Answer:
Hypothesis:
When a scientist see lizard behaving in this way in each rainystrom in the desert, he can make a hypothesis about the lizard’s way of drinking water. He can say that lizard spread its legs to wide body. In this way it catches and carry water in microscopic channels on its body. These channels lead water to its mouth and it drinks this water by opening and closing mouth continuously.
Answer:
455.9 Hz, Flat
Explanation:
The beat frequency is basically the difference between the frequency of the B4 note and the frequency of the A4 tuning fork. This means the B4 note is 15.9 Hz off of 440Hz, and 67.4 Hz off of 525.3 Hz. As B4 is between the two notes, it would make sense to find its frequency by adding 15.9 to 440 and subtracting 67.4 from 523.3, both if which give us a frequency 455.9 Hz for the B4 key. This is because the note doesn't change for the different turning forks so both differences should result in the same frequency. Because the note should be 493.9 frequency but instead has a frequency of 455.9 Hz, it is flat because the frequency is lower than it is supposed to be.

Answer:
option (B)
Explanation:
mass of proton, m = m
charge of proton, q = e
Time period, T = T
Initially the speed of proton is v.
The time period of the proton when it is moving in magnetic field perpendicular to the direction of magnetic field is given by
Where, r be the radius of circular path.
The relation between r and the speed v is given by
Where, B be the strength of magnetic field. Substitute this value of r in the expression of time period
Here, we observe that the expression for the time period is independent to v and r so, as we change the velocity, the time period remains same.
Answer:
Furthermore, the Pythagorean theorem works when the two added vectors are at right angles to one another - such as for adding a north vector and an east vector.
The article is not found here but surveys are important because they are representative samples of a population.
<h3>What is a survey?</h3>
A survey is a useful tool based on population samples, which is used to make statistical analyses in a given investigation.
Differences in surveys are generally due to small sample sizes, which may lead to errors in the analysis of data.
In conclusion, the article is not found here but surveys are important because they are representative samples of a population.
