Amass m=15.0 kg is pulled along a horizontal floor, with a coefficient of kinetic friction μk =0.06, for a distance d=8.5 m. then the mass is continued to be pulled up a frictionless incline that makes an angle θ=35.0° with the horizontal. the entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ=35.0° (thus on the incline it is parallel to the surface) and has a tension t=45.0 n.1) what is the work done by tension before the block gets to the incline? 2) what is the work done by friction as the block slides on the flat horizontal surface?

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
