Three pendulums with strings of the same length and bobs of the same mass are pulled out to angles θ1, θ2, and θ3, respectively, and released. the approximation sin θ = θ holds for all three angles, with θ3 > θ2 > θ1. how do the angular frequencies of the three pendulums compare?

The angular frequencies of all the 3 pendulums shall be same.

Explanation:

The time period of a simple pendulum with the approximation is given by:

The angular frequency is given by

As we can see that the angular frequency is independent on the initial angle (valid strictly for small angle approximations) we conclude that the angular frequencies of the 3 pendulums are the same.

prolly a beacuse the momentuem the car has increases while going down hill

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
