Derek and Wes take a photograph of a lake at the same angle and the same time of day. Derek's picture comes out with crisp edges around objects in the photo. Wes's picture seems to blur the outlines of objects due to glare. Which wave phenomenon best explains the differences between the pictures?
a. diffraction
b. dispersion
c. reflection
d. polarization

0.11 m/s and 0.28 m/s should be correct

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.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
