The figure shows the orientation of a rectangular loop consisting of 66 closely wrapped turns each carrying a current I. The magnetic field in the region is (40 i) mT. The loop can turn about the y axis. If θ = 30°, a = 0.3 m,

b = 0.5 m, and I = {i] A, what is the magnitude of the torque exerted on the loop?

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
