The rate of change of B is twice that of A, so:
rate of change of B = 2 x -0.1
rate of change of B = -0.2 M/s
Answer:
D. gravity, friction, and an applied force.
Explanation:
There are 4 forces that act on an airplane in motion and they are:
Gravity and drag:
It acts in a downward direction—toward the center of the Earth.
Lift:
It is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.
Thrust:
It is the force that propels a flying machine in the direction of motion.

Answer: The molarity of a solution made by dissolving 12.6 grams of NaNO3 to make 200 ml of solution is 0.74 M
Explanation:
Molarity is defined as the number of moles of solute dissolved perliter of the solution.
where,
n= moles of solute
= volume of solution in ml = 1000 ml
Now put all the given values in the formula of molarity, we get
Thus the molarity of a solution made by dissolving 12.6 grams of NaNO3 to make 200 ml of solution is 0.74 M
