Answer:
East
Explanation:
Given Newton's third law of motion; "Action and reaction are equal and opposite", when a student jumps off a sled toward the west after it stops at the bottom of an icy hill, the sled will move in the East direction.
This is because, the force exerted on the sled is a reaction force and is opposite in direction to the force that thrusts the boy westward though equal in magnitude with the former.

Answer:
e. 81.0%
Explanation:
Morphine has Molar mass = 285.34 g/mol
Also, number of males of Morphine = Number of moles of HCl
(At equivalence point )
Now, number of moles of HCl = Molarity × volume
=0.01 mol × 2.84×10^(-3) L
= 2.84×10^(-5) mol
therefore number of moles of morphine= 2.85×10^(-5)
Mass of Morphine= No. of moles × molar mass
= 2.84×10^(-5)×285.34 g/mol
= 0.0081 g
= 8.1 mg
therefore
percentage of morphine = mass of morphine/ mass of powder×100%
= 8.1/10×100% = 81.0%
hence option e is correct.
