Astudent and the waxed skis he is wearing
have a combined weight of 850 newtons. the skier
travels down a snow-covered hill and then glides
to the east across a snow-covered, horizontal
surface.
53 determine the magnitude of the normal force
exerted by the snow on the skis as the skier
glides across the horizontal surface.

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
