A rectangular coil of wire with an area of 0.218 m2 is situated in a constant magnetic field whose magnitude is 0.450 T. Suppose the normal to the surface of the coil is parallel to the direction of the magnetic field (this means the magnetic field is also normal, or perpendicular, to the surface of the coil). What is the flux through the surface?
If the area of the coil is reduced to 0.150 m2 while keeping the orientation of the coil the same, what is the new flux through the surface?
Go back to a coil with an area of 0.218 m2, but instead rotate the coil such that the normal to the surface of the coil is perpendicular to the direction of the magnetic field (this means the magnetic field is parallel to the surface of the coil). What is the flux through the surface?
Find out (a) the coefficient of kinetic friction between m2 and the incline, (b) the acceleration of each mass, and (C) the tension in the string.
A 220 g block hangs from a spring with spring constant 12 N/m. At t=0;{rm s} the block is 31cm below the equilibrium point and moving upward with a speed of 89.0 cm/s. What is the block's distance from equilibrium while the speed is 30 cm/s.
In what direction should the plane head in order to fly.
A nanowire is a (nearly) one-dimensional structure with a diameter on the order of a few nanometers.
After the engine is ignited, what is the rocket's speed when the spring has stretched 19.00 cm past its natural length? What would be the rockets speed after travelling the distance if it weren't tied down to spring.
