What is the correct order of events for muscle contraction?
Your
A) Nerve impulse is sent; Calcium channels open; Tropomyosin moves to expose binding sites on actin; Actin and myosin form linkages; Thin filaments are pulled toward center
B) Nerve impulse is sent; Tropomyosin moves to expose binding sites on actin; Calcium channels open; Actin and myosin form linkages; Thin filaments are pulled toward center
C) Nerve impulse is sent; Actin and myosin form linkages; Calcium channels open; Tropomyosin moves to expose binding sites on actin; Thin filaments are pulled toward center
D) Nerve impulse is sent; Calcium channels open; Actin and myosin form linkages; Tropomyosin moves to expose binding sites on actin; Thin filaments are pulled toward center

Atank has a shape of a cone with a radius at the top of 2 m and a height of 5 m. the tank also has a 1 m spout at the top of the tank. the tank is filled with water up to a height of 2 m. find the work needed to pump all the water out the top of the spout. (use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
