I believe I have correct answer, but I'd just like to confirm with others...
Question: What is the density of an object that is 14% submerged when floating in water at 0 degrees C?
density of water at 0 degrees C = 999.87, according to my book
So the formula I set up is...
((density...
Question: A block of mass .05 kg is pulled .3 m from its equilibrium position and released. The spring constant is 5 N/m
What is the total energy of the block-spring system?
My book says E = K + U or E = (1/2)mv^2 + (1/2)kx^2. My book also says E_total = (1/2)kA(amplitude)^2. Which formula...
Let me see if my conversions are correct first. I assumed the air outside is equal to 1 atm. soo
Pressure inside the bottle (Pbottle) = (4.5)(101,325) = 455962.5 Pa
Pressure outside the bottle (Pair) = (1)(101,325) = 101.325 Pa
If my conversion is wrong, please correct me
And, since I'm...
Here's my homework question...
The pressure inside a bottle of champagne is 4.5 atm higher than the air pressure outside. The neck of the bottle has an inner radius of 1.0 cm (.01 m). What is the frictional force on the cork due to the neck of the bottle that keeps the cork in the bottle...
