Answer:
2.88 × 10⁻¹⁸ C
Explanation:
The charge on a proton and electron are the same and it is = 1.6 × 10⁻¹⁹ C
The net charge electric charge of an iron atom = (number of proton × charge on a proton) + ( number of electron × charge on an electron ) = 26 (e) + 8 (-e) = 26 e - 8 e = 18 e = 18 × 1.6 × 10⁻¹⁹ C = 2.88 × 10⁻¹⁸ C
We can solve the problem by using the law of conservation of energy:
- at the beginning, all mechanical energy of the object is just kinetic energy:
, where m is the mass and v is the velocity
- at the point of maximum height, all mechanical energy of the object is just gravitational potential energy:
, where h is the maximum height
Therefore, the conservation of energy becomes:

Re-arranging, we find the maximum height:

Answer:
Energy, 
Explanation:
It is given that,
Mass of matter, m = 1 g = 0.001 Kg
If this matter is completely converted into energy, we need to find the yield. The mass of an object can be converted to energy as :

c = speed of light


So, the energy yield will be
. Hence, this is the required solution.
It depends. The strength of gravitational force between non other than two objects depends on two factors. Mass and distance. The force of gravity and masses exert on each other. Making a consequence if one of the masses are doubled, the force of gravity of the the objects is doubled.
Hope this helps.
