Calculate the torque needed to keep the ball rotating at constant angular velocity if air resistance exerts a force of 0.026 N on the ball. Ignore air resistance on the rod and its moment of inertia. Express your answer to two significant figures and include the appropriate units.

which expression represents the approximate length of bc?

step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
