Answer:
D) 19.8 lbs
Explanation:
1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.
1kg is also equal to 2.205 lbs. 9*2.205=19.8416
9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system
a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.
This leaves us with 19.8 lbs
Here mass is floating on the piston at equilibrium
So it will have constant pressure always remains constant
So final pressure is same as initial pressure = 900 kPa
now we can say



so final pressure is 900 kPa and final volume is 1.14 m^3
Answer:
A 0.17 kg baseball is launched from the roof of a building 14 m above the ground. Its initial velocity is 29 m/s at 40° above the horizontal. Assume any effects of air resistance are negligible.

m
(b) What is the speed of the ball as it strikes the ground?
m/s
