Force F = (-9.0 N) i + (5.0 N) j acts on a particle with position vector r = (-5.0 m) j + (1.0 m) k .
(a) What is the torque on the particle about the origin?
(b) What is the angle between the directions of r and F? (If there is no torque, enter 0.)
(c) What is the angle between the directions of force and torque? If there is no torque, enter 0.
A glass coffee pot has a circular bottom with a 9.00cm diamteter in contact with a heating element that keeps the coffee warm with a continous heat transfer rate of 50.0w, what is the temperature of the bottom of the pot, if it is 3.00mm thick and..
Two circular disks spaced 0.50 mm apart form a parallel-plate capacitor. Transferring 1.50 ×109electrons from one disk to the other causes the electric field strength to be 2.90 ×105N/C
