Albert Einstein.
The Equation is
E = m*c^(2)
That is
E is Energy
m is mass
c^2 is speed of light squared.
take a measuring cylinder and pour some water into it . tie a piece of stone to a thread and lower it into it tillit is completely immersed.note the reading(v1).now tie a piece of wood and a piece of stone together and lower them into the water till both are comletely immersed. note the reading on the cylinder again(v2).calculate the volume of piece of wood using fomula(v2-v1) from:samit kafle kawasoti,Nepal
Mathematically, terminal velocity-without considering buoyancy effects-is given bywhereVt = terminal velocity,m = mass of the falling object,g = acceleration due to gravity,Cd = drag coefficient,ρ = density of the fluid through which the object is falling, andA = projected area of the object.Anand Kumar GuptaResearch ScholarCSIR Laboratory
Newtons (N) are the units of force. Kilograms (kg) are the units of mass. The force due to the acceleration of gravity, (g=9.8 m/s/s on Earth.) is the weight. W=mg If the weight is 19.6 N on Earth, then the mass is 2 kg. So, the question should have been stated, "If the weight of an object is 19.6 newtons on the surface of the Earth, then what is the mass of the object?"
