**Answer:**

The answer is C. In order to carefully control conditions and confirm or disconfirm a hypothesis about the causes of behavior, one must perform an experiment.

**Explanation:**

Experimental research allows the researcher to control all the variables in order to create the conditions that can confirm or disconfirm a hypothesis. This method aimes to establish a relation of causality between two variables, which means that one variable is generated and determined by the other; this is posible because all of the other variables that can influence it have been controlled.

When a researcher conducts a survey or engages in naturalistic observation, he can’t control the variables, therefore, he can only establish a correlation between two variables, but not of causality.

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies.

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface.

m₁=10 g=0.01 kg is the mass of the pencil

m₂=20 g=0.02 kg is the mass of the eraser

r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h.

So the time for the pencil and eraser to touch is T=1.3449 hours.

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

The statement is equivalent to

120=0 (mod n), meaning that n divides 120.

All divisors of 120 will satisfy the statement because 120 divided by a divisor (factor) will leave a remainder of 0.

Factors of 120 are:

n={1,2,3,4,5,6,8,10,12,15,20,24,30,40,60,120}, |n|=16.

You can count how many such values of n there are, and try to check that each one satisfies 127=7 mod n.

Let’s assume that this question is referring to every digital calendar ever made. As in, even those made on devices without internet connectivity or any other fancy features that we utilize with many digital calendars today.

If a planning device that came with a digital calendar didn’t have internet connectivity, it wouldn’t be able to be connected to the cloud. Back when these devices were around, it wasn’t even plausible to store things like calendar events and contacts in what we know as the “cloud”. Also, these devices probably had to be hardwired to a computer and new software had to be downloaded to them, so the updates weren’t automatic. Archaic, right?

Also, consider the fact that even reputable websites/companies such as Google with Google Calendars or Apple with iCalendar will never go without their malfunctions or threats. Sometimes, these websites can be hacked and the data that they contain can be compromised, especially if they’re stored on the cloud. Also, even though it’s not realistic, Google or Apple could one day decide to completely get rid of their calendar programs altogether. So, this means that digital calendars are definitely able to be destroyed or lost.

That just leaves “They can be used anywhere”. This is true, even with those archaic devices specifically used for scheduling events and such. Nowadays, you have your phone and possibly a laptop on you at all times, which will likely have a calendar on it as a stock application. So, I think this is your answer.

Hope this helped you out! 🙂

The Contribution Margin per unit (CM) can be calculated

from the difference of Selling Price per unit (SP) and Total Expenses per unit

(TE).

First, let’s calculate the value of SP:

SP = Sales / Units sold

SP = $1,043,400 / 22,200 units sold

SP = $47

Second, calculate all expenses:

Direct materials per unit = $234,948 / 27,970 units

manufactured = $8.4

Direct labor per unit = $131,459 / 27,970 units

manufactured = $4.7

Variable manufacturing overhead per unit = $240,542 / 27,970

units manufactured = $8.6

Variable selling expenses per unit = $113,220 / 22,200

units sold = $5.1

TE = $26.8

Therefore the CM is:

CM = SP – TE

CM = $47 – $26.8

**CM = $20.2 per unit**

**Rochelle’s erratic memory of her mediocre performance is most likely due to ****HINDSIGHT BIAS (Answer).**

Hindsight bias refers to “an eye for predicting some events in life before they have even happened.” It is that leaning many people have to see events as more predictable than they are.

It is also common to listen to people saying that they knew or had the feeling about the outcome of an event. It is the same that happened with Rochelle, once she realized her real grades, she remembered how poorly she did in college; it says: ” She then started telling everyone she remembers being a pretty poor student”.

**Answer:**

3 hours.

**Step-by-step explanation:**

Let x be the time taken by shoe repairman to repair one pair.

We have been given that his assistant, who takes twice as long to repair a pair of shoes. So time taken by his assistant to repair one pair of shoes would be 2x.

The number of pair of shoes repaired by repairman in one hour would be .

The number of pair of shoes repaired by assistant in one hour would be .

We have been given that together they can fix 16 pairs of shoes in an eight-hour day. We can represent this information in an equation as:

Let us have a common denominator.

Upon cross multiplying our equation we will get,

**Therefore, it take 3 hours for the repairman to fix one pair of shoes by himself.**

No, although some literature is, such as Heart of Darkness by Joseph Conrad or Waiting for Godot by Samuel Beckett. These types of works were most popular in the late 19th century and early 20th century. But, there are other types of literature that are fueled by the writer’s own life (i.e., Edgar Allan Poe who often wrote poems inspired by his late wife, Virginia Clemm, Sylvia Plath who wrote The Bell Jar based off of her own mental illness experience, and Everything, Everything by Nicola Yoon who wrote the novel based off of her daughter.) The most popular literature is based on what the author is most passionate about. Whether it is politics, activism, romanticism, etc., as long as it is charged by a driving force, it is literature.

**Answer:**

The correct answer is **helium 4. **

**Explanation:**

A positively charged particle, which comprises two protons and two neutrons is called an alpha particle. There is a similarity between the alpha particle and a helium atom as helium atom also possess mass number, that is, no of protons plus no of neutrons as 4, and atomic number, that is, number of protons a 2.

Therefore, it can be said that an alpha particle is also considered as a nucleus of helium isotope.

**Answer:**

The correct answer is D. Fifty years of effort by suffragists secured approval of the Nineteenth Amendment.

**Explanation:**

The Nineteenth Amendment was developed to extend suffrage to women. It was proposed on June 4, 1919 and was ratified on August 18, 1920.

The amendment was the culmination of the work of the feminist movement in favor of women’s suffrage, which started in 1848 with the Seneca Falls Convention, 71 years earlier. Another of the activist groups that supported the feminist struggle was the Silent Sentinels that protested in front of the White House to raise awareness about the problem.
