In this scenario, what is the test statistic? The claim is the percent of U.S. adults who owe more than $8000 on their credit cards is less than 38%. Sample size =46 U.S. adults Sample proportion =0.28

Calculate the energies velocities for H2 (mass 2.000 amu) and O2 (mass 32.00 amu) molecules in 3 dimensions and 2 dimensions. (The only difference between motion in 2 dimensions rather than 3 dimensions is that you replace 3RT by 2RT.) Calculate for H2 and O2 at both 100 kelvin and 1000 kelvin. Also calculate the average kinetic energies in kJ/mol

A vertical straight wire 25.0 cm in length carries a current. You do not know either the magnitude of the current or whether the current is moving upward or downward. If there is a uniform horizontal magnetic field of 0.0350 T that points due north, the wire experiences a horizontal magnetic force to the west of 0.0140 N. Find (a) the magnitude and (b) the direction of the current.
