PLEASE HELP WITH C (I will mark brainliest) A skier starts from rest at the top of a frictionless incline of height 20.0 m, as shown. At the bottom of the incline, the skier encounters a horizontal surface where the coefficient of kinetic friction between skis and snow is 0.210.
a) Find the skier’s speed at point B. (ANS: 19.8 m/s)
b) How far does the skier travel on the horizontal surface before coming to rest? Neglect air resistance. (ANS: 95.2 m)
c) What would be the skier’s speed at B if the inclined plane is a frictional surface with the same coefficient of kinetic friction, 0.210 between the skis and the incline.

the word that best describes martin luther king jr.'s tone in the video is dignified

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

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.
