Calculate the ratio of the Einstein coefficients for spontaneous versus stimulated emission (A/B) for a rotational transition of I_2 from J = 5 Rightarrow 4. The equilibrium bond length of I_2 is 266.6 pm. ii) Without further calculation, do you expect the ratio of the coefficients to increase or decrease for the transition from J = 50 Rightarrow 49?

B) raising the temperature and reducing the volume of the gas.|-/ 

Velocity=total displacement/timefrom house to store is 500 from store to neighbor is 200 therefore total displacement=500+200=700metrestherefore,700metres/910seconds=0.8metres per second

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
