A The drawing refers to one mole of a monatomic ideal gas and shows a process that has four steps, two isobaric (A to B, C to D) and two isochoric
How do you calculate the expected tension in the cord? Why can't you swing the ball so the cord remains exactly horizontal? How do you calculate the angle.
The mass of an elevator is 698 kg. The tension in the cable is 9250 N. At what rate does the elevator accelerate upward?
The masses of the blocks and how far out from the center they sit varies. The specific values are given in the figures.
During a hockey game, a puck is given an initial speed of 12.00 m/s. It slides 54.00 m on the ice before it stops.
Two particles of masses mi and m2 are attached to the ends of a light spring. The natural length of the spring is 1, and its tension is k times its extension
A hunter aim directly at a target (on the same level) 120 meters away. If the bullet leaves the gun at a speed of 250m/sec, by how much will it miss the target?
For an x,y origin at the point where it loses contact, find the x and y coordinates of the impact point on the ground.
A cylinder (cross section is 0.2m2) with a free moving piston is filled with gas. The piston is attached to a heavy weight W = 10000N.
Thermodynamics: Efficiency of a Carnot cycle
Develop a relationship between acceleration am, of the descending mass, and the linear acceleration ac, of the c. m. of the cylinder up the plane.
Using your research findings from the Library and the Internet, develop both an EFAS (External Factors Analysis Summary) table and an IFAS
If the speed is doubled, does the centripetal force double? If not, by what factor does the centripetal force increase?
One mole of an ideal gas is contained in a thermally insulated container that is connected to another container of equal volume that is initially evacuated
Two volumes V1 and V2 of the same incompressible liquid at temperatures T1 and T2 are mixed together in a thermally isolated container.
An insulated cylinder closed at one end by a frictionless piston contains 20g of hydrogen gas at 30 degrees Celsius.
A frictionless block in contact with a uniform cylinder, remains in contact as both accelerate down the plane. Block slides and cylinder rolls without slipping.
A toy model for DNA molecules. A DNA molecule is made of two complementary strands, which are hold together by hydrogen bonds.
Define the partition function Z for a system in terms of the energies E1 of its quantum states j and the inverse temperature /3 = (I T)''.
Diagram shows M at position x with spring force -kx acting to accelerate the mass toward the origin.
A balloon is descending with a constant acceleration "a" less than 'g' weight of the balloon with the basket and the contents is W.
On the 'x vs t' set of axes show qualitatively, the x(t) graph of each spacecraft. Include x and t coordinates of intersections and intercepts.
Show that the entrophy can be written as
He pulls down on a rope as shown, to raise himself and the cage. The man and cage have a total weight of 639 nt. Ignore friction as negligible.
A crate rests on a truck which is traveling at speed V= 26 m/sec down a hill inclined at angle b= 8 degrees.
