31.	find theacceleration due to gravity in a mine depth of 640m if the value at the surface is 9.8m/s.The radius of the earth is 6400km
Answer» The depth, d = 640 m The radius of the earth, R = 6400 km = 6.4×106 m The value of acceleration due to gravity at the SURFACE of the earth, g = 9.8 m/s2 Therefore, the acceleration due to gravity at the depth of 640 m

31.

find theacceleration due to gravity in a mine depth of 640m if the value at the surface is 9.8m/s.The radius of the earth is 6400km

Answer»

The depth, d = 640 m

The radius of the earth, R = 6400 km = 6.4×106 m

The value of acceleration due to gravity at the SURFACE of the earth, g = 9.8 m/s2

Therefore, the acceleration due to gravity at the depth of 640 m

32.	Define the terms (a) blind spot on the retina. (b) persistence of vision of human eye
Answer» Blind Spot: The blind spot is an area on the RETINA that does not have any nerve cells. Therefore, an image that FALLS on this region will not be seen. Persistence Of Vision: The eye and the brain retain the inpression of an object's image formed on the retina for a SHORT PERIOD of time. The impression persists for 1/16th of a second. Due to this, the images you see just before MIXES with the image you are watching at that moment. This illusion type of thing is called persistence of vision.

Answer»

EXPLANATION:

Wf=420rpm

=420×2pie÷60 rad/sec.

alpha=5.5rad/sec^2

wf^2=2alpha×theta

196pie^2=11theta

theta is ALSO = 2pieN

so,196pie^2=11×2×pie×N

therefore by SOLVING we GET N=28

38.	Calculate the number of molecules in 1.195 g of chloroform. (CHCl3).(At. mass, H = 1u, C = 12u, Cl = 35.5 u)
Answer» Heya mate,Here is ur answer Molar MASS of CHCl3 = Mass of C+ Mass of H + 3× Mass of Cl Molar Mass of CHCl3 = 12+1+3×35.5 Molar mass of CHCl3 = 12+1+106.5 Molar mass of CHCl3 = 119.5 g. We KNOW that each mole of any compound has fixed number of 6.022×10^23 molecules. Here 6.022×10^23 is known as " Avagadro Number " . So, 119.5 g of CHCl3 has = 6.022 × 10^23 molecules 1 gm of CHCl3 has = 6.022×10^3 / 119.5 molecules. 1.195 g of CHCl3 has = $\frac{6.022 \times 10 {}^{23} }{119.5} \times 1.195$ $= \frac{6.022 \times 10 {}^{23} \times 10 }{1195 \times 1000} \times 1195$ $= \frac{6.022 \times 10 {}^{24} }{10 {}^{3} }$ $= 6.022 \times 10 {}^{21}$ So, 1.195 g of CHCl3 has 6.022 ×10^21 molecules. ====================== Warm REGARDS @Laughterqueen Be Brainly ✌✌

41.	Why are multiple images formed when 2 mirrors are placed at right angles to each to other?Plz don't copy from Google.....And answer fastly nd correctly
Answer» We get many images of the objects because the image formed by one mirror acts as an object for the SECOND mirror. Further images of an image are also formed. This continues till no more reflection by either mirror is possible. This phenomenon is referred to as multiple reflection. So, we get 3 images by the PROCESS of N = 360/Theta( The angle at which mirrors are placed ) - 1. Therefore, 360/90 - 1 = 4 - 1 = 3. HOPE THIS HELPS......... :D CHEERS,,,,,,
