Draw the feynman diagrams for do โ k-+ ฯ+ and d0 โ k+ + ฯ. use cabbibo's theory to estimate the ratio of decay rates: in this case, where the q-values of the two decay modes are the same, the decay rates are proportional to the square of their matrix element.

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/mยทยฐc) with 1.5-mm-thick air space (k = 0.026 w/mยทยฐc) between the layers. assuming the inner surface temperature of the jacket to be 28ยฐc and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0ยฐc and the heat transfer coefficient at the outer surface is 25 w/m2ยทยฐc. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/mยทยฐc) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
