Newtonian Cosmology 1. In class, we solved the Friedmann equation for the critical case, where the constant of integration was set to k 0; this resulted in the Einstein-de Sitter model, where a ox t2/3 Now, let us consider the closed case (k 1), where the universe starts with a Big Bang, reaches a maximum expansion, turns around, and eventually ends in a Big Crunch. For the closed model, it is convenient to write the Friedmann equation as follows: 8T...
I did this normallt but I need to use laplace tranforms. The differential equation for a single closed RL-circuit is, by Kirchoffs Second Law, di where i() is the current in the circuit at time t, L is the inductance, R is the resistance, and E(t) is the impressed voltage. In this lab you will investigate the current under voltages that are nonzero for only a brief period of time. Assuming the values L R 1, solve the LR- circuit...
can you solve for me the exercises 2 in class I need all of these please thank you so much Exercise 10. Show that J dz converges. Class Exercise 2.

part B asap 3. The differential equation describing the current in a circuit is given by: dai(t) d+2° +2-06 + 5i(t) = v(t) dt a) Find i(t) fort > 0 using Laplace transforms if v(t) = 10u(t) and given that initial conditions are i(0+) = 4 and dico*) = -2. b) write an expression for i(t) if: 3 3 sin (2nnt - tan-1(4nt)) v(t) = nv1 + 16n2t2
suppose an input voltage is given as V(t) = 240[u(t-5) - u(t-10)]. In a branch of an electronic circuit, the variation of current with time is modeled by the differential equation d^2(i)/dt^2 + 36i = dv/dt. Assuming zero initial conditions, determine I as a function of t. (hint: use laplace transforms)
During the current year D sold a property in class 12 for $9,000. The property had an original cost of $12,000. At the beginning of the current year the UCC of class 12 was $5,000. No other class 12 transactions occurred during the year. What is the increase to D’s net income for tax purposes, if any, for the current year as a result of the sale?
