परावैद्युत क्या है इधर भी उधर भी परावैद्युत के उदाहरण देकर समझाइए​

Answer»

लक पदार्थों को परावैद्युत (DIELECTRIC) कहते हैं जिनके अन्दर विद्युत क्षेत्र पैदा करने पर (या जिन्हें विद्युत क्षेत्र में रखने पर) वे ध्रुवित हो जाते हैं। कुचालक (इंसुलेटर) से आशय उन सभी पदार्थों से है जिनकी प्रतिरोधकता अधिक (या विद्युत चालकता कम) होती है किन्तु परावैद्युत पदार्थ वे हैं जो कुचालक होने के साथ-साथ पर्याप्त मात्रा में ध्रुवण का गुण भी प्रदर्शित करते हैं। किसी पदार्थ के ध्रुवण की मात्रा को उसके परावैद्युत स्थिरांक (dielectric CONSTANT) या परावैद्युतांक से मापा जाता है।

A particle is moving along a circular track of radius r. What is the distance traversed by particle in three fourth revolution?​

Answer» BRAINLIST Explanation:According to your question, the body moves from point A to point B thereby completing HALF a revolution. Since distance is the LENGTH of PATH covered therefore it will be equal to half the circumference i.e. 1/2 × 2pi r or pi × r. And the displacement is equal to the distance between initial and final point. Therefore it will be equal to the diameter or r+r=2r.please mark as brainlist

A tennis ball is thrown up and reaches a height of 4.05m before coming down. What was its initial velocity ?How much total time will it take to come down ?(Assume g=10m/s²)​

Answer»

ement (s) = 4.05 mg = -10 m/s² Final velocity (v) = 0 m/sTo find: Initial velocity (u) = ? Total (t) = ?Formulae: v² = u² + 2gs, u + gtTotal = 2 × tSolution: v² = u² + 2gs0² = u² + 2 × (-10) × 4.050 = u² - 81u² = 81u = 9 m/sv = u + gt0 = 9 + (-10) × t10 t = 9T = 0.9 sTime of ascent = TIME of descent ttotal = 2T= 2 × 0.9 = 1.8 sThe initial velocity was 9 m/s and total time taken to come down, is 1.8 s.

a peeble is thrown vertically upwards and rises to a height of 19.6m find the time taken by the ball to reach max height ​

Answer»

6 m. U = ? V = 0s = ut +1/2 gt^2 (let g = 10m/s)19.6 = ut + 5t^2 ---- 1V = u + gt0 = u + 10t --- 2Substituting VALUE of u in equation 2, we getu = -10tSubstituting value of u in equation 1, we get,19.6 = -10t^2 + 5t^2- 5t^2 = 19.6t^2 = - 3.92 (Squares cannot be negative. HENCE TAKE mod value)t = √3.92 = 1.97 seconds or 2 seconds. corrections in your question :-u is not given. the values cannot be negative.
