What is the frequency of motion of a 0.50 m long pendulum?
0.32 Hz
0.70 Hz
1.4 Hz
0.81 Hz
im not sure on this one
Period = 2 pi sqrt(l/g) = 2 pi sqrt (.5/9.81) = 1.419 sec
Frequency = 1/period = 1/1.419 = .70 hz
EP's answer is correct....
See this, Jenny : https://www.answers.com/Q/What_is_the_frequency_of_a_pendulum
hmm, im not quite sure then but i as well thought it was 0.70 hz
what about this one?
A 1.0 kg weight suspended from a spring is pulled to 0.25 m below its equilibrium point.
If the spring has a spring constant (k) of 50.0 N/m , at what rate will the mass accelerate when it is released?
200 m/s2
12.5 m/s2
6.5 m/s2
2.7 m/s2
2.7 ?
