Since specific gravity is a ratio of the density of a solid or liquid to the density of water, all you have to do to find the density, given the specific gravity, is to multiply the specific gravity by the density of water. If you're looking for density in pounds per gallon, you ne...
If you are given aposition function(i.e. the position of an object over time), you’re two steps away, so take thesecond derivativeto finda. You can also workbackwardsto finda. When I say “backwards” here, I’m talking aboutintegrals, which is basically “undoing” the derivative. ...
Using the specific gravity of the substance, calculate its API gravity using the following formula: (141.5/specific gravity) – 131.5. For the exemplar substance, its API gravity would be (141.5/0.5) – 131.5 = 151.5. Things Needed Scale Known volume of petroleum-based liquid Calculator (option...
When you're staring at endless rows of data in an Excel spreadsheet, it's easy for all that information to turn into one blurry mess. Then there's the matter of extracting specific data. In addition to spending what feels like an eternity scrolling through the spreadsheet to find what you...
Weight and Balance Formula Step 2 – Find the Aircraft’s Empty Weight and Moment You can’t do the paperwork until you know which airplane you’ll be flying. The only official source for the empty weight, CG, and moment of the airplane is the official record found in that particular air...
Find the derivative of f(x) = 2\cos(3x+2) What is the FITT formula? Explain the steps to calculate final velocity when many masses collide? How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)?
Using Henrietta's formula, it became very clear to Hubble that this little fuzzy dot in the sky was very far away, way outside of our galaxy. This settled the debate about whether or not our galaxy was the entire universe or not. That little fuzzy spot in the sky that Hubble was look...
It was Huygens who suggested changing "speed" to "velocity" in the formula, which solved the problem. Unlike speed, velocity implies a direction of motion, so the momentum of two objects of the same size traveling the same velocity in opposite directions would be equal to zero. Even though...
It can also be very useful to design word problems where the diamond method can be used to find the answer. Look to examples of gravity and exponential growth for inspiration. However, try to keep solutions and problems limited to integers, even for more experienced students, because diamond ...
Ignore wind resistance to calculate the distance traveled by a bullet using the simple formula: x=v0x2hg Where (v0x) is its starting speed, (h) is the height it's fired from and (g) is the acceleration due to gravity. This formula incorporates drag: x=v0xt−CρAv2t22m Here, (...
