While doing bicep curls, tamara applies 155 newtons of force to lift the dumbbell. her forearm is 0.366 meters long and
she begins the bicep curl with her elbow bent at a 15° angle below the horizontal, in the direction of the positive x-axis.
determine the magnitude of the torque about her elbow.
[got deleted from mathematics when it's for pre-calculus, if this isn't physics or math where should i ask my question? ]

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
