Answer:
he distance to a star can be found by comparing its luminosity to its apparent brightness.
Explanation: A star that is far away will be very dim compared to its luminosity. So it proves that the ratio of its luminosity to apparent brightness will be greater than for a nearby star.
The Seafood Watch is among one of the world's in the industry because of its efficient programs in order to administer the different effects of human intervention in various marine and freshwater ecosystems. In addition to that, these programs promotes speciation in its fishing practices.

Answer:
1a. Both sides of the decay reaction have the same charge.
b. The number of nucleons on both sides are the same.
2. The binding energy of one mole of the atom is 17.172 ×
J.
Explanation:
1a. Considering the two sides of the decay reaction and with respect to the law of conservation of charge, it can be observed that both sides have the same charge. Charge can not be created or destroyed in the process.
b. The number of nucleons on both sides are equal. No nucleon is created or destroyed in the process.
2. Binding energy is the minimum energy required to separate an atom into its nucleons. From Einstein's energy equation;
E = Δm
Where E is the binding energy of the atom, Δm is the mass defect and c is the speed of light.
Given that: Δm = 1.908 g/mol and c = 3 ×
. So that:
E = 1.908 × 
= 1.908 × 9 × 
= 17.172 ×
J
The binding energy of one mole of the atom is 17.172 ×
J.
