Question

the ski camber allows the kick surface of the ski to contact the snow only when the ski is...
off of the binding
in the ski rack
weighted
strapped on a backpack
un - weighted
if you feel like you are about to fall on a pair of cross country skis, it is best to fall...
forward, using your hands to catch yourself.
onto your poles.
onto your side, putting your elbow out to catch your fall.
backwards onto your buttocks.

Explanation:

First Question (Ski Camber):

The ski camber's design means the kick surface contacts snow when the ski has weight (is weighted) to compress the camber, allowing contact. Other options like being off the binding, in a rack, strapped to a backpack, or un - weighted don't involve the functional use of the camber for snow contact.

In cross - country skiing, falling onto your side with the elbow out to catch the fall is the best practice. Falling forward (hands to catch) can lead to injury from the skis or terrain, falling onto poles can damage equipment or cause injury, and falling backward onto the buttocks is less stable and can lead to more impact on the back/buttocks.

Answer:

Weighted
