In the figure below, we must apply a force of magnitude 60 N to hold the block stationary at x = -2.0 cm. From that position we then slowly move the block so that our force does +4.6 J of work on the spring-block system; the block is then again stationary. What is the block’s position (x)? (There are two answers.)
In the following figure, a metal wire of mass m = 20.3 mg can slide with negligible friction on two horizontal parallel rails separated by distance d = 2.56 cm.
The track lies in a vertical uniform magnetic field of magnitude 56.3 mT. At time t=0, device G is connected to the rails, producing a constant current i = 91.3 mA in the wire and rails (even as the wire moves). At t = 61.1 ms, what is the wire’s speed?
(Specify your answer up to two decimal places)
In the figure below, two blocks, of mass m1 = 350 g and m2 = 710 g, are connected by a massless cord that is wrapped around a uniform disk of mass M = 500 g and radius R = 12.0 cm. The disk can rotate without friction about a fixed horizontal axis through its center; the cord cannot slip on the disk. The system is released from rest.

in the first year of operations, Kelley company produced 10000 units and sold 7000 units. its unit costs were as follows: direct materials 12$, direct labour 8$ , variable manufacturing overhead 2$ , variable selling and administrative expenses 1$. Its total fixed manufacturing overhead for the year was 50,000$.
1- What is the amount of cost of goods sold under variable costing
a- 220,000$
b-161,000$
c-154,000$
d-230,000$
2-what is the amount of cost of goods sold under absorption costing
a-189,000$
b-196,000$
c-179,000$
d-186,000$
3-When comparing Kelley’s absorption costing net operating income to its variable costing net operation income, which of the following will be true .
a- Its absorption costing net operating income will be 35,000$ lower than its variable costing net operating income.
b- Its absorption costing net operating income will be 35,000$ higher than its variable costing net operating income.
c- its absorption costing net operating income will be 15,000$ lower than its variable costing net operating income.
d- its absorption costing net operating income will be 15,000$ higher than its variable costing net operating income.
4- Ferguson products Inc, a manufacturer , reported 130$ million in sales and a loss of 25$ million in its absorption costing income statement provided to shareholders. According to a CVP analysis prepared for management , the company’s break-even point is 120$ million in sales.
Assuming that the CVP analysis is correct , is it likely that the company’s inventory level increased , decreased, or remained unchanged during the year and explain
Hi Could someone please check my calculations for the question below:
2. In the first step of silicon purification, a reaction is brought about between the impure silicon and chlorine. Pure silicon is then used, in the computer industry, for the manufacture of microchips.
Si + Cl2 = SiCl4 (unbalanced equation)
Si + 2Cl2 = SiCl2
1 mol 2 mol 1 mol
Given that the silicon is 92% pure, calculate the theoretical yield percentage if 1.0 t of impure silicon produces 2.33 t of silicon (IV) chloride. (6 marks)
Molar Mass of SiCl4 = (28.9 +4 x 35.45) = 169.90 g/mol
Molar Mass of Si = (28.09) g/mol
Moles of SiCl4 = 1.0 x 10^6 g
169.90 g/mol
= 0.005885 x 10^6 mol or 5.885 x 10^3 mol
Number of moles of Si = 5.885 x 10^3 mol x1 = 5.885 x 10^3mol
1
Mass of Si = 5.885 x 10^3 mol x 28.09 g/mol = 165.309 x 10^3 g
= 1.65309 x 10^5 g
Yield% for Si = 2.3 x 10^6 g / 1.65309 x 10^5 g
= 3.80210 x 10^1 x 100 / 92 or 4%
