Answer:

Explanation:

I'm not sure about the different types (I think one was selective bias) but they can ruin research if the person decides to use there bias. Example: if I'm trying to prove such and such movie is good and I'm doing research on it. I might choose to do a poll. Because I want to prove that this movie is the best I will pick the people who I know liked the movie. That is being biased.

Three types of bias can be distinguished: information bias, selection bias, and confounding. These three types of bias and their potential solutions are discussed using various examples.

Bias can damage research, if the researcher chooses to allow his bias to distort the measurements and observations or their interpretation. When faculty are biased about individual students in their courses, they may grade some students more or less favorably than others, which is not fair to any of the students.

What is the electric force on a proton 2.5 fm from the surface of the nucleus? hint: treat the spherical nucleus as a point char

Whitepunk [10]

In this case, you need the formula below where:

F = force
k = coulombs constant 8.99 x10^{9} N.m^{2} . C^{-2}
q1 = electric charge 1
q2 = electric charge 2
r = the distance between the charges

$F = k((q1.q2)/r^{2})$

pls note: make sure your units are correct (in meters etc, not fm (<em>femto-meters</em>)).

Curiously, this question doesn't tell you what atom you are next to the nucleus of. Different numbers of protons in the nucleus of the atom will make for vastly different forces in your answer...

The henry's law constant for n2 is 6. 2×10−4matm at 25∘c. what pressure of nitrogen is needed to maintain a n2 concentration of

hodyreva [135]

The pressure of nitrogen which is needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).

<h3>What is pressure? </h3>

It is defined as the continuous physical force applied on or against an object by something which is in contact with it.

It is also defined as the force per unit area.

<h3>What is henry's law? </h3>

The henry law constant is thr ratio of the partial pressure of compound in air to the concentration of compound in water at given temperature.

C= kp

where,

C is the concentration of compound = 0.53m

k is the henry constant = 6. 2×10−4matm

p is the pressure of compound

By substituting all the value we get,

C = 6. 2×10−4 × p

0.53 = 6. 2×10−4 × p

p = 0.53/6. 2×10−4

p = 3.2 × 10^(4)

Thus we find that the pressure needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).

A molecule moves down its concentration gradient using a transport protein in the plasma membrane. This is an example of

nydimaria [60]

Since they move down their concentration gradient through a transport protein, they can release energy as a result of chemiosmosis. One example is GLUT1 which moves glucose down its concentration gradient into the cell.

star a and star b have measured stellar parallax of 0.58 arc second and 0.73 arc second, respectively. which star is closer?

goldenfox [79]

Star B is closer than star A, because 1/ 0.58 = 1.72 pc, while 1/.73 = 1.36 pc.

<h3>What is stellar parallax and distance measurement using stellar parallax?</h3>

To calculate the distances to nearby stars, astronomers employ a phenomenon known as parallax. The apparent displacement of an object due to a change in the viewer's point of view is known as parallax. The distances between close stars can be calculated using this phenomenon. A nearer star will seem to move against the farther-off background stars as the Earth revolves around the Sun. By measuring a star's position once, then again six months later, astronomers can establish the apparent shift in location of that star. The apparent motion of the star is referred to as stellar parallax.

A straightforward correlation exists between the distance of a star and parallax angle:

$d=\frac{1}{p}$

The distance d and parallax angle p are both measured in parsecs and arcseconds, respectively.

Stellar parallax of star A= 0.58 arcseconds

Stellar parallax of star B= 0.73 arcseconds

So, on applying the formula,

The distance of the star A= 1.72pc

And the distance of the star B= 1.36pc

Therefore, star B is closer than star A.
