JudyThe dimensional formula of areal velocity is [T^-1], where T represents time. Areal velocity is defined as the rate of change of area with respect to time and is commonly used in the study of rotational motion or angular velocity. It is expressed in units of m²/s in the International System of Units.

What is areal velocity?
Areal velocity is the rate at which a two-dimensional area is swept out by a moving particle. It is calculated as the cross product of the position vector and the velocity vector of the particle. Areal velocity is important in the study of angular momentum and orbital mechanics.
Why areal velocity is constant in central force?
In central force motion, the centripetal force acts perpendicularly to the velocity, causing the direction of the velocity to change but not its magnitude. As a result, the areal velocity (the rate at which the radius vector sweeps out area in a given amount of time) remains constant. This is a consequence of angular momentum conservation in a central force field.
Why does a can collapse when heated and put in water?
When a sealed can is heated and then put in water, the air inside expands due to the heat. Once the can is immersed in water, the cooling causes the air inside to quickly contract, creating a vacuum. This difference in pressure between the inside and outside of the can leads to its collapse.
How do you use radiesthesia?
Radiesthesia is the practice of using a pendulum or dowsing rod to detect energy fields or vibrations. To use it, hold the tool steady and ask a yes/no question in your mind. The movement of the tool in response to your question can provide insights or answers. Practice and intuition play a big role in getting accurate results.
What is some damage that a thunderstorm woulld cause?
A thunderstorm can cause damage such as lightning strikes resulting in fires or power outages, strong winds leading to fallen trees or structural damage, heavy rainfall causing flooding, and hail damaging crops, vehicles, and buildings.
