Using Density to Calculate Mass or Volume of a Sphere Suppose you have a cannonball made completely of iron. You can look up the density of iron in a table: 7.8 g/cm3. You weigh the cannonball and find it weighs 20 lbs. You now have enough information to calculate its volume, so ju...
To calculate the object's density, divide its mass by its volume. The equation for density is "density = mass/volume." Things Needed Triple-Beam Balance Graduated Cylinder TL;DR (Too Long; Didn't Read) If the object is a sphere or another type of regular object, you may be able to ...
In fact, it is reported that Archimedes used this trick to calculate the volume of his own body. By stepping into a bath, he noticed that the water level rose, and he understood that the volume of water that was displaced was equal to the volume of his submerged body. He shouted out:...
How to calculate the volume of an inclined cone Find the mass of the disk (x -1)^2 2+ y^2 \leq 1 if the density is \rho (x,y) = 1+x. How to find the volume of right circular cylinder Find the volume inside x^2 + y^2 + z^2 = a^2 and (x - (\frac{a}{2}))^...
Astronomers observe a similar effect with stars due to Earth's orbit. By comparing star positions six months apart, they measure this parallax angle (Θ). Using Θ and Earth's orbit radius (R), they calculate a star's distance (D) as: D = RCotΘ. This is effective for stars within ...

You then use measurements of the movement of objects around a suspected black hole to calculate the black hole's mass. What you look for is a star or a disk of gas that is behaving as though there were a large mass nearby. For example, if a visible star or disk of gas has a "...
Assuming the Earth to be a sphere of uniform mass density, how much would a body weight half way down to the centre of the Earth, if it weighed300Non the surface of Earth. View Solution Free Ncert Solutions English Medium NCERT Solutions ...
Convert 1.5 square miles (mi^2) to square meters (m^2). Use the conversion factor: 1,609.34 meter = 1 mile. What is the density in g/mL of a sphere with a diameter of 4.00 cm and a mass of 1.35 g? What are the units used to measure different types of mass in the metric sys...
On February 8, 2022, approximately 40 of the 49 Starlink satellites were reported to have lost altitude, leading to atmospheric re-entry. SpaceX reported that the orbital decay on Starlink satellites was considered to be linked to a geomagnetic storm tha
