Electric Fields 1) The two objects shown are both positively charged. Which position could possibly have zero electric field? – A – B – C – D – They could all have zero electric field 2) What were the two most important forces that Milikan worked with in the oil-drop experiment? – frictional, electrical […]
Find the mean lifetime and decay constant for 57Co. If the activity of a 57Co radiation source is now 2.00 mCi, how many 57Co nuclei does the source contain? What will be the activity after one year?
Physics Question 1. The force constant for the internuclear force in a hydrogen molecule 1H22 is kΚΉ = 576 N/m. A hydrogen atom has mass 1.67 x 10-27 kg. Calculate the zero-point vibrational energy for H2 (that is, the vibrational energy the molecule has in the n = 0 ground vibrational level). How does this […]

Using your value for the most probable speed at 298 K for oxygen determined in part 3, determine the fraction of molecules at 298 K and at 500 K which have speeds greater than this speed.
The Kinetic Theory of Gases A Maple ExerciseThe kinetic theory of gases is one of the cornerstones of physical chemistry. It provides a model that allows the calculation of many dynamic properties of a perfect gas. Knowledge of molecular speeds and their distribution functions is useful in understanding the rates of gas phase reactions. TheoryThe […]
