One afternoon, a couple walks three-fourths of the way around a circular lake, the radius of which is 1.47 km. They start at the west side of the lake and head due south to begin with. (a) What is the distance they travel? (b) What is the magnitude of the couples displac...
A hot-air balloon is rising upward with a constant speed of 2.22 m/s. When the balloon is 7.74 m above the ground, the balloonist accidentally drops a compass over the side of the balloon. How much time elapses before the compass hits the ground?
A police car is traveling at a velocity of 15.0 m/s due north, when a car zooms by at a constant velocity of 45.0 m/s due north. After a reaction time 0.700 s the policeman begins to pursue the speeder with an acceleration of 3.00 m/s^2. Including the reaction time, how long ...

a sample of hydrogen occupies a volume of 950 mL at -15.3 degrees celcius. if the temperature increased to 30.0 degrees celcius, what would be the new volume?
a sample of carbon dioxide has a volume of 25.0L at 5.80 x 10^2 mmHg. what pressure would be needed to increase the volume to 55.5 L? assume constant temperature
If a 0.10 M solution of silver fluoride, AgF, is mixed with a 0.10 M solution of barium acetate, Ba(C2H3O2)2, a pecipitate (ppt.) forms: AgF + Ba(C2H3O2)2--> ppt. In order to identify the precipitating ions, you conduct some experimental tests. a) what is the purpose of thi...
assume you had a solution that contained a mixture of a silver ions and stronium ions. come up with three different reaction plans that would allow you to precipitat either the silver ion or strontium ion, but the other ion would remain in solution
nevermind, figured it out!
