The current loop lies flat on a horizontal surface. Facing the loop from the top, the current moves in a clockwise direction. Which way does the magnetic field point outside the loop? a) The field points down.
b) The field points down.
c) The field points to the left.
d) The field points up
e) The field points to the right

e

Explanation:

the field points to the right

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

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.
