Answer:
The gravitational potential energy of that rock is 174371.4 J.
Explanation:
Given
To determine
We need to find the gravitational potential energy of the rock
We know that the potential energy of a body is termed as the stored energy due to its position.
One kind of energy comes from Earth's gravity — Gravitational potential energy (GPE).
Gravitational potential energy (GPE) can be determined using the formula
where
- is the mass
- is the gravitational acceleration which is equal to g = 9.8 m/s²
- is the height
- GPE is the Gravitational potential energy
now substituting m = 59.31, h = 300 and g = 9.8
J
Therefore, the gravitational potential energy of that rock is 174371.4 J.
Answer:
<u>Informed Consent- The study didn't conform this ethical standard.</u>
<u>Debriefing- The study conforms this ethical standard.</u>
<u>Confidentiality- The study conforms this ethical standard.</u>
<u>Protection from harm- The study conforms this ethical standard.</u>
Explanation:
<u>Informed consent</u> 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.
<u>Debriefing </u>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.
<u>Confidentiality</u> 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.
<u>Protection from harm</u> 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.
In the single-slit experiment, the displacement of the minima of the diffraction pattern on the screen is given by
(1)
where
n is the order of the minimum
y is the displacement of the nth-minimum from the center of the diffraction pattern
is the light's wavelength
D is the distance of the screen from the slit
a is the width of the slit
In our problem,
while the distance between the first and the fifth minima is
(2)
If we use the formula to rewrite
, eq.(2) becomes
Which we can solve to find a, the width of the slit:
Answer:
A
Explanation:
the higher the specific heat, the more insulator like it is. the lower the heat capacity, the more conductor like.
