Answer» Answer: EXPLANATION:Not all coalescers provide a high quantitative removal of dispersed liquid contaminants and can handle emulsions with low interfacial tensions (IFTs). For example, conventional cartridge coalescers made of glass fiber media begin to lose EFFICIENCY when the IFT of the emulsion gets below 20 dyne/cm. Introducing Pall AquaSep® Series Liquid/Liquid Coalescers The new AquaSep Series coalescers utilize a high-efficiency, polymeric medium, making it well SUITED for numerous liquid/liquid separation applications with very low IFTs. DOWNLOAD the guide to learn how AquaSep coalescers can help improve your process. Advantages • 60% more FLOW than before • Continuous service applications • As low as 15ppmv free water • Coarse grade for dirty flows • Great CAPEX • Low OPEX |

Calculate the number of images formed by two plane mirrors placed at an angle of 30 degree to each other.State any two applications of multiple reflection. |
|
Answer» Answer: If the image of an object is VIEWED in two plane mirrors that are inclined to each other more than ONE image is formed. The NUMBER of images depends on the angle between the two mirrors. The number of images formed in two plane mirrors inclined at an angle A to each other is given by the below formula.Number of images n= 360/A - 1 The number of images formed n=(360/A)-1, if (360/A) is even integer.If (360/A) is odd integer, the number of images formed n=(360/A)-1 when the object is kept symmetrically, and n=(360/A) when object is kept ASYMMETRICALLY. If (360/A) is a fraction, the number of images formed is equal to its integral part. As the angle gets smaller (down to 0 degrees when the mirrors are facing each other and parallel) the smaller the angle the greater the number of images. Here, the angle A between the mirrors is 40 degrees. Case (a): The object is symmetrically placed. The number of images formed = (360/40)-1, we get 8 images. Case (b): The object is asymmetrically placed. The number of images formed = (360/40), we get 9 images. Hence, the number of images formed are 8 and 9 respectively. |

The angles of a qadrilateral are in the ratio 2:3:4:6.FIND in the measure of each of THE four angles |
|
Answer» Answer: Given RATIO of ANGLES :-2:3:4:6 Let each angle of the quadrilateral be 2x,3x,4x and 6x. Sum of all the angles of a quadrilateral =360 ∘
∴2x+3x+4x+6x=360 ∘
⇒15x=360 ∘
⇒x= 15 360
⇒x=24 ∘
∴ required angles are 2×24 ∘ ,3×24 ∘ ,4×24 ∘ ,6×24 ∘ =48 ∘ ,72 ∘ ,96 ∘ ,144 ∘ |

The hissing sound that you hear while opening a bottle of Coke is the result of gas which was previously dissolved in the Coke, escaping from solution and "whizzing" through the small opening in the Coke bottle you have created by opening the top. The hissing noise is the same hissing noise you hear when you deflate a bike tire, or let helium out of a tank; it is the sound of rushing gas. But an important question is : Which one of the following gases rush out of the Coke bottle ? *1 point*Oxygen*Hydrogen*Nitrogen*Carbon dioxide |

CHECKING YOUR UNDERSTANDINGACTIVITY 1. My ChangesDirection: What are the common changes happening to an adolescent/s?PhysicalMentalSocialChange/sChangelsChangelsEmotionalChangels |
|
Answer» Answer: Social changes in adolescence Identity Young people are busy working out who they are and where they fit in the world. You might notice your CHILD trying out new things like clothing styles, music, art or friendship groups. Friends, family, media, culture and more shape your child’s choices in these years. Independence Your child will PROBABLY want more independence about things like how he gets to places, how he spends his time, who he spends time with, and what he spends money on. As your child becomes more independent, it’ll probably mean some changes in your family routines and relationships, as well as your child’s friendships. Responsibility Your child might be KEEN to take on more responsibility both at home and at school. This could include things like cooking dinner once a week or being on the school council. New experiences Your child is likely to look for new experiences, including risky experiences. This is normal as your child explores her own limits and abilities, as well as the boundaries you set. She also needs to express herself as an individual. But because of how TEENAGE brains develop, your child might sometimes struggle with thinking through consequences and risks before he tries something new. Values This is the time your child starts to develop a stronger individual set of values and morals. She’ll question more things, and she’s also learning that she’s responsible for her own actions, decisions and consequences. Your words and actions help shape your child’s sense of ‘right’ and ‘wrong’. Influences Your child’s friends and peers might influence your child, particularly his behaviour, appearance, INTERESTS, sense of self and self-esteem. You still have a big influence on long-term things like your child’s career choices, values and morals. Sexual identity Your child might start to have romantic relationships or go on ‘dates’. But these aren’t always intimate relationships. For some young people, intimate or sexual relationships don’t occur until later on in life. Media The internet, mobile phones and social media can influence how your child communicates with friends and learns about the world. Emotional changes in adolescence Moods and feelings Your child might show strong feelings and intense emotions, and her moods might seem unpredictable. These emotional ups and downs can lead to increased conflict. They happen partly because your child’s brain is still learning how to control and express emotions in a grown-up way. Sensitivity to others As your child gets older, he’ll get better at reading and understanding other people’s emotions. But while your child is developing these skills, he can sometimes misread facial expressions or body language. Self-consciousness Teenage self-esteem is often affected by appearance – or by how teenagers think they look. As your child develops, she might feel self-conscious about her physical appearance. She might also compare her body with those of friends and peers. |

|
Answer» Answer: Explanation: Kinetic energy=1/2mv² Let the kinetic energy of body traveling with UNIFORM VELOCITY be (K.E)1 And the kinetic energy of the body traveling with uniform velocity 2V be (K.E)2 So the REQUIRED ratio of their kinetic energy be =(K.E)1/(K.E)2 =[1/2mv²]\[1/2m(2v)²] =v^2/4v² =1/4 So,the ratio kinetic energy of the both bodies are 1:4. |
