Assuming the earth and the sun to be perfect spheres,
Volume of the sphere = 4/3 * pi * (r**3)
Volume of the earth = 4/3 * pi * ((4000*1.609 km)**3) = 1.116 E 12 km3
Volume of the Sun= 4/3 * pi * ((7 E 5 km)**3) = 1.436 E 18 km3
Density = mass /volume
Density of earth = 6 E 24 kg / 1.116 E 12 km3 = 5.376 E 12 [kg/km3]
Density of Sun= 2 E 30 kg / 1.436 E 18 km3 = 1.392 E 12 [kg/km3]
Density of earth / Density of Sun =
5.376 E 12 [kg/km3] / 1.392 E 12 [kg/km3] = 3.86
when the aim is to show electron distributions in shells.
hope this helps :)
Answer:
Explanation:
Let assume that system is conservative. From application of the Principle of Energy Conservation, it is noticed that initial linear kinetic energy must be equal to the gravitational energy at the top of the circle. That is to say:
Where .
Electric Charge Conserved means that no case has ever been found.
Explanation:
- The electric power can neither be built nor destroyed.
- But it can be saved and used whenever required, the closed-circuit system is movement of charges tends to current, which means the flow of charge, but the charges are still existing in the closed system, the charges in the isolated does not changes and it is always filled with charges, only on power trigger the charges moves.
- Found in material like copper, iron, etc.
- This is based on the rule of conservation of power that defines that, power can neither be built nor it can be destroyed, but it can be transformed into one order to another order.
- Hence this case is found in all electrical circuits.
- This fails in nonconductors like wooden, glass and plastic with no flow of charges in them.
Explanation:
A resistor is 'Ohmic' if as voltage across the resistor is increased, a graph of voltage versus current shows a straight line.
