1. Buy a scales.
2. Stand on them.
To find the density of your body, you would measure your body's mass using a scale and then calculate your body's volume by measuring its dimensions and using the appropriate formula (e.g., water displacement method). The density of your body is then calculated by dividing the mass by the volume.
Not a single body is present in this universe without mass but they can be weight less.By definition, mass is the measure of the inertia of a body, so if the body were without mass (as some particles, for example), it would have no inertia.
how would you find the mass of 250 mL of water
You would determine its mass using a mass balance.
Mass of a pony
Nitrogen is usually 3% of your mass so when you half your body mass it would be 1.5%
If you know the density of the rectangular body you can find the volume and the plug it into this equation mass= (density)*(volume) If you have the means you can just submerge the body completely in water and find the volume of the water displaced that will be the mass as waters density is 1 g/cm^3
Using Newton's law of gravitation we can find the gravitational force between the two bodies. Then, using centripetal force equation, we can equate it to the gravitational force to find the velocity of the orbiting body. The velocity can be calculated using the formula v = sqrt(G*M/r), where G is the gravitational constant, M is the mass being orbited, and r is the distance from the center of mass.
Yes. For example, the center of mass of a hollow sphere would be at the empty center of that sphere.
If the force of gravity were to disappear suddenly, the mass of the body would remain the same, as mass is a measure of the amount of matter in an object and does not change. However, the weight of the body would become zero, since weight is the force exerted on an object due to gravity.
Density = Mass/Volume
The best way to find the mass is by scale. The best way to find the volume is to submerge the body in a tank or tub filled partially with water (tank or tub must be equipped with volume measurements). The body must be fully submerged to get an accurate reading. Subtract initial volume from final volume (Vf - Vi = volume of object). That's it. If you are looking for densinty, then Density = Mass/Volume.
