Write about 10 instruments which are used to measure different physical quantities i.e. -
mass, volume, time and temperature
The unit of a physical quantity in physics is a standardized way to express and measure that quantity. Units give the quantity a numerical value and specify the scale at which it is being measured. Units are essential for consistency and clarity when communicating about physical quantities.
The basic quantities in physics are mass (kg), length (m), time (s), electric current (A), temperature (K), amount of substance (mol), and luminous intensity (cd).
To administer 250,000 units of Penicillin from a solution containing 1,000,000 units in 2 cc, you would need to calculate the proportion: (250,000 units / 1,000,000 units) * 2 cc = 0.5 cc. Therefore, you would administer 0.5 cc of the solution.
Having both kilograms and moles as units for amount of a substance is useful because kilograms give a macroscopic perspective by measuring the mass of the substance, while moles provide a more microscopic perspective by quantifying the number of particles (atoms, molecules, ions, etc.) present. This duality allows for easy conversion between the two units, enabling scientists to express quantities in a way that is both practical and meaningful in various contexts.
Yes, a quantity can have units but still be dimensionless if the units cancel out when they are raised to the power of 0. For example, specific volume (volume per mass) has units of m^3/kg, but when you divide volume by mass, the units cancel out and it becomes dimensionless.

It is acceptable to work with either molar quantities expressed in grams or average molecular quantities expressed in atomic mass units because both methods give the same relative proportions of elements in a compound. The molar quantities expressed in grams allow for direct measurement and calculations based on mass, while the average molecular quantities expressed in atomic mass units provide a more theoretical approach in determining percentage composition.
it is the utilization of human and physical resources
There are vast quantities of students that answer questions by plagiarizing examples from the internet.
Oh, honey, the relationship of quantities is just like a dysfunctional family reunion - you've got addition, subtraction, multiplication, and division all fighting for attention. They all work together in their own special ways to give you the final answer. Just remember, they may not always get along, but they sure know how to make math interesting.
Give water to drink. You may give small quantities in installments if that is necessary.

A vector quantity refers to a physical quantity that has both magnitude and direction. Some examples of vector quantities include velocity (speed and direction), force (magnitude and direction), and displacement (distance and direction).
