<span>The correct option is A. SI unit is the standard measure by which a measurement is made all over the world. Length is a measurement, its SI unit is meter and the tool used to measure it is ruler. The other options are wrong because, temperature is measured in kelvin, weight is measured in kilogram and volume in cubic meter.</span><span />
4. E=mc²
Explanation:
The best approximation of the energy released during a nuclear fusion process can best be determined using the Einstein equation.
In nuclear reactions, mass and energy are equivalent:
E = mc²
E is the energy
m is the mass
c is the speed of light
- In nuclear reactions, some of the mass is converted into the energy.
- Therefore mass is not conserved in such equations.
- This is why they release huge amount of energy.
- From this equation, we know that the more mass loss, the more the energy that would be produced.
- In a fusion reaction, two light nuclei combines to form a heavier one.

Answer:
Carbon:0
Calcium:1
Chloride:2
Hydrogen:0
Oxygen:0
Explanation:
Ca is calcium and there is only one in the compound due to no subscripts. Cl is chloride with a subscript of 2, meaning there are 2 atoms of that element in this compound.
