A horizontal force of 1000 N is needed to overcome the force of static friction between a level floor and a 250-kg crate. If g = 9.8 m/s2, what is the coefficient of static friction?
 a. 4.0
  c. 0.41
  b. 0.51
  d. 0.31

Question 2

A block of mass 5.00 kg rests on a horizontal surface where the coefficient of kinetic friction between the two is 0.200 . A string attached to the block is pulled horizontally, resulting in a 3.00 m/s2 acceleration by the block. Find the tension in the string. (g = 9.80 m/s2)
 a. 0.200 N
  c. 19.8 N
  b. 9.80 N
  d. 24.8 N

Stevens-Johnson syndrome and Toxic Epidermal Necrolysis syndrome are life-threatening reactions that can result in death. Complications include permanent blindness, dry-eye syndrome, lung damage, photophobia, asthma, chronic obstructive pulmonary disease, permanent loss of nail beds, scarring of mucous membranes, arthritis, and chronic fatigue syndrome. Many patients' pores scar shut, causing them to retain heat.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
