The given graph shows how the level of pollution changes in an area over a time period. Which of the following can be most likely concluded from the given graph?


ATrees were cut in large numbers in that area at point P.
BA new factory was set up in the area at point Q.
CThe interval R-S shows that people started recycling waste and switched to public transport instead of using their personal transports.
DNone of these

b

Ans 8:

The answer is b

Ans 9:

Class : Class 5
The answer cannot be B because the timeline Q-R is a decrease in pollution whereas if a factory was set up in point Q.Q-R would be an increase of pollution and not a decrease.In point P trees were cut and because of that P-Q is an increase in pollution and not a decrease .So,the answer is not B but A.

But why not D? If trees were cut down at point P, then why is the point at lowest pollution?

The correct answer is option A

In my opinion, the answer should be option (A) instead of option (B). On the Richter scale (which is a non-linear scale), the power of an earthquake increases by 10 with every consequent number. Thus, an earthquake of 2 on the Richter scale is 10 times more powerful than an earthquake of 1 on the Richter scale. Thus, an earthquake of 8 on the Richter scale is more powerful than an earthquake of 6 on the Richter scale, by a factor of 10⁸⁻⁶, or 10². Thus, an earthquake of 8 on the Richter scale is 100 times more powerful than an earthquake of 6 on the Richter scale.

Hi friend. The ans is (A) 100 because on richter scale the magnitude is increased ten times every number. for example 2 is 10 times 1 on richter scale.

D

Ans 4:

Class : Class 8
The correct answer should be D. Because temperature of air increases, density decreases and so, frequency of sound increases. But, according to me, it may or may not affect the wavelength, but the time period will definitely decrease. The options are a bit confusing.....

Ans 5:

Class : Class 9
no it can not be option d as temperature has no effect on frequency. Wheather temperature increases or decreases frequency remains unchanged. So, the answer could be either time period or frequency.

Ans 6:

Class : Class 8
d

Ans 7:

Class : Class 8
The answer is D. If wavelength changes , then frequency and time period will also change. Wavelength is inversely propotional to frequency and directly propotional to time period.
