Which of the following buffer systems would be the best choice to create a buffer with pH = 9.05?HF}/KFHNO2/KNO2NH3/NH4ClHClO/KClO~for this I got NH3/NH4Cl because this would give off a buffer greater then (pH> 7.0).but I am having trouble with the second part:For the best system, calculate the ratio of the masses of the buffer components […]
4. A painter of mass 70.0 kg stands on a platform of mass 75.0 kg and pulls on two ropes which hang over pulleys. He pulls each rope with a force of 750.0 N. Assuming a coordinate system where +y is up, calculate the y-component of the acceleration ay. ay can either be positive or […]

1. A 1000kg convertible on the way to Pikes Peak stops on a 14.1% incline. Calculate the friction force between the tires and the road and the minimum coefficient of friction necessary to keep the car from sliding down the hill.(20) 2. A 5000kg truck is being pulled up a 15 degree ramp by a […]
The ratio of circumference to diameter for all circles is pi. What is the ratio of force to mass for freely falling bodies? Why doesn’t a heavy object accelerate more than a light object when both are freely falling?
Which of the following provides O2 as an end product?carbon fixationlight-independent reactionslight-dependent reactionsG3P productionphotorespiration
SLAC, the Stanford Linear Accelerator Center, located at Stanford University in Palo Alto, California, accelerated electrons through a vacuum tube two miles long. Electrons which were initially at rest were subjected to a continuous force of 2×10−12 newton along the entire length of two miles (one mile is 1.6 kilometers) and reached speeds very near […]
Calculate the moment of inertia of the array of point objects shown in the figure about the vertical axis. Assume m = 2.5kg , M = 3.3kg , and the objects are wired together by very light, rigid pieces of wire. The array is rectangular and is split through the middle by the horizontal axis. […]
