11. The mathematical model for the period of a pendulum found in a physics textbook is Z
T = 2
I
& It can be also written as T=4n?l/g. Input the T value you obtain from the .56 m
long pendulum you made and solve for g. How does this value compare to the accepted
value of 9.81 m/s?

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
