Three moles of an ideal monatomic gas are at a temperature of 396 K. Then 2438 J of heat is added to the gas, and 897 J of work is done on it. What is the final temperature of the gas?
A container holds 1.3 mol of gas. The total average kinetic energy of the gas molecules in the container is equal to the kinetic energy of a 6.6x10-3 kg bullet with a speed of 670 m/s. What is the Kelvin temperature of the gas?
Imagine that you collected your data above, threw away the gel, and re-ran PCR again on the same samples, but using a different set of primers. How will the 2nd gel differ from the first since you're using a different set of primers?
(a) Transform the expression (x − a)^2 + y^2 = a^2 into polar coordinates. (b) Sketch the region R bounded by the curve given in part (a). (c) Use a double integral in polar coordinates to ﬁnd the area of the region R.
The drawing shows a 25.1-kg crate that is initially at rest. Note that the view is one looking down on the top of the crate. Two forces, 1 and 2, are applied to the crate, and it begins to move. The coefficient of kinetic friction between the crate and the floor is μk = 0...
15. To travel a fixed distance, the number of gallons needed is inversely proportional to the miles per gallon rating P of the car that gets 42 miles per gallon (mpg) needs 33 gallons to travel the distance. a. Find an equation of variation N= b. A car that gets 77 mpg needs _...
Two cars, A and B, are traveling in the same direction, although car A is 204 m behind car B. The speed of A is 22.9 m/s, and the speed of B is 18.6 m/s. How much time does it take for A to catch B?
A rifle that has been "sighted in" for a 94.6-meter target. If the muzzle speed of the bullet is v0 = 429 m/s, what are the two possible angles è1 and è2 between the rifle barrel and the horizontal such that the bullet will hit the target? One of these ...
