A 0.5750-kg ice cube at -12.40°C is placed inside a chamber of steam at 365.0°C. Later, you notice that the ice cube has completely melted into a puddle of water. If the chamber initially contained 6.430 moles of steam (water) molecules before the ice is added, compute the final temperature of the puddle once it settled to equilibrium. (Suppose the chamber walls are adequately flexible to allow the system to remain isobaric and consider thermal losses/gains from the chamber walls as negligible.)
An electron and a proton are each accelerated starting from rest through a potential difference of 30.0 million volts. Find the momentum (in MeV/c) and the kinetic energy (in MeV) of each, and compare with the results of using the classical formul..
Monochromatic light of wavelength 675 nm falls on a slit. If the angle among the first bright fringes on either side of the central maximum is 21.5°, estimate the slit width.
Two objects (39.0 and 23.0 kg) are connected by a massless string that passes over a massless, frictionless pulley, find the acceleration of the objects
Suppose now that you are at rest relative to the raft standing at the rear end except this time the raft is in the middle of the lake moving at a speed of 4.0 m/s. find the raft's speed relative to a stationary observer
What is the magnitude of the average force on Superman's chest from the stream of bullets.
Use conservation of energy to determine the angular speed of the spool shown in the figure below after the 3.00 kg bucket has fallen 4.50 m, starting from rest. The light string attached to the bucket is wrapped around the spool and does not slip as ..
You jog at 6.8 mi/h for 5.0 minute, then you jump into a van and drive for another 5.0 minute. Compute with what average speed must you drive
A person is standing on the edge of a disk of radius R rotating about its axis. the person walks to a postition of R/4. Is a coeficient of static friction of 0.7 enough to keep the person from slipping when they are at a position of r= R/4.
In Young's double slit interferance experiment, it is foundthat the second bright fringe is at the angle of 20 degrees. find the wavelength of the light source
