A) \[1\text{ }2\text{ }3\text{ }4\text{ }5\]
B) \[2\text{ }1\text{ }3\text{ }4\text{ }5\]
C) \[3\text{ }2\text{ }4\text{ }1\text{ }5\]
D) \[3\text{ }2\text{ }1\text{ }4\text{ }5\]
Correct Answer: D
Solution :
: (1) In seconds pendulum, T= 2 sec (2) For human pulse,\[n=\frac{72}{60}\]pulse per sec \[\therefore \] \[T=\frac{60}{72}=0.83sec\] (3) For alternating current, frequency = 50 Hz \[\therefore \] \[T=\frac{1}{50}=0.02\,\sec \] (4) Fop-earths rotation about its own axis, T = 24 hours (5) For moon moving round earth,\[T=27.3\]days Ascending order\[=3,\text{ }2,\text{ }1,\text{ }4,\text{ }5\]You need to login to perform this action.
