Answer:
The bowling ball with mass 8 pounds has greater acceleration.
Explanation:
The acceleration on the objects is equal to the quotient of the force applied on it and its mass. From Newton's second law of motion, we have;
F = ma
where F is the force on the object, m is its mass and a is its acceleration.
⇒ a =
Let us assume that a force of 50 N was applied on the two bowling balls.
Thus;
mass of the first bowling ball = 8 pounds = 3.62874 kg
So that,
50 = 3.62874 x a
a =
= 13.779
The acceleration of the first ball is 13.78 m/.
For the second ball of mass = 13 pounds = 5.8967 kg
So that,
50 = 5.8967 x a
a =
= 8.4793
The acceleration of the second ball is 8.48 m/.
Therefore, the bowling ball with mass 8 pounds has greater acceleration.

B. Kryptonite
C. Quartz
D. Pyrite
To solve this we use the equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the volume of the stock solution, M2 is the concentration of the new solution and V2 is its volume.
2.5 M x V1 = 0.50 M x .100 L
V1 = 0.02 L or 20 mL
Answer:
20 milliliters
Explanation:
I don't cap
THe pH of the solution containing NaF and HF would be higher than that of a solution of HF only.
The presence of NaF drives the reaction towards the HF side to reach equilibrium.
The concentration of H+ is higher in an HF solution containing NaF.
The pH of the solution containing NaF and HF would be lower than that of a solution of HF only.
The presence of the dissolved NaF does not affect the HF equilibrium reaction nor the equilibrium concentrations.
