    Pendulum Value
AI Thread Summary
The accepted value of 2.01 for a pendulum's period is derived from the formula T = 2π(L/G)^(1/2), where L is the length of the pendulum and G is the gravitational force, approximately 9.8 m/s². For a pendulum of length 1 meter, substituting these values results in T being calculated as 2.01 seconds. The discussion highlights confusion regarding the role of length in the formula, clarifying that it is accounted for in the calculation but does not appear in the final simplified result. The value 2.01 seconds represents the period of a simple pendulum with a length of 1 meter under standard gravitational conditions. Understanding this formula is essential for accurately determining pendulum behavior.

1. Why is 2.01 the accepted value for a pendulum?



2. T = 2pi(L/G)^1/2
L is the length of the Pendulum
G is the Gravitational Force



3. This is what the teacher did but I'm not sure why it works this way:

T = 2pi(L/G)^1/2
T= (2pi/(G)^1/2) x (L)^1/2
T = 2pi/(9.8)^1/2
T = 2.01

What happened to the Length?

Thanks for your help! =)

That is for a pendulum of length 1m,
 
That's the period of a simple pendulum having a length of 1 m.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
