Answer:
2m/s²
Explanation:
When an object starts or at its state of rest it has an Initial speed U = 0
Final speed = 6m/s
total time taken for the acceleration = 3s
Acceleration =?
Acceleration is the change in velocity (speed) with time
OR
Time rate of change of velocity
Acceleration = <u>Change in Speed(velocity)</u>
Time taken
Hence,
Acceleration = <u> </u><u> </u><u>V - </u><u>U</u><u> </u><u> </u>
t
a = <u>6</u><u> </u><u>-</u><u> </u><u>0</u>
3
a = <u>6</u><u> </u><u> </u>
3
a = 2m/s²
Add 1 tsp. of vinegar to the canister at a time, filling it almost to the top. You need to add as much vinegar to the canister as possible without the vinegar and the baking soda coming into contact when you later snap the lid onto the canister. Depending on the exact canister, this may be around 5 tsp.
Silicon is the element having a mass of 28.09 g
<u>Explanation</u>:
- Silicon is the element having an atomic mass of 28.09 g / mol. So 28.09 g of silicon contains 6.023
10^23 atoms. One mole of each element can produce one mole of compound.
- The Atomic weight of an element can be determined by the number of protons and neutrons present in one atom of that element. So atomic weight expressed in grams always contain the same number of atoms( 6.023 10^23).
- Avagadro number is the number of atoms of 1 mole of any gas at standard temperature and pressure. It has been determined that 6.023 10^23 atoms of an element are equal to the average atomic mass of that element.
