Answer 2

2||(h/g)^1/2

Where h-height of water column in each tube

Question 3

Ball of mass m oscillating in the neck of an air chamber T=

Answer 3

2|| (mV/PA^2)^1/2

Question 4

If a person sitting on a swing suddenly stands up

Answer 4

Time period decrease

Question 5

If pendulum is kept in a car sliding down the slope T=

Answer 5

2|| (l/gcos@)^1/2

Question 6

T of springs in series

Answer 6

T = (T1^2 + T2^2)^1/2

Question 7

T if springs in parallel

Answer 7

T = T1T2 / (T1^2 + T2^2)^1/2

Question 8

Simple pendulum with long length

Answer 8

T = 2|| (lRe/ (l+Re)g)^1/2

If l=infinity

T= 2|| (Re/g)^1/2
