5. Read the scenarios below. For each of the scenarios, identify the following (you should identify the 3 for EACH of the scenarios):

Control Group Independent Variable Dependent Variable

A. John thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, John counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.

B. Candy notices that her shower is covered in a strange green slime. Her friend Belinda tells her that coconut juice will get rid of the green slime. Candy decides to check this out by spraying half of the shower with coconut juice. She sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.

C. Elisa is working on a science project. Her task is to answer the question: "Does Grow Long (which is a commercial hair product) affect the speed of hair growth?" Her family is willing to volunteer for the experiment.

Which animal would most likely be found in a warm area near the equator that gets around two meters of rainfall per year?

A) Deer
B) Zebra
C) Orangutan
D) Wolf

Answers

Answer:

B) Zebra.

Zebras are well adapted to live in warm areas near the equator and can be found in grasslands and savannas where they graze on grasses. They are also able to tolerate a wide range of rainfall patterns, but are commonly found in areas that receive around 2 meters of rainfall per year.

Deer are more commonly found in cooler areas with forests, and wolves typically live in colder climates such as forests or tundras. Orangutans are primates that live in tropical rainforests and are adapted to living in areas with high rainfall levels. However, they are not typically found in open savannas or grasslands.

The answer is B, Zebra. Zebras live in dry lands like africa, they need to be in warm climates to live comfortably.

Engineers are designing a system by which a falling mass m imparts kinetic energy to a rotating uniform drum to which it is attached by thin, very light wire wrapped around the rim of the drum. There is no appreciable friction in the axle of the drum, and everything starts from rest. This system is being tested on earth, but it is to be used on Mars, where the acceleration due to gravity is 3.71 m/s2. In the earth tests, when m is set to 14.0 kg and allowed to fall through 5.00 m, it gives 150.0 J of kinetic energy to the drum.A. If the system is operated on Mars, through what distance would the 14.0-kg mass have to fall to give the same amount of kinetic energy to the drum?B. How fast would the 14.0-kg mass be moving on Mars just as the drum gained 150.0 J of kinetic energy? the hospitality industry includes three major segments-the commercial segment, on-site segment, and: What role did industrialization play in imperialism Zach bought 200 shares of Goshen stock years ago for $21. 35 per share.
