Calculate the net torque about the axle of the wheel, which starts its motion from rest. assume that a friction torque of 0.25 m⋅n opposes the motion. assume f1 = 27 n , f2 = 43 n , f3 = 25 n . express your answer to two significant figures and include the appropriate units.

How will the system respond to a temperature increase?

What determines the amount of inertia an object has

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
