This problem is requiring us to find the half life of the element. We can solve this problem by using the equation
as shown: A=Aoe^-(ln2/t)T where A is the final amount (5 kilogram), Ao is
the initial amount (40.0 kilogram), t is the half-life (required) and lastly T
time elapsed (4.0 years). Plug in the values in the equation and you should
get 1.33 years as the half life.

Answer:Replacing Hubble's Main Computer NASA performed a battery of mechanical, electrical, radiation and thermal tests to guarantee that the computer would survive the trip to orbit, withstand bombardment by cosmic and solar radiation and work flawlessly in the extreme temperatures of space for the rest of Hubble's life.
Explanation:
Answer:
1.Nucleus 2.Cytoplasm 3. Vacuoles 4.chloroplasts 5. Body Cell 6. Cell Wall 7. Membrane
Explanation:
- The nucleus is the control center of the cell.
- The jelly-like substance inside the cell is called as cytoplasm.
- They are found in both animal and plant cells but are much larger in plant cells.
- In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
- The rest of the air is mostly nitrogen (79%). Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar.
- Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
