PLS ANSWER FAST WILL GIVE BRAINLEST THIS IS TIMED TEST!!! Answer using mass m= F divided by a

Also use kilograms [kg]

A 7.5 force is applied to a football generating an initial acceleration of 15 m/ s2. Calculate the mass of the football

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

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.
