A solid, horizontal cylinder of mass 11.6 kg and radius 1.00 m rotates with an angular speed of 8.00 rad/s about a fixed vertical axis through its center. A 0.250-kg piece of putty is dropped vertically onto the cylinder at a point 0.900 m from the center of rotation and sticks to the cylinder. Determine the final angular speed of the system.
The freezing-point depression measurement of benzoic acid in acetone yields a molar mass of 122 g; the same measurement in benzene gives a value of 242 g
At what temperature would the rms speed of H2molecule be same?
The specific heat of water is 4.184 J/gxC. Assume the density of th water is 1.00g/mL and there is no heat lost or gained by the calorimeter.
85.0 mL of H2O is initially at room temperature (22. 0C). A chilled steel rod at 2.0 C is placed in the water. If the final temperature of the system is 21. 0C
Amounts of tin may be alloyed with copper to produce bronzes of varying composition and properties.
A 113L sample of helium at 27 degrees Celsius is cooled at a constant pressure to -78 degrees Celsius. calculate the new volume of the helium.
What are the mechanisms that prevent acid- base imbalances from appearing in the body, and where each mechanism functions most significantly?
What type of placarded hazardous material rail cars are not allowed to be next to rail car with temperature-controlled equipment?
How does theoretical yield allow you to determine the stoichiometry of the reaction?CaCl2.2H2O + K2C2O4.H2O ---> CaC2O4.H2O + 2KCl + 2H2O
