The quantity of a gas is typically measured in moles, which is a unit of measurement that represents the amount of a substance. Another common unit for measuring the quantity of a gas is liters, which represents the volume of the gas.
What represents 1 percent of the Earth's mass?
The ocean represents about 0.02% of the Earth's mass, making up the largest portion at that scale.
What is the product of the mass and velocity of an object?
The product of mass and velocity gives the momentum of an object. Momentum is a vector quantity that represents an object's motion. It is calculated by multiplying the mass of the object by its velocity.
Flow rate of mass is vector or scalar?
The flow rate of mass is a scalar quantity since it only has magnitude and no direction associated with it. It represents the amount of mass passing through a given area per unit time.
Which physical quantity is analogous to mass?
In the context of electricity and magnetism, electric charge is analogous to mass in that it represents the amount of "stuff" that an object possesses with respect to electromagnetism. Just as mass is a measure of inertia and the tendency to resist changes in motion, charge is a measure of the influence an object exerts in an electric or magnetic field.
