Answer:
The answer to the very last one is: Boyle's law. Pressure and volume are inversely proportional as the new variable changes from the known. Pressure doubled equals 1/2 of original volume, assuming temperature remains the same. So 40.0 mL is the new volume as it is compressed.
Answer: Spaceships
Explanation: The spaceships defy physics. Your Welcome. :)
Answer:
- Here we use the conservation of momentum theorem.
- m stands for mass, and v stands for velocity. The numbers refer to the respective objects.
- m1v1 + m2v2 = m1vf1 + m2vf2
- Since the equation is perfectly inelastic, the final velocity of both masses is the same. Let’s account for this in our formula.
- m1v1 + m2v2 = vf(m1 + m2)
<u>Let’s substitute in our givens.</u>
(0.002 kg)(700 m/s) + (5 kg)(0 m/s) = vf(0.002 kg + 5 kg)
I assume you are proficient in algebra I, so I will not include the steps to simplify this equation.
Note that I have considered the bullet’s velocity to be in the positive direction,
The answer is vf = 0.280 m/s
Because they both have to do with chemistry
