Answer:
the new volume =93,750 Liters
Explanation:
From Boyles law
P1V1 = P2V2
1.2 X 125000 = 1.6 X V2
V2 = 93,750 Liters
Answer:
The Velocity at which it travels, and the Distance from start to finish.
Explanation:
Calculate V*D=T which is Velocity*Distance=Time.
Answer:
7kgm/s
Explanation:
Using the law of conservation of momentum which states that the sum of momentum of bodies before collision is equal to the sum of the bodies after collision.
Let P1A and P1B be the initial momentum of the bodies A and B respectively
Let P2A and P2B be the final momentum of the bodies A and B respectively after collision.
Based on the law:
P1A+P2A = P1B + P2B
Given P1A = 5kgm/s
P2A = 0kgm/s(ball B at rest before collision)
P2A = -2.0kgm/s (negative because it moves in the negative x direction)
P2B = ?
Substituting the values in the equation gives;
5+0 = -2+P2B
5+2 = P2B
P2B = 7kgm/s
Using current technology, useful parallax measurements can only be found for stars up to about 340 light years (100 parsecs) away.
