Answer:D
Explanation:
Given
Same force is applied to each ball such that all have different masses
and Force is given by the product of mass and acceleration
So acceleration of ball A
acceleration of ball B
acceleration of ball C
acceleration of ball D
It is clear that acceleration of ball D is least.
the wavelength equation is
speed (of light in this
case)= wavelength (m) x frequency
3x10^8m/s / .07m = f
frequency= 4 285 714 286
hertz
b) Total distance= 4.8 km
(4,800 m)
Speed = 3x10^8 m/s
d=st
t= d/s
t= 4,800 m/3x10^8m/s
<span>t= 1x10^-5 seconds</span>
Answer:
b
Explanation:
b. increased frequency and severity of forest fires
Because of the Global warming the forest fires have increased drastically. The recent fire in Amazon rain forest is an example of this. These burning forests emit a large amount of CO2 yet again and further causing more global warming. According a a recent data it is estimated that forest fire emit about 8 million tons of CO2 in the atmosphere in last 20 years. In,2017 total global CO2 emission has reached to 32.5 billion tons, according to IEA.
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.
