Families in transition are often dealing with difficult (and unexpected) circumstances. Consider your childhood or some of your friends’ early childhood histories. Are there any transitions that stand out as particularly stressful for you (or your friends)? Briefly describe the transition and what you think an educator could have done to help.

Rad Co. manufactures and sells heating and air conditioning systems. Rad Co is a public company.
On September 1, 2021 Rad sold 20 heating systems to Heating Rental Company for $50,000 (on credit). The cost of the heating systems sold was $1,000 each. Heating Rental Company is a new customer. Rad offers a 60-day return policy. Based on past experience usually 5% of the systems will be returned.
Prepare the journal entries for September 1st.

Co-planar test is an important step in continuous collision detection. Let p0= [0,0,0], p1= [1,0,1], p2= [0,1,1], p3= [1,1,0] be four points and v0= [0,0,0], v1= [1,0,0], v2= [0,1,0], v3= [0,1,1] be their velocities. Please derive the formula to compute the time when these four points are co-planar. (Hint: You may use Unity or calculator to compute dot and cross products. You don’t need to give the time solution.)

Be sure to answer all parts. The water-gas shift reaction plays a central role in the chemical methods for obtaining cleaner fuels from coal: CO(g) + H2O(g) ⇌ CO2(g) + H2(g) A study was made in which equilibrium was reached with [CO] = [H2O] = [H2] = 0.100 M and [CO2] = 0.400 M. After 1.40 mol of H2 is added to the 2.00−L container and equilibrium is reestablished, what are the new concentrations of all the components?

2. Use the following data (measured at 1200 K) to estimate the value of Kp at 1200 K for the reaction:
2H2(g) + O2(g) ↔ 2H2O(g)
Data:
C(graphite) + CO2(g) ↔ 2CO(g) Kc = 0.64
CO2(g) + H2(g) ↔ CO(g) + H2O(g) Kc = 1.4
C(graphite) + 1/2 O2(g) ↔ CO(g) Kc = 1.0 x 108

a) Define the following terms: (i) ferroelectric (ii) piezoelectric
b)Draw perspective and plan views of the unit cell of cubic barium titanate. Label the fractional co-ordinates of the non-equivalent ions and state the co-ordination number of the ions. [6 marks] (ii) Describe, with the aid of appropriate diagrams, the various structural changes which occur as a barium titanate crystal cools from 200°C to -100°C. Specify the temperatures of the relevant phase transitions.

1. Predict whether each of the following equilibria will shift toward products or reactants with a temperature increase:
a. CH4(g) + H2O(g) === CO(g) + 3H2( g) Delta H = +206kJ
b. CO(g) + H2O(g) CO2(g) + H2(g) Delta H = -41 kJ
c. 2SO2(g) + O2(g) = 2SO3(g) Delta H = -198 kJ
d. N2O4 (g) ===== 2NO2 (g) Delta H = + 57kJ

The Newton Co. is a new firm in a rapidly growing industry. The company is planning on increasing its annual dividend by 15% a year for the next four years (Year 1, Year 2, Year 3, and Year 4) and then increase at the constant growth rate of 5% per year indefinitely. The company just paid its annual dividend in the amount of $1.50 per share. What is the current value of Newton Co.’s stock if the required rate of return is 8%?
