Answer:
c) 8.3 x 10^24 molecules
Explanation:
First of all, we convert the volume of the glass of water from mL to 
:
The relationship between mass and volume is:
where
is the density of water
M is the total mass of the glass of water
is the volume of the water in the glass
Solving for M,
Now we know that the mass of a single molecule of water is
The total mass of the water in the glass can be written as
where
N is the number of molecules in the glass of water
Solving for N, we find:
Answer:
Explanation:
Firstly, we have to define momentum.
Momentum is define as the product of mass and velocity.
That is P = mass×velocity
Also considering the third law of motion which states that: For every action, there is equal and opposite reaction.
Moreso, considering the 2nd law of motion which states that the rate of change in the momentum of a body is equal to the applied force and takes place in the direction of the applied force.
Now, applying P = mass×velocity
They both have same mass and velocity definitely, they will both experience same momentum.
Also from the question, the both share same velocity hence, the will both hit the wall with same velocity meaning the will both feel the same impact from the wall as well. Hence the third law of motion proves this right.
18.5164213 if you divide them both you get that number so the volceity is the number shown above.
