Ans: Dilute the solution

Explanation:
To decrease the over-saturation, dilute the solution. Dilution is the process of decreasing the solute's concentration in the solution. It is usually done by mixing with more solvent. In other words, to dilute a solution means to add more solvent without the addition of more solute.

The gravitational field of m1 is denoted by g1. Enter an expression for the gravitational field g1 at position la in terms of m1

Andrei [34K]

Answer:

The expression of gravitational field due to mass $m_!$ at a distance $l_a$

Explanation:

We have given mass is $m_1$

Distance of the point where we have to find the gravitational field is $l_a$

Gravitational constant G

We have to find the gravitational filed

Gravitational field is given by $g=\frac{Gm_1}{l_a^2}$

This will be the expression of gravitational field due to mass $m_!$ at a distance $l_a$

belka [17]

Answer:

Informed Consent- The study didn't conform this ethical standard.

Debriefing- The study conforms this ethical standard.

Confidentiality- The study conforms this ethical standard.

Protection from harm- The study conforms this ethical standard.

Explanation:

Informed consent is described as a procedure whereby researchers tend to provide details about specific research they are going to conduct, the risk & benefits involved in the study, different alternatives involved in the procedure, etc.

Debriefing is described as a process that is being conducted in any of the different psychological research encompassing human participants after specific research is completed. The researcher tends to describe the details of the research to the participants.

Confidentiality is described as one of the different code of ethics followed by health workers or psychologists. While practicing confidentiality, a psychologist tends to promise his or her participants that he or she will keep everything a secret whatever is being discussed or shared between both of them.

Protection from harm determines that the psychologists conducting research follows the ethics in which he or she has to protect all the participants from any kind of harm.

An aircraft on it's take-off run has a steady acceleration of 3m/s^2. How much velocity does it gain 10 seconds?

cluponka [151]

Acceleration measures how fast the speed changes over time.

So, over 10s, the aircraft's speed changes by 3 $\frac{m}{ s^{2} }$ * 10s

So, the change is 30 $\frac{m}{s}$

Note that the one of the second units cancels out in the answer.

Which statements about inertia and centripetal force are correct? Check all that apply. Inertia is always present. Inertia cause

allsm [11]

Inertia IS always present. Inertia is NOT the force that causes objects to continue moving in circles, that is centripetal force. Centripetal force is NOT always present. Centripetal force DOES pull objects toward the center of a circle. Inertia and centripetal force DOES cause circular motion. Thank you and eat sand fren ;)
