For a 2-dimensional (2 eigenvalues / 2 outcomes) problem, the statistical operator can be written as a nice form (20) 1. using the above expression, show that trp 1 which is the standard property of both pure and mixed statistical operators. 2. if |81 1, show that it represents a pure statistical operator.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the answer is mosques. they are an important part of islamic culture.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
