Answer:
11.6532 x 10⁻¹¹ J or 7.3 MeV is given off
Explanation:
Mass of an alpha particle = 4.0026u, ∴ mass of three = 12.0078u
Find the difference in mass.
Mass of three alpha - Mass of Carbon nucleus
12.0078u - 12u = 0.0078u
Since 1u = 1.66 x 10⁻²⁷ kg
Therefore, 0.0078u = 1.2948 x 10⁻²⁷
Now that we know Mass(m) = 1.2948 x 10⁻²⁷ and Speed (c) 3 x 10⁸ m²s⁻²
Formular for Energy ==> E₀ = mc²
E = (1.2948 x 10⁻²⁷) (3 x 10⁸ m²s⁻²)²
E = (1.2948 x 10⁻²⁷) (9 x 10¹⁶) J
E = 11.6532 x 10⁻¹¹ J
Or, if you need your energy in MeV
1 MeV = 1.60x10⁻¹³ J
Just do the conversion by dividing 11.6532 x 10⁻¹¹ J by 1.60x10⁻¹³ J
It will give you 7.3 MeV
For an individual to reduce his or her carbon footprint, they can:
- Reduce the use of automobile
- switch other renewable energy sources like solar energy
Hydrogen fuels are clean energy sources and should replace fossil fuels.
Carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases.
<h3>What is a carbon footprint?</h3>
A carbon footprint is the measure of the total amount of greenhouse gases that are emitted into the atmosphere each year by an individual.
Greenhouse gases are responsible for global warming.
For an individual to reduce his or her carbon footprint, they can:
- Reduce the use of automobile
- switch other renewable energy sources like solar energy
Hydrogen fuels are able to replace fossil fuels as they are clean energy sources.
An individual's carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases released.
In conclusion, greenhouse gases are responsible for global warming.

Answer:
D
Explanation:
descriptive, because scientists are writing down the observations but not making comparisons.
False because their are single cell organisms
Answer:second class lever needs less force to lift a load
Explanation: because the load is between the fulcrum/pivot point and the force. The fulcrum is far away from the force
