rigid body is a measure of how difficult it is to change the body's rotational motion around that point. It depends on the mass distribution and shape of the body.
Where is the earths center of gravity and why it spin as it moves through space?
The earth's center of gravity is the center of the earth, or the center of the mass with the mass being the earth. The earth spins as it moves through space on account of sun's gravitational forces and because there is nothing in space to get in the way or stop the earth from rotating.
What analogy is cyclone too?
A cyclone can be likened to a spinning top, as it is a rotating mass of air that swirls around a low-pressure center. Just like a spinning top, a cyclone's motion is characterized by a circular pattern, with the energy being concentrated at its core.
What is the center of mass of a bottle rocket?
The center of mass of a bottle rocket is typically located around the middle of the rocket body where most of the mass is concentrated. It is important for stable flight that the center of mass is positioned below the center of pressure to ensure the rocket can maintain the correct orientation during flight.
What happens to pressure as you move outward from earths core?
Pressure decreases as you move outward from the Earth's core. The farther you are from the center, the less mass you will have pressing down on your location. Mass that is underneath you (or in other words, closer to the center) does not press on you, only mass that is above will add to the pressure where you are.
What is moment of inertia of partially filled tube with liquid and set horizontal rotating about a vertical axis passing through its center?
The moment of inertia of a partially filled tube with liquid rotating horizontally about a vertical axis through its center is affected by the distribution of mass within the tube. The moment of inertia depends on the shape of the tube, the mass of the liquid, the radius of the tube, and the distance of the liquid's center of mass from the rotation axis. The parallel axis theorem can be used to calculate the moment of inertia of the tube and liquid system.
How far apart should the center of pressure and the center of mass be in a bottled rocket?
For stability, it is recommended to have the center of pressure (CP) slightly behind the center of mass (CM). The distance between CP and CM, referred to as stability margin, should typically be around 1-2 body tube diameters in front of the CM for a stable flight of a bottle rocket.
Applications of center of pressure?
As the intensity of pressure increases with depth so for an inclined surface CP is bellow CG. Center of gravity : a point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the center of mass.
How do pressure change as you go from the center of Earth?
Pressure increases as you go deeper into the Earth due to the weight of the overlying material pushing down. At the center of the Earth, the pressure is at its maximum, as the entire mass of the Earth is acting to compress the material at that point.
