C is a correct answer. Because at the bottom, a moving pendulum have the fewest potential energy
Fresh water has a variety of different sources on Earth which includes rivers, lakes, streams, rain water, etc.
One of the fresh water sources is a Lagoon which is a permanent shallow body of water which is separated from the larger water bodies by a natural barrier such as reefs or islands.
Reportedly, almost <u>311 plant species</u> are found to be grown in the Atanasovsko Lake lagoon, out of which the Marsh samphire, reed, vicia and sea wormwood are a few to name.
Answer:
The stickiness in the inner walls allows them to be easily coated with the desired antigens, this translates in the use of a smaller amount of antigen. If the walls weren't sticky there's a possibility the antigen won't stick to them and therefore the result of the ELISA can be a false negative.
I hope you find this information useful and interesting! Good luck!
The two possible distances that you might infer your friends swam while the lights were out are 25 m and 75 m.
Answer:
Explanation:
So you have to measure the distance covered by your friend in a time gap of 86 s. And the average velocity is given as 0.29 m/s.
Then as per the mathematical calculation of velocity, distance can be measured as the product of velocity with time interval.
Distance = Velocity × Time Interval
Distance = 0.29 m/s×86 s = 24.94 m.
So based on this calculation, one of the possible distance inferred by you will be 24.94 m.
Another possible distance can be guessed from the statements provided. So if the length of pool is 50 m, then covering halfway in opposite direction to his starting direction means completion of one full length i.e., 50 m and then halfway of that 50 m which is 25m, so totally 50 +25 = 75 m.
So in other way, we can assume that your friend has covered 75 m distance during the light out.
Thus, the two possible distances that you might infer your friends swam while the lights were out are 25 m and 75 m.
