How does solubility apply to food science ?
Typical backyard ants often create a network of chemical trails for guidance. Extending outward from the nest, a trail branches (bifurcates) repeatedly, with 60° between the branches. If a roaming ant chances upon a trail, it can tell the way to the nest at any branch point: If it is moving away from the nest, it has two choices of path requiring a small turn in its travel direction, either 30° leftward or 30° rightward. If it is moving toward the nest, it has only one such choice. Given figure shows a typical ant trail, with lettered straight sections of 2.0 cm length and symmetric bifurcation of 60°. Path “v” is parallel to the y axis. What are the (a) magnitude and (b) angle (relative to the positive direction of the superimposed x axis) of an ant’s displacement from the nest (find it in the figure) if the ant enters the trail at point A? What are the (c) magnitude and (d) angle if it enters at point B? Nest is located at the end of the segment “w”.
You are driving toward a traffic signal when it turns yellow. Your speed is the legal speed limit of V0 = 55 km/h; your best deceleration rate has the magnitude a = 5.18 m/s2. Your best reaction time to begin braking is T = 0.75 s. To avoid having the front of your car enter the intersection after the light turns red, should you brake
to a stop or continue to move at 55 km/h if the distance to the intersection and the duration of the yellow light are (a) 40 m and 2.8 s, and (b) 32 m and 1.8 s? Give an answer of brake, continue, either (if either strategy works), or neither (if neither strategy works and the yellow duration is inappropriate).
Harvard Bridge, which connects MIT with its fraternities across the Charles River, has a length of 364.4 Smoots plus one ear. The unit of one Smoot is based on the length of Oliver Reed Smoot, Jr., class of 1962, who was carried or dragged length by length across the bridge so that other pledge members of the Lambda Chi Alpha fraternity could mark off (with paint) 1-Smoot lengths along the bridge. The marks have been repainted biannually by fraternity pledges since the initial measurement, usually during times of traffic congestion so that the police cannot easily interfere. (Presumably, the police were originally upset because the Smoot is not an SI base unit, but these days they seem to have accepted the unit.) Figure given below shows three parallel paths, measured in Smoots (S), Willies (W), and Zeldas (Z). What is the length of 50.0 Smoots in (a) Willies and (b) Zeldas?
Write a program to create 2 single dimension arrays in order to store 10 numbers respectively, then merge the values of both the arrays into third array so that the values of first array and second array will be alternate to each other, then display values of the merged array.
Alternate means third array will carry values of first and second arrays as follows:
c[0]=a[0]
c[1]=b[0]
c[2]=a[1]
c[3]=b[1]
c[4]=a[2]
c[5]=b[2]
c[6]=a[3]
c[7]=b[3]

The orbit of a satellite was at an altitude of about 400 km and an inclination of 51°. It's starting mass was 50kg. What is the gravitational force
Lawrence performs a survey to determine the average number of minutes of exercise seventh-grade athletes get in one week. He gets a list of sports and the seventh-grade students participating in each sport. He then chooses 10 people from each list to complete the survey. How can Lawrence’s sample be improved to be more representative of the population?

4g of H2 diffuses from a vessel in 5 minutes. How much SO2 will diffuse from same vessel in 5 minutes?
A research is being done on a particular species of bear on an animal reserve territory. Initially, there are 50 bears on the reserve. After t years the number of bears, n, satisfies the differential equation "dn" / "dt" = 1 / "20k" n(k-n), where k are constant.
a.) By using saperable viarable, show that the general solution of the differential equation is n = 200 / 1 +3e-0.05t given that k = 200 [14 marks]
b.) In 2012, the population of the bears in the territory are 200. Estimate the population of the bears that will be able to survive after 2022. [3 marks]
