The following decays do not occur in the standard model. state why they do not occur, giving all reasons in each case. also give the flavour content for the hadrons in the reactions. (ii) n> vevu (iii) p- nat (iv) p- rt πο

Aphysical change is a change in the size, shape,, or stafe of matter true or false

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

Give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.
