How we know, for calculate density, we can use the formule:
<u>Where:</u>
p = Density = ?
m = Mass = 57,9 g
v = Volume = 3 cm³
Let's replace according we information:
p = 57,9 g / 3 cm³
p = 19,3 g/cm³
The density of the metal bar is <u>19,3 g/cm³.</u>
<u></u>
¿Good luck?
Kepler's second law of planetary motion<span> describes the speed of a </span>planet<span> traveling in an elliptical orbit around the sun. It states that a line between the sun and the </span>planetsweeps equal areas in equal times. Thus, the speed of theplanet<span> increases as it nears the sun and decreases as it recedes from the sun.</span>
