if additional ice had melted after the final temperature had been recorded, but before the water was poured out of the calorimeter would the calculated value of the heat of fusion have been higher lower or unchanged if additional ice had melted after the final temperature had been recorded, but before the water was poured out of the calorimeter would the calculated value of the heat of fusion have been higher lower or unchanged Solution Heat of fusion = (Q Heat lost by hot water - Q Heat gained by ice ) / mass of ice remaining Heat of fusion is inversely proportional to remaining mass of ice Now, if additional ice had melted after the final temperature had been recorded, then mass of ice would be less than recorded and heat of fusion calculated will be more than recorded after calculation .

If the Android platform you are developing for does not support fragments, how would you go about providing fragment-like processing in you Android Application ? Hints: Would you have multiply activities? Which UI elements (controls/widgets) would you use? Solution A Fragment represents a behavior or a portion of user interface in an Activity.. One big reason to stick with the SupportFragment for a while is that you do not have access to the ChildFragmentManager until API17. Instead of creating fragments we can use by custom views for mutliple display. Letâ€™s implementation of fragments in views. First, weâ€™ll have the notion of a Container, which can show an item and also handle back presses. The activity assumes thereâ€™s always a container and merely delegates the work to it. The list is also quite trivial. Now, the meat of the work: loading different XML layouts based on resource qualifiers. Using custom views works great, but we would like to isolate business logic into dedicated controllers. we call those parameters. This makes the code much more readable and facilitates testing. MyDetailView could look something like this Make your fragments shells of themselves. Pull view code up into custom view classes, and push business logic down into a presenter that knows how to interact with the custom views. Then, your fragment is nearly empty, just inflating custom views that connect themselves with presenters: At that point you can eliminate the fragment .

E 4. Elijah Samuels and Tony Winslow agreed to form a partnership. Samuels contributed $200,000 in cash, and Winslow contributed assets with a fair market value of $400,000. The partnership, in its initial year, reported net income of $120,000. Calculate the distribution of the first year\'s income to the partners under each of the following conditions: 1. Samuels and Winslow failed to include stated ratios in the partnership agreement. 2. Samuels and Winslow agreed to share income and losses in a 3:2 ratio. 3. Samuels and Winslow agreed to share income and losses in the ratio of their original investments. 4. Samuels and Winslow agreed to share income and losses by allowing 10 percent interest on original investments and sharing any remainder equally. Solution 1. When there is no stated ratio then profit distributed equally Share of Samuels = 120000x1/2= 60000 Share of winslow= 120000x1/2 = 60000 2. Share of Samuels=Â Â 120000x 3/5 = 72000 Share of winslow= 120000x2/5 = 48000 3. Value of investments= Samuels (200000) + Winslow (400000)= 600000 Share of samuels = 120000x200000/600000 = 40000 Share of winslow = 120000x 400000/600000= 80000 4. Income after interest on investments = 120000- 600000x10%= 60000 Share of samuels = 60000x1/2 = 30000 Share of winslow = 60000x1/2 =30000 .

During a total lunar eclipse, in which the moon passes entirely into the shadow of the earth as cast by the sun, the moon is not completely dark, but is often a deep red in color. The shade of red varies widely from one total eclipse to the other. Why? 1. During the sunset, the Sun transfers some red light to the moon. 2. The earth acts like a giant water drop because of its oceans, and the moon winds up 3. None of the worldâ€™s sacred holy books discuss this situation, so it must be forever a total mystery. 4. Low frequencies pass more easily through the long grazing path through the Earthâ€™s atmosphere to be refracted finally onto the moon. 5. High frequencies pass more easily through the long grazing path through the Earthâ€™s atmosphere to be refracted finally onto the moon. Solution 4) Some light from the sun passes through Earth\'s atmosphere and is bent toward the moon. Low frequencies (red is having low frequency and highest wavelength) pass more easily through the long grazing path through the Earthâ€™s atmosphere to be refracted finally onto the moon. .

During 2012, there were no transactions involving common stock, and the company reported net income of $4,032,000. 1. Determine the weighted-average number of common shares outstanding each year. 2. Compute earnings per shre for each year. Solution Answer : 1. weighted-average number of common shares outstanding each year. Note : = (3/4 * 2,800,000) +(1/4 *1,680,000) = 2,100,000 + 420,000 = 2,520,000 In year 2012 new shares are not purchased hence (Opening balance * 1) = 4,480,000 2. earnings per shre for each year Note : earnings per share = Net Income / Weighted Average No of outstanding shares .

Driving School has 4 learning centres. The network of each learning centre is a LAN of its own. Network Cheap is contracted to install network connections between the learning centres. Network Cheap proposed to use RIP version 2. As the CEO of Driving School, will you accept this proposal? If you do not accept the proposal, what would you use for the routing protocol? Give your reasons. Solution IGRPâ€”Interior Gateway Routing Protocol , EIGRPâ€”Enhanced Interior Gateway Routing Protocol or OSPF V2â€”Open Shortest Path First came to a mind but RIP V2â€”Routing Information Protocol is a good choice The characteristics of RIPv2 follow: Distance-vector protocol. Uses UDP port 520. Classless protocol (support for CIDR). Supports VLSMs. Metric is router hop count. Maximum hop count is 15; infinite (unreachable) routes have a metric of 16. Periodic route updates sent every 30 seconds to multicast address 224.0.0.9. 25 routes per RIP message (24 if you use authentication). Supports authentication. Implements split horizon with poison reverse. Implements triggered updates. Subnet mask included in route entry. Administrative distance for RIPv2 is 120. Used in small, flat networks or at the edge of larger networks. IGRP Converges slowly infact slower than RIP and for IGRP , OSPF or EIGRP all routers must be from Cisco Systems ( big constraint) .

DQ #4 Explain the US Government Thrift Savings Plans. Solution The US Government Thrift Savings Plans is a defined-contribution plan designed to give federal employees the same retirement savings related benefits which will be equal to that of workers in the private sector enjoy with 401(k) plans.
