30 gms of a salt saturates 75gms of water at 250C. What is the solubility of the salt and the mass/mass percent of the given solution respectively? |
|
Answer» WEIGHT of salt = 90 gram, solubility = 50 sing formula solubility of solute = ×100 or 50= ×100 so weight of solvent in saturated SOLUTION = 50 90gm ×100=180gm Hence 180 gm of WATER is required to prepare a saturated solution. |

Logic circuit X for OR gate given logic circuit for both inputs A and BIs equivalent.X logic gate is (1) ஒரு NAND கேட் (3) ஒரு AND கேட் (2) ஒரு NOR கேட் (4) ஒரு OR கேட் |
|
Answer» Explanation: In the previous tutorials, we saw that by using the three principal gates, the AND Gate, the OR Gate and the NOT Gate, we can build many other types of logic gate functions, such as a NAND Gate and a NOR Gate or any other type of digital logic function we can imagine. But there are two other types of digital logic gates which although they are not a basic gate in their own right as they are constructed by combining together other logic gates, their output Boolean function is IMPORTANT enough to be considered as complete logic gates. These two “hybrid” logic gates are called the Exclusive-OR (Ex-OR) Gate and its complement the Exclusive-NOR (Ex-NOR) Gate. Previously, we saw that for a 2-input OR gate, if A = “1”, OR B = “1”, OR BOTH A + B = “1” then the output from the digital gate must also be at a logic level “1” and because of this, this type of logic gate is known as an Inclusive-OR function. The logic gate gets its name from the fact that it includes the case of Q = “1” when both A and B = “1”. If however, an logic output “1” is obtained when ONLY A = “1” or when ONLY B = “1” but NOT both together at the same time, giving the BINARY inputs of “01” or “10”, then the output will be “1”. This type of gate is known as an Exclusive-OR function or more COMMONLY an Ex-Or function for short. This is because its boolean expression excludes the “OR BOTH” case of Q = “1” when both A and B = “1”. In other words the output of an Exclusive-OR gate ONLY goes “HIGH” when its two input terminals are at “DIFFERENT” logic levels with respect to each other. An odd number of logic “1’s” on its inputs gives a logic “1” at the output. These two inputs can be at logic level “1” or at logic level “0” giving us the Boolean expression of: Q = (A ⊕ B) = A.B + A.B The Exclusive-OR Gate function, or Ex-ORfor short, is achieved by combining standard logic gates together to form more complex gate functions that are used extensively in building arithmetic logic circuits, computational logic comparators and error detection circuits. The two-input “Exclusive-OR” gate is basically a modulo two adder, since it gives the SUM of two binary numbers and as a result are more complex in design than other basic types of logic gate. The TRUTH table, logic symbol and implementation of a 2-input Exclusive-ORgate is shown below. |

If a force of 50N is applied to the bodyon the right side while a force of 20N is applied tothe body on the left side and initially body is at rest.What is the behaviour of the motion of the body? |
|
Answer» Explanation: Retarding force, F=50N Mass of the body, m=20kg Initial velocity of the body, u=15m/s Final velocity of the body, v=0 Using NEWTONS second LAW of motion, the acceleration (a) PRODUCED is given by: F=ma 50=20 ×a a=−50/20=−2.5m/s 2
Using the FIRST equation of motion, the time (t) taken by the body to come at rest v=u+at t=−u/a=−15/−2.5=6s |

Why do aeroplanes have the above-mentioned shape?Give two examples of similar body shapes. |
|
Answer» Answer: The shape of an airplane's wings is what makes it possible for the airplane to FLY. Airplanes' wings are curved on TOP and FLATTER on the bottom. That shape makes air flow over the top FASTER than under the bottom. As a RESULT, less air pressure is on top of the wing. |

21.A ball at 30°C falls in water at10°C, final temperature of eachwill be * a. 10 degree celsius b. 20 degree celsius c. 40 degree celsius |

Answer» Given : T m=130^oC h=6200 m S=126 Jkg −1C−1
LET the mass of the LEAD ball be m and its LATENT heat of FUSION be L. Initial temperature of the lead ball T1=30 ^oC The potential ENERGY of the ball gets converted into heat that melts the ball. ∴ mgh=mS(Tm−T1)+mL OR m(10)(6200)=m(126)(130−30)+mL OR 62000=12600+L ⟹L=4.94×10 4Jkg −1 |
