A simple method based on the moment of forces and Archimedes’ principle is described for finding density without measuring the mass and volume of an object. The method involves balancing two unknown objects of masses M1 and M2 on each side of a pivot on a metre rule and measuring their corresponding moment arms.

Density= Mass/Volume where mass is that for just the liquid (you must subtract out the mass of the graduated cylinder).

In order to find the density, I simply divided the mass found by the volume found. For example, 30.0035 g divided by 30.425 mL equals 0.9861 g/mL. To find the average density, I added the three densities I found, then divided that total by three to find the average.

The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.

How to calculate Density Of Two Liquids? Density Of Two Liquids is the resulting density of the mixture formed when two liquids are mixed is calculated using density_of_two_liquids = (Mass of Liquid A+Mass of Liquid B)/((Mass of Liquid A/Density of Liquid A)+(Mass of Liquid B/Density of Liquid B)).

Density is the mass per unit volume. It can be measured in several ways. The most accurate way to calculate the density of any solid, liquid or gas is to divide its mass in kilograms by its volume (length × width × height) in cubic metres. The unit for density is kg/m 3.

You take the mass of each and multiply by its respective ratio. A: (0.3 x X) – then add the mass of component B multiplied by its ratio in the sample (0.7 x Y) and thus you have the average mass. Divide this average mass by the volume of the sample to get density.

Density is defined as the mass per unit volume of a substance or mixture of substances. Density for an entire mixture cannot be calculated for a heterogeneous mixture, since the particles in the mixture are not uniformly distributed, and the mass changes throughout the volume.

Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9. BMI applies to most adults 18-65 years.

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d).

1 J = 1 N m. Work can be either positive or negative: if the force has a component in the same direction as the displacement of the object, the force is doing positive work. If the force has a component in the direction opposite to the displacement, the force does negative work.

When force and displacement are in the same direction, the work performed on an object is said to be positive work. Example: When a body moves on the horizontal surface, force and displacement act in the forward path. The work is done in this case known as Positive work.

The definition of a positive is a good thing, or a result greater than zero, or something that represents an affirmation. An example of a positive is an item on a list of good things about losing your job. An example of a positive is a result on a pregnancy test saying that you’re pregnant.

1) A simple example of zero work is when you stand holding a bag in your hands and do not move it. Your hands apply a force on the bag to balance the force of gravity exerted on it but since there is no displacement of the bag, the work done on it by you (your force) and also the gravity is zero.

Positive work follows when the force has a component parallel to the displacement. Positive work adds energy to a system. Negative work follows when the force has a component opposite or against the displacement. Negative work removes or dissipates energy from the system.
