A dc shunt generator has a speed of 800 rpm when delivering 20 A at 220 V. If this machine is run as a motor and takes a line current of 20 A at 220 V supply, the speed will be:-1. 800 rpm2. more than 800 rpm3. less than 800 rpm4. zero |
|
Answer» Correct Answer - Option 1 : 800 rpm Concept: In a DC shunt generator, generated emf is given by Eg = Vt + IaRa In a DC shunt motor, back emf is given by Eb = Vt – IaRa Where Ia is armature current Ra is armature resistance N is speed E ∝ N Given: Speed of generator (Ng) = 800 rpm Terminal voltage (Vt) = 220 V Armature resistance (Ra) = 0 Ω Armature current (Ia) = 20 A Eg = V + IaRa = 220 + 20 (0) = 220 V Eb = V - IaRa = 220 - 20 (0) = 220 V \(\frac{E_g}{E_b}=\frac{N_g}{N_m}\) \(\frac{E_g}{E_m}=\frac{220}{220} = 1\) Em = Eg = 800 rpm |

For the admission in a college, weight 40 is given to the marks in 12th class and weight 60 is given to the marks in entrance exam of each student. As per the merit list of the college, a student can get admission only if his weighted marks are 77 %. If a student scored 82 % in 12th class and 78 % in the entrance exam, can he get the admission to this college ? |
|
Answer» Weight of marks in 12th is 40% and student gets 82% is 12th. ∴ Weightage of his 12th marks in college admission is 82/100 x 40 = 328/10 = 32.8 Weight of marks in entrance exam is 60% and student get 78% in the entrance exam. ∴ Weightage of his entrance exam marks in college admission is 78/100 x 60 = 468/10 = 46.8 Weightage marks of student in college admission is 32.8+46.8 = 79.6% > 77% Since, student's weightage marks is 79.6% which is greater than 77%. ∴ Student can get admission into the college. |

Write an essay of about 150 words by developing the following hints.Miss Meadows, a music teacher – gets a letter – feels upset – Fiance not interested – reflects her gloom on students – changes the happy song to a sad one – Headmistress calls – delivers a telegram – Fiance agrees to wedding – Meadows happy – changes the song again to a cheerful one. |
|
Answer» Miss Meadow was heart-broken. The letter written by Basil had pierced her heart and she was bleeding. Her hatred and anger became a knife and she carried it with her. Her icy cold response to Science Mistress demonstrates it. She is least bothered about the tender feelings of young children who look at her face all time for a friendly nod or smile of approval. Her favourite pupil Mary Beazley is baffled at her treatment of the chrysanthemum she had brought with so much love. The choice of the song “A lament” perfectly jells well with her worst mood. She is in fact in her heart lamenting over the loss of love, trust and future hopes. She is unnecessarily severe with young children forcing them to redo the singing which drives them to despair, pain and tears they manage to stifle. After she receives the telegram from Basil apologizing for his insane letter, her mood changes to joy. She takes the chrysanthemum and keeps it close to her lips to conceal her blush. She goads the children to sing a song of joy congratulating someone for success. She persuades them to show warmth in their voices. Her warm and lively voice dominates the tremulous voices of the young ones. The young ones now realize that Miss Meadow who was in a wax earlier is now in her elements. |

What are the rules and different stages of wedding? ( Bengal wedding)বিয়ের নিয়ম ও বিভিন্ন ধাপ কি কি? (বাংলার বিয়ে) |
|
Answer» The rules and different stages of Bengali wedding are:- 1. Bor Jatri Bor Jatri is basically the baarat, where the groom, his family and friends dress up for the wedding and start their journey to the bride’s house or the wedding venue. 2. Bor Boron This Bengali wedding ritual comes after the bor jatri or the baarat reaches the bride’s place. Normally, the bride’s mother along with other family members welcome the groom and his side of the family by doing aarti with the holy lamp and serving the sweets and drinks. 3. Potto Bastra In this Bengali marriage ritual, the groom is seated at the chadnatolla, or the wedding mandap, where he is offered new clothes by the person who is to do the sampradaan. This is usually done by an elderly male member of the bride’s family, most commonly the bride’s father or uncle. 4. Saat Paak Saat Paak is that Bengali wedding ritual where the bride sits on a low wooden stool called pidi. This stool is then lifted by her brothers and the bride is taken around the groom in seven circles. This ritual signifies that they are wound up to each other. 5. Subho Drishti After saat paak Bengali marriage ritual, the bride and the groom look at each other in front of guests. The bride removes the betel leaves from the front of her face and looks at the groom. This exchange of loving glance marks the beginning of the couple to be together in witness of their family and friends. 6. Mala Badal Sitting high on the pidi after the shubho drishiti, the bride and the groom exchange garlands of flowers three times. This Bengali wedding ritual marks as the first step of accepting each other as man and wife. 7. Sampradan Sampradan is basically the equivalent of Kanyadaan in a Hindu wedding ceremony. In the Bengali wedding ritual of Sampradan an elderly male member (almost always, her father) of the bride’s family gives her hand to the groom, when both their hands are tied by a sacred thread while reciting Vedic chants. 8. Yagna In this Bengali marriage ritual, the bride and groom sit in front of the yagna or the sacred fire and chant mantras after the priest. 9. Saptapadi In this Bengali wedding ritual, the couple takes seven rounds around the fire or the yagna, thereby solemnizing their marriage. 10. Anjali In this Bengali wedding ritual, an offering of puffed rice is made into the yagna by the bride and the groom. The bride’s brother gives puffed rice in the bride’s hands while the groom holds her hand to pour the offering into the yagna together. 11. Sindoor Daan In this last and final Bengali wedding ritual, the groom applies sindoor or vermilion to the bride’s hair-parting. Thereafter, the bride is considered as a married woman, since applying sindoor is one of the many solah shringas. |
