Blood
I learned this in anatomy, and I've taken it twice
From the formula,
v=2πr/T
V(velocity is inversely related to T),so when v increases then time period will decrease.
Option a is correct.
Answer:
The angle between the emergent blue and red light is
Explanation:
We have according to Snell's law
Since medium from which light enter's is air thus
Thus for blue incident light we have
Similarly using the same procedure for red light we have
Thus the absolute value of angle between the refracted blue and red light is
Answer:
A,B,C,D, and F are correct
Explanation:
Answer : Cat will reach tree first.
Explanation :
It is given that,
Total distance between dog and tree is 30 yards. The cat has 10 yards lead. So, the distance between cat and tree is 20 yards.
Speed of cat is 6 Yards/ sec.
Speed of dog is 8 Yards/sec.
speed of cat is,
Now, speed of dog is,
It is clear that, cat is taking less time as compared with dog. So, the cat will reach tree first.
