Question part points submissions used the difference in potential between the accelerating plates of a tv set is about 218 v. if the distance between these plates is 1.29 cm, find the magnitude of the uniform electric field (n/c) in this region. consider entering your answer using scientific notation.

Explanation:

The relationship between electric field strength and potential difference is:

where

E is the electric field strength

V is the potential difference

d is the distance between the plates

Here we have

V = 218 V

d = 1.29 cm = 0.0129 m

So, the electric field is

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.
