Need a picture.
I imagine it as a wave enters a pool it's smaller as there is less waves. If it was a river,beach ,etc. Then it would be bigger as there is more space.
Answer:
A) How much work does the Pepsi do on the bullet = 0.0625J
B) At what velocity does the Pepsi hit the floor = 7.67m/s
Explanation:
- Given mass of bullet = 5g
- initial velocity = 500 m/sec
From work done = Force X Distance
Workdone ; m(v - u )/t
A) The work done by the Pepsi is equal to the change in kinetic energy while in the Pepsi:
- but The work done by the container wall on the bullet is equal to the change in kinetic energy on either side of the wall: W = change in kinetic energy = 1/2 mv²
= 1/2 X 0.005 x 500² - 1/2 X 0.055 x 5²
= 624.94J
- Therefore ; The work done by the Pepsi is equal to the change in kinetic energy while in the Pepsi = W = change in KE = 0.0625 - 0 = 0.0625J
B) At what velocity does the Pepsi hit the floor?
- From conservation of energy principle; PE = KE
Answer:
All your answers are correct except the last one I'm pretty sure.
Explanation:
For number 4. The answer I'm pretty sure is:
C. A chunky solid formed from two liquids.
A precipitate is formed when two liquids are mixed together and a chemical reaction takes place. For example curdling milk. When vinegar is added to milk, it causes the milk to curdle and form a precipitate.
