60°, 120° and 180° are the angles at which it will map onto itself.
I honestly have no clue i just need to answer a question do i can ask my question that i needed help with,
Answer:
x<-2 ^;;:%%^^^::"%%^::::%^&&;::%^^^;::^^^&;;:%^_
You see how many times 4 can go into 25 witch is 6 not 7 because 7 x 4 is28 and 28is bigger than25 so the answer is and 1/4 is25 cence so the answer is 4.25
The mass of the pendulum does not affect the period and frequency
The period can be determined using the formula:
T = 2π √(L/g)
where L is the length of the rope
and g is the acceleration due to gravity = 9.8 m/s2
Plugging in the values:
T = 2π √(5/9.8)
T = 10π/7 = 4.49 s
And for the frequency:
f = 1/T
f = 1/4.49
f = 0.22 Hz
