What can be the maximum duration of totality for a solar eclipse? (a) 12.5 minutes (b) 7 minutes 40 seconds

Theta=wt+1/2alpha Tsq. By this we will get Theta=200. For first 10 and last 10 sec theta will be same therefore =400. And for 10 sec of middle is alpha ×100= 400. Total =400+400=800rad

(c) They will be together at the starting point after the L.C.M of 36, 48 and 42 L.C.M. of 36, 48, 42 = 1008 seconds

The athlete’s fitness index score is calculated with the help of following formula. Fitness index score = (100 × test duration in seconds) divided by (2 × sums of heartbeats...

(c) Diamond ring is observed during solar eclipse, only along the peripheral regions of the totality trail.

(d) The sequencing of the entire gensome (the totallity of all genes) was completed in 1996 of Plasmodium vivax.

(c) Diamond ring is observed during solar eclipse, only along the peripheral regions of the totality trail.

(a) The size of the shadow of the moon on the earth is small as compared to the cross section of the earth 

L.C.M. of 48, 72, 108 = 2 x 2 x 2 x 2 x 3 x 3 x 3 = 432 sec. After 432 seconds, the lights change simultaneously. 432 second =...
