What is the difference between a direct and indirect interaction device Solution Indirect interaction device translate some action of the human body into data .Examples include a computer mouse or a joy stick. these devices have different physical attributes they share the cognitive commonality of mental translation between the human body and the machine. Direct interaction devices have no intermediary the movement of the body equals the input ti the machine .Example of Direct interaction device are touch screens and voice recognition system. Direct devices do not require conscious mental translation. the movement effort matches the display distance and performance .

What is the pH of a saturated solution of Zn(OH) 2 Ksp = 1.1*10 -21 ? Solution Zn(OH)2 (s) < ---> Zn+2 + 2 OH- let the molar solubility be s , then [Zn+2] = s [OH-] = 2s now Ksp = [Zn+2] [OH-]^2 Ksp = [s] [2s]^2 Ksp = 4s3 4s3 = 1.1 x 10-21 s = 6.5 x 10-8 now [OH-] = 2s = 2 x 6.5 x 10-8 = 1.3 x 10-7 now pOH = -log [OH-] pOH = -log (1.3 x 10-7) pOH = 6.886 now pH + pOH = 14 pH + 6.886 = 14 pH = 7.114 .

What is the pH of the buffer that results when 12.5 g sodium acetate (NaCH3CO2) is mixed with 503 mL of 0.435 M acetic acid (CH3CO2H) and diluted with water to 1.00 L? (Ka of CH3CO2H 1.8E-5) sodium acetate 82.03 g/mol acetic acid 6010 g/mol 5.20 4.90 4.74 4.59 1.59 Solution Moles of sodium acetate = weight / molecular mass Moles = 12.5 / 82.03 = 0.152 moles Molarity of sodium acetate = moles / volume of solution in litres Molarity = 0.152 / 0.503 = 0.302 moles / L CH3COOH = CH3COO - + H + Ka = [CH3COO - ] [H + ] / [ CH3COOH] 1.8 Ã— 10 -5 = [H + ] [0.302] / [0.435] [H + ] = 2.5 x 10 -5 = 0.000025 pH = -log [H+] pH = -log [0.000025] = 4.60 So the answer will be d (4.59) .

What is the final value of x after performing the following operations? (C++) int x = 21; double y = 6; double z = 14; y = x / z; x = 5.5 * y; Solution Answer: D.8 Explanation: in line 1, x value is 21 in line 2, y value is 6 in line 3, z value is 14; int lint 4, y = x /z will give 1.5 o y value become 1.5 at line 4 in line 5, x = 5.5 * y means x = 5.5 * 1.5 x = 8.25 But here x is int variable, so only numeric value will assign to x. so x value is 8. .

What is the difference between disk partitioning and formatting? Solution Disk partitioning is the act of dividing a hard disk drive (HDD) into multiple logical storage units referred to as partitions, to treat one physical disk drive as if it were multiple disks, so that a different file system can be used on each partition. formatting is the process of preparing a data storage device such as a harddisk drive, solid-state drive, floppy disk or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems. Partitioning creates logically grouped piece of memory and prepare disks for formatting. The operation allows to create logical disks. Meaning that you can have disks C, D and so on. Formatting using partitioned piece of disk to createaddress table for files to be stored. .

What is the difference in the TLS implementation that allows some exploits to work with one version but not another? Solution Yes in TLS implementation the benefits are vary from one version to another version. Here some of the differences between two versions of TLS. Comparsion of TLS 1.1 to 1.0 -------------------------------- * In TLS 1.0 we have Initialization vecor (IV). Now this is replaced with explicit IV to protect against Cipher block chaining attacks. * Using mac alert to handle padding errors, when decryption failed against Cipher block chaining attacks. *For protocol parmetres, IANA registries are defined. * Closing premature..so session cannot be resume. .

What is the difference between IS &IT? What is the difference between IS &IT? Solution Answer: IS and IT due to close relation between the both people confuse in both the terms. Information technology is subset of information science. Information science is an umbrella term for the systems . It bridges between computers and bussiness. Information science is heavily based on computer sciences and other technology based tools. It may include non technological systems as well. Information technology on the other hand is under the IS umbrella . It deals with the technology involved in information sciences. It is a srudy of design and implementation. .

What is the difference between interfaced system and integrated system in healthcare? Solution Interface acts like a bridge to shara information between the programs stll they came from two different vendors or they use two different programming constructs.An interface is having particular file format to move from among them Integration means it works as a whole to get the result.instead of of sharing the information between them. The usage of integration or interfaces for the health care system depends up on its usage and already existing software which is in the hands of different people in the health care system. The interfaces are to meet the work flow of the various groups of people where as integration is usefull for overall display of the health care system such look and feel is great in this perspective. And then flexibility is more .

what is the difference between a single beam spectrophotometer and a double beam spectrophotometer? Solution Only one major difference is there, remaining all are almost same. A single beam spectrophotometer uses a reference standard to standardize the instrument before note down the measurements. A double beam spectrophotometer splits the beam of light into two different paths, one of which passes through the sample while the other passes through a reference standard. Hope this helped you! Thank You So Much! Please Rate this answer as you wish.(\"Thumbs Up\") .

What is the difference between the formation of an ionic bond and formation of a covalent bond? What is the difference between the formation of an ionic bond and formation of a covalent bond? Solution Covalent bond: Covalent bonding is a form chemical bonding formed between two non-metals that have similar electro negativity es. For stabilization they share their electrons from outer molecule with others. Ex:Methane(CH4) Ionic bond: An ionic bond is formed between metal and a non metal.Non metal will have (-ve ion) stronger than metal having(+ve ion) and can get electrons easily from metal. These two opposite ions attract each other and for ionic bond Ex:Sodium chloride(NaCl) .

what is the difference an organic and inorganic molecule Solution Compounds which are isolated directly or indirectly from living organisms are called organic compounds. Urea, sugar, oils, fats, proteins, vitamins are some example of organic compounds. Compounds which are isolated from from non-living sources, such as rocks and minerals are called inorganic compounds. Common salt, marble, alum, zinc sulfate are some examples of inorganic compounds. Modern definition of organic compounds: Compounds of carbon containing usually hydrogen and one and more than other elements such as oxygen, nitrogen, sulfphur, halogens, etc are called organic compounds. .

What is the conjugate base of H2SO4? What is the conjugate base of H2SO4? Solution Conjugate base is what is left over after an acid has donated a proton during a chemical reaction. Hence, a conjugate base is a species formed by the removal of a proton from an acid. H 2 SO 4 sulfuric acid will donate an H + in solution to form H 3 O + hydronium. The remaining HSO 4 - would be the conjugate base of this dissociation. .
