Acertain radioactive (parent) nucleus transforms to a different (daughter) nucleus by emitting an electron and a neutrino. the parent was at rest at the origin of an xy coordinate system. the electron moves away from the origin with linear momentum (-5.6 x 10-22 kg m/s) ; the neutrino moves away from the origin with linear momentum (-6.9 x 10-23 kg m/s) . what are (a) the magnitude and (b) angle (from the +x axis) of the linear momentum of the daughter nucleus? (c) if the daughter nucleus has a mass of 8.7 x 10-26 kg, what is its kinetic energy?

correct it is c.) b b

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
