A reaction vessel contains 8.06 g of H2 and 64.0 gof O2 at a temperature of 125?C and a pressure of 125kPa .
What is the volume of the vessel?
The hydrogen and oxygen are now ignited by a spark, initiating the reaction 2H2+O2?2H2O.
This reaction consumes all the hydrogen and oxygen in the vessel. What is the pressure of the resulting water vapor when it returns to its initial temperature of 125?C?
A man of mass 65 kg falls stiff-legged straight down from a height of 2m. He lands on one foot. The femur is a bone in the leg with the length L=.65m, and a cross-sectional area of about 2.0 x 10^-4m^2. The Young's modulus for bone is 9.4x 10^9 N/..
The charge experiences a magnetic force of 7.41 10-3 N. A second charge q2 = 4.00 µC travels at an angle of 40.0° with respect to the same magnetic field and experiences a 1.80 10-3-N force. Identify the magnitude of the magnetic field and the ..
