At a mail sorting facility, packages slide down a ramp but are stopped part way down the ramp so that they can be scanned. while the packages are scanned, they are held in place by a horizontal force from a spring-loaded arm. calculate the minimum force that must be applied by this arm to hold a package on the ramp. the ramp is at an angle of 33.5° with the horizontal. the package has a mass of 9.25 kg. the coefficient of static friction between the ramp and the package is 0.455.

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
