Give an example of a system that has energy.
Answer:
Aerobic Energy System
Explanation:
Answer:
Digestive system. It contains chemical energy. The digestive system breaks down food. Food contains chemical energy. To break down the food, the digestive system contains enzymes. Enzymes have kinetic energy to move and break down the food. They are biological catalysts. They transfer to the thermal energy store since in order to break down food at the fastest rate, they need to be at an optimum temperature.
I'm not sure if it's correct, but I'll provide some energy stores to give you inspiration:
Kinetic energy
Chemical energy
Nuclear energy
Gravitational potential energy
Elastic potential energy
Thermal energy

What is the number of copper atom in one naira coin which weight is 7.3g a sum of the material is 86%
Answer:
5.9x10²² atoms of Cu are in one naira coin
Explanation:
To solve this question we need to find the mass of Copper. Then, using its molar mass (Cu = 63.546g/mol) we must find the moles of Cu and its atoms using Avogadro's number:
Mass Cu:
7.3g * 86% = 6.278g is the mass of Cu.
Moles Cu:
6.278g * (1mol / 63.546g) = 0.099moles Cu
Atoms Cu:
0.099moles Cu * (6.022x10²³atoms / 1mol) =

What risks does nuclear waste pose to Earth or the sun or outer space?
Answer:
It could pollute other planets. Nuclear waste might be attracted by the gravitational pull of the sun and disintegrate there instead. The waste storage spacecraft could crash into a planet, moon, or another astronomical body. It could be dangerous for other life forms out there.
Explanation:
b) Explain the importance of photosynthesis for plants.
Answer:
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.

Identify the daughter isotope in this nuclear reaction: Superscript 222 subscript 88 upper R a right arrow superscript 218 subscript 86 R n plus superscript 4 subscript 2 upper H e. Which is the daughter isotope? Superscript 218 subscript 86 R n. Superscript 4 subscript 2 upper H e. Superscript 222 subscript 88 upper R a.
The daughter isotope which is present in the given radioactive decay is ²¹⁸₈₆R.
What is daughter isotope?A daughter isotope is the isotope that remains following the radioactive decay of an original isotope.
In the question parent nuclei is given that ²²²₈₈R, and given chemical equation is:
²²²₈₈R → ²¹⁸₈₆R + ⁴₂He
In the above equation ²¹⁸₈₆R is the daughter nuclei and ⁴₂He is the emitted particle or rays.
Hence ²¹⁸₈₆R is the daughter isotope.

If I have 6.02 x 10^23 cars how many moles of cars do I have?
Answer:
1 mole of car
Explanation:
One mole of a substance is said to be equal to 6.02 × 10^23 atoms, which is Avagadro's number or constant. In other words, 1mole of every substance = 6.02 × 10^23 atoms. Hence, the number of moles in a substance can be calculated by dividing the number of atoms contained in that substance (nA) by 6.02 × 10^23.
According to this question, If I have 6.02 x 10^23 cars, this means that I have:
6.02 x 10^23 cars ÷ 6.02 x 10^23
= 6.02 ÷ 6.02 × 10^(23-23)
= 1 × 1^0
= 1mole of car

.What is the KE of a baseball that has a mass of 100 kg and is traveling at 5 m/s?
Answer:
1250joules
Explanation:
The kinetic energy is energy in motion and it's formula is
KE =1/2MV^2
M represent mass which is 100Kg.
V represent velocity which is 5m/s
Therefore, KE = 1/2×100×5× 5
= 50 × 25
KE= 1250joules
