  2. Asked: January 11, 2020In: Class 9

    10 गाम की एक गोली 10की घात 3 मी/सेकेण्ड के वेग से बालू के बोरे से टकराती है और 20 सेमी अन्दर धँस जाती है ज्ञात कीजिए (1) गोली पर लगने वाला पतिरोधात्मक अचर बल (2) गोली के इसथर होने मे लगा समय

    दिया है: m = 10 g = 0.01 kg u = 1000 m/s v = 0 m/s s = 20 m गति के द्वितीय समीकरण v^2 = u^2 + 2as से 0 = (1000)^2 + 2 x a x 20 0 = 1000000 + 40 a इसलिए a = 1000000/40 = 25000 m/s^2 गोली पर लगने वाला प्रतिरोधक बल F = ma = 0.01 x 25000 = 250 N गति के पहले समीकरण से v = u + at 0 = 1000 + 25000 t इसलिएRead more

    दिया है:
    m = 10 g = 0.01 kg
    u = 1000 m/s
    v = 0 m/s
    s = 20 m
    गति के द्वितीय समीकरण v^2 = u^2 + 2as से
    0 = (1000)^2 + 2 x a x 20
    0 = 1000000 + 40 a
    इसलिए
    a = 1000000/40 = 25000 m/s^2

    गोली पर लगने वाला प्रतिरोधक बल
    F = ma = 0.01 x 25000 = 250 N

    गति के पहले समीकरण से
    v = u + at
    0 = 1000 + 25000 t

    इसलिए
    t = -1000/25000 = – 1/25 = -0.04 सेकेण्ड

  3. Asked: January 11, 2020In: Class 9

    तत्व का परमाणु क्रमांक 18 तथा द्रव्यमान संख्या 40 है। इसकी परमाणु संरचना का चित्र बनाइए ।

    Amit Sharma
    Added an answer on January 15, 2020 at 11:03 am

    इसका परमाणु क्रमांक 18 है, इसलिए K L M 2 8 8 इसकी परमाणु संरचना बनाने के लिए पहले शेल में 2 इलेक्ट्रान, दूसरे शेल में 8 इलेक्ट्रान और तीसरे शेल में भी 8 इलेक्ट्रान बनाएं .

    इसका परमाणु क्रमांक 18 है, इसलिए

    K L M
    2 8 8

    इसकी परमाणु संरचना बनाने के लिए पहले शेल में 2 इलेक्ट्रान, दूसरे शेल में 8 इलेक्ट्रान और तीसरे शेल में भी 8 इलेक्ट्रान बनाएं .
