The questions for this assignment are to be submitted through crowdmark i) for case (a) to (c) derive the merical formula for the energy using electron volts as a unit. do both cases for (c). also convert the boltzman constant to units of evk1. i want to have common units for the energies, while starting from the comonly used expressions this will get the point across that energies are very different ii) for cases (a) to (d), at room temperature (300k), calculate the ratio of finst excited pground ii) for cases (a) to (d), at room temperature (300k), calculate the lowest index r (representing n, , or v) of the excited state for whiclh ground such that its contribution starts to be negligible (or small at least). use the following equations to simplify this question: pground pground

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

Iwill give 30 points to whoever answers ! what is the formula for actual mechanical advantage and ideal mechanical advantage?
