I would say its the last answer
Answer:
Injections of aqueous solution of fruct
levulose of formula C, H, O,,
For
prevent dehydration such solutions are obtained
dissolving a mass m = 25g of fructose for a volume of 50
final solution.
1.1 Calculate the molecular molar mass of fructose
1.2 Determine the amount of corresponding fructose material
1.3 Calculate the molar concentration of these fructose solutions
1.4
Answer:
69.74 N
Explanation:
We are given that
Weight of sled=49 N
Coefficient of kinetic friction
Weight of person=585 N
Total weight==mg=49+585=634 N
We know that
Force needed to pull the sled across the snow at constant speed,F=Kinetic friction

Where N= Normal=mg

Hence, the force is needed to pull the sled across the snow at constant speed=69.74 N
Answer:
size get smaller maybe there is no object remaining
Answer: A while driving a car. It is unsafe
