∙ 15y ago
These quantities are referred to as physical quantities in the field of physics. They are measurable properties that can be described using mathematical values and units. Area and volume are examples of scalar physical quantities, while velocity is an example of a vector physical quantity.

Volume with given velocity?
The volume of a moving fluid can be calculated by multiplying the cross-sectional area of the flow by the velocity of the fluid. The formula is: Volume = Area x Velocity. This equation is commonly used in fluid dynamics to determine the flow rate or throughput of a fluid system.
Is mm squared density or volume?
Neither. "mm squared" refers to an area, as it is a unit of measure for two-dimensional surfaces. Density is mass per unit volume, and volume is the amount of space occupied by an object.
Why velocity increases as you increase the area in kitchen taps during opening the tap?
Increasing the area of the tap opening allows more water to flow through, which results in an increase in the velocity of the water exiting the tap. This is due to the principle of conservation of mass, where the same volume of water must pass through the larger opening in a shorter time, leading to an increase in velocity.
What is the relation between velocity and flow rate?
Velocity is the speed at which a fluid moves past a specific point, while flow rate is the volume of fluid that passes through that point per unit time. The flow rate is directly related to velocity through the equation Q = A * V, where Q is the flow rate, A is the cross-sectional area of the flow, and V is the velocity of the fluid.
Name the two physical quantities which can be obtained from the velocity-time graph?
Acceleration and displacement can be obtained from the velocity-time graph. Acceleration is the rate of change of velocity, which can be found as the slope of the velocity-time graph. Displacement can be determined by finding the area under the velocity-time graph, as it represents the distance traveled by an object.
What are 4 derived quantities?
Some examples of derived quantities are velocity (which is derived from distance and time), acceleration (derived from velocity and time), density (derived from mass and volume), and pressure (derived from force and area).
How do you find volume if velocity and area are known?
You cannot. Velocity has nothing to do with volume and information on area, by itself, is not enough to determine the volume.
What is the surface to volume area ration of 6micrometers?
None.There is no such thing as a surface to volume area ration!

What is used to measure derived?
They are used to measure quantities that are not basic. Length, for example, is a basic unit, but area and volume are not so derived units will be used to measure area and volume.
Why area is called a derived quantity?
Derived quantities are quantities that are calculated from two or more measurements. They include area, volume, and density. The area of a rectangular surface is calculated as its length multiplied by its width. The volume of a rectangular solid is calculated as the product of its length, width, and height.
Volume with given velocity?
The volume of a moving fluid can be calculated by multiplying the cross-sectional area of the flow by the velocity of the fluid. The formula is: Volume = Area x Velocity. This equation is commonly used in fluid dynamics to determine the flow rate or throughput of a fluid system.
What derived unit is used to measure?

What is derive quantities with explanation?
Derived quantities are physical quantities that are calculated from one or more base quantities using mathematical operations. These derived quantities are not independent and depend on the base quantities for their definition. Examples include velocity (calculated from distance and time) and acceleration (calculated from velocity and time).
What is difference between base quantities and derived quantities?
Basic or fundamental quantities are seven in number. They cannot be derived right from one another. Hence they are independent. They are length, mass, time, electric current, temperature, quantity of substance, luminosity. Two sub are there. They are plane angle and solid angle. But derived are many in number. Just by the name they are derived right from the fundamental. They are area, volume, velocity, acceleration, force, momentum, magnetic induction, electric field, dipole moment, pressure, density etc etc
7 fundamental and derive quantity for math and physical quantity?
7 fundamental quantities=Area, volume, density , speed/velocity , acceleration , force , work done. Derivation :Area=length x breadth = m x m = 2m (meter square)Volume=length x breadth x height = m x m x m = 3m (meter cube)Density=mass / volume = kg / m³ = kg/m³Velocity=displacement / time = m/sAcceleration=final velocity x initial velocity / time = m/s²Force=mass x acceleration = N (newton)Work Done=force x distance = J (joule)
How are length area and volume related in terms of the three dimensions of space?
length refers to a linwhich is one dimensional. Area refers to a square which is two dimensional. Volume refers to a cube which is three dimensional. There is no fourth dimension. The zero dimension is a point with no mass.
What is the difference between base quentities and derived quantities?
Base quantities are fundamental physical quantities that are independent and cannot be defined in terms of other quantities, such as length, mass, and time. Derived quantities are defined in terms of base quantities by mathematical operations, such as velocity (m/s) being derived from dividing distance (m) by time (s).
