along the snow. The force in the rope (tension) is 94.0N. How much work is done on the sled? Solution: W= Fd W= 94.0N x 35.0m W= 3290 Nm or J 2. The cable of a large crane applies a force of 2.2x10^4N to a demolition ball as it lifts it vertically a distance of 7.6m. a) How much work is done on the ball? b) Is the work positive or negative? Why? Solution: A.) W=( 2.2x10^4N) ( 7.6 m) W= 1.6x10^5 Nm or J B.) Positive‚ because the force

Lactated Ringer’s Solution Lactated Ringer’s classified as an isotonic or crystalloid solution‚ has similar osmolarity to body fluids‚ meaning that it maintains fluid volumes in balance between the space inside and outside the blood vessels. Lactated Ringer’s contains electrolytes‚ substances necessary for cells to function. It’s intended for intravenous administration‚ but if a suitable vein cannot be found it can be given orally which has an unpleasant taste. It is made up of NaCl (sodium chloride)
