The mass of Mg-24 is 24.30506 amu, it contains 12 protons and 12 neutrons.
Theoretical mass of Mg-24:
The theoretical mass of Mg-24 is:
Hydrogen atom mass = 12 × 1.00728 amu = 12.0874 amu
Neutron mass = 12 x 1.008665 amu = 12.104 amu
Theoretical mass = Hydrogen atom mass + Neutron mass = 24.1913 amu
Note that the mass defect is:
Mass defect = Actual mass - Theoretical mass : 24.30506 amu- 24.1913 amu= 0.11376 amu
Calculating the binding energy per nucleon:
So approximately 4.41294 Mev/necleon
A negative ion is a atom that has an extra electron, but the same # of protons
Answer:
Fm - W = 0 1) true. Imams must separate, to match the two forces, you reach equilibrium
Explanation:
When the magnet is exchanged for a stronger one, but of the same weight, the equilibrium equation
Fm - W = 0
Fm = W
If the weight of the imam is the same, the magnetite force must decrease, so that it will occupy the magnets must be separated a greater distance, according to the formula
Fm = Km m ’m / r²
Where Km is value 10⁻⁷ N s²/C², r is the distance between the poles
Let's review the proposed results
1) true. Imams must separate, to match the two forces, you reach equilibrium
2) False. In this case the weight would be less than the magnetic force
3) False The magnetic force increases and equilibrium is not reached
Answer:
Explanation:
The Work-Kinetic Energy Theorem states that the work done on a particle of mass "m", equals the particle's change in Kinetic Energy (final Kinetic Energy of the particle "
" minus the initial Kinetic energy of the particle "
"), and it is expressed as:
where we have used the explicit form of the KE of a particle of mass m and velocity 
. Of course, 
stands for the final velocity of the particle, and 
for the particle's initial velocity.
Answer:
B
Explanation:this is not physics
