The solution is in the attached file below
Explanation:
Answer:
Generally with successive half-life a new element is formed from the decayed nuclei:
isotope - daughter nucleus has same no. of protons (same atomic number) so the same element is formed in the decay
isotone - daughter nucleus has same number of neutrons so the atomic number has changed and a new element is formed (new atomic number)
isobar - daughter nucleus has same mass number - this could be an example of beta decay where the decayed nucleus has the same mass number but loses a neutron and gains a proton because of the lost electron and a new element is formed with the atomic number increases by 1
Example:
U238 Uranium - alpha to Th234
Th234 Thorium - 2 beta to U234 (back to U but atomic mass less by 4)
U234 Uranium - alpha to Th230
Th230 Thorium - alpha to Ra226
etc. but during beta decay (electron loss) a neutron is lost and a proton gained (answer a)
I think it depend on the curvature of the reflective surface, right? if it is an Mirror, then the angles should mirror itself.
Answer:
option (A)
Explanation:
The a body having rest mass is mo is moving with velocity v which is of the order of velocity of light in vacuum, so the mass of the body increases. According to the formula
As the velocity increases, the mass m of the body increases. As the velocity of the object is equal to the velocity of light in vacuum, then the mass of the body becomes infinite.
Yes, because cell phones use scientific structure to build.
