Answer:
Mass = 386 kg
Explanation:
<u><em>Density = Mass / Volume</em></u>
Mass = Density × Volume
Where D = 19300 kg/m³ , V = 0.02 m³
<em>Putting the given in the above formula</em>
Mass = 19300 × 0.02
Mass = 386 kg
When you square the "year" of each planet and divide it by the cube of its distance, or axis from the sun, the number would be the same for all the planets
Answer:
if somthing is warm or if somthing moves it usally has energy
Kinetic energy is directly proportional to the square of their velocities... so if velocity has been increased 3 times, increase in K.E would be: 3^2 = 9
In short, Your Answer would be: KE2 = 9 * KE1
Hope this helps!
