Answer:
⁴⁰₂₀Ca + ⁰₋₁e
Explanation:
Beta decay:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.
Properties of beta radiations:
The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.
The sheet of aluminium is used to block the beta radiation
⁴⁰₁₉K → ⁴⁰₂₀Ca + ⁰₋₁e
The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.
Answer:
Yes, bikes with larger tires help you go faster.
B: if a person rides a bike with larger tires ,then the person with move faster than on a bike with smaller tires
Explanation:
Bikes with larger wheels cover more distances in one revolution, when compared to bikes with a much smaller wheel, if the wheels are turning at the same revolution per minutes. Although more effort is put into turning a big wheel, when compared to that for a smaller wheel, but it will go faster if you can keep it spinning at the same rate as a small one.
Answer:
It is A).
Explanation:
Silver (Ag) goes from the pure metal to Ag+ losing 1 electron so it is oxidised.
The hydrogen ion gains electrons and is reduced.
