16) What will happen to C if D is quadrupled, ceteris paribus? * O decrease two-fold increase two-fold decrease four-fold increase four-fold 17) What will happen to C if L is doubled, ceteris paribus? * increase two-fold O remain the same O increase four-fold decrease two-fold18) Using the following equation, which of the following statements is true? * Assume ceteris paribus. AB = DEF C O doubling A will also double B O an increase on E will mean an increase on F as well O a four-fold increase on D will result in E being quartered O reducing C to half its original value will reduce D to half as well For item 19 to 25 (except 22), you are required to submit a digital copy f your solution sheet. You may use a digital whiteboard or a clean sheet of paper as your solution sheet. 19) Convert 500 000 millimeters (mm) to dekameter (dam) * 0.5 dam O 5 dam O 500 dam O 50 dam20) How many seconds are there in 3 days? * 7200 s O 259 200 s O 432 000 s O 120 s 21) Convert 17 feet (ft) to meters (m). Use the conversion factor given below. * 1 ft = 0.3048 m 16.40 m O 0.30 m O 1.52 m O 5.18 m For items 22 to 25, refer to this: According to Newton's Law of Gravitation, the gravitational force F can be computed using the equation below wherein, G is a constant, M and m are the mass of the two interacting objects, and r is the distance between them: GMm F = 7-222) Which pair of variables follow inverse square proportion? (Solution is NOT * needed.) OF and M OF andr M andr O G and M 23) How will F change if variable "m" increases three-fold, ceteris paribus? * decrease three-fold O increase three-fold O decrease nine-fold O increase nine-fold 24) If the distance r between the objects is halved, what will happen to the gravitational force F, ceteris paribus? increase four-fold O decrease four-fold O increase two-fold O decrease two-fold\fFor items 16 and 1?. refer to this: variable (3 is directly proportional to the square of variable L, and inversely.r proportional to variable D
