The trap-jaw ant can snap its mandibles shut in as little as 1.3 10-4 s. in order to shut, both mandibles rotate through a 90° angle. what is the average angular velocity of one of the mandibles of the trap-jaw ant when the mandibles snap shut in 2.20 10-4 s?

Answer

given,

Time,t = 1.3 x 10⁻⁴ s

angle of rotation = 90° =

Average angular velocity of the mandible

        ω = 1.21 x 10⁴ rad/s

average angular velocity is equal to 1.21 x 10⁴ rad/s

if the time given is = 2.20 x 10⁻⁴ s

        ω = 7.14 x 10³ rad/s

average angular velocity is equal to 7.14 x 10³ rad/s

reserve is the answer

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
