An object of height 19.7 cm is placed 23.6 cm from a convex lens. What is the angular size of this object?
A violet ray of light leaves a first medium at an angle of 0.79 radians to the normal and enters a second medium at 0 56 radians to the normal. Given that the refractive index of the second medium is 1.33. What is the refractive index of the first medium?
Make a program that will accept an arithmetic operators (either +,-,*,/ and %) and two numbers to compute. It has to display the correct answer based on the operator you enter.
Noted: Since there are 5 arithmetic operators to choose from, there should be cases followed by the default.
1) At a particular temperature k= 6.7x10^-6 for the following reaction:
2Br2(g) +O2(g) -> 2Br2O(g)
In an experiment in which 1.0 mol of Br2 and 1.0 mol of O2 are mixed in a 2.5-L vessel, what are the equilibrium concentrations of all gases?
2) At a particular temperature k= 6.5x10^-6 for the following reaction:
2Cl2(g)+O2(g) -> 2Cl2O(g)
In an experiment in which 2.0 mol of Cl2 and 1.5 mol of O2 are mixed in a 2.0-L vessel, what are the equilibrium concentrations of all gases?
