What is the rest energy of an electron, given its mass is 9.11 × 10-31 kg?​

The rest energy of an electron is its mass times c squared. That's 9.11 times 10 to the minus 31 kilograms times 2.998 times 10 to the 8 meters per second squared giving 8.19 times 10 to the minus 14 joules.

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.

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
