Answer 1

Answer:

चौथी चुनौती यह है कि अक्सर पार्टियां हमारे देश में मतदाताओं को सार्थक विकल्प प्रदान नहीं करती हैं आर्थिक नीतियों में सभी प्रमुख दलों के बीच अंतर कई बार एक पार्टी से दूसरे दल में स्थानांतरित होने वाले नेताओं के एक ही सेट को कम कर दिया है कि लोगों के पास उनके पास कोई विकल्प उपलब्ध नहीं है

Answer 2

Answer:

1 . The frequency of AC current in India is 50Hz. The frequency of this alternating current varies from one country to another. 2 . On 29 August 1831 Michael Faraday discovered the induction of one current by another in his famous induction ring experiment familiar to every student of Magnetic lines of force are defined as the curved lines which are used for representing the magnetic field. These lines do not exist but are imaginary lines through the pattern of the magnetic field is explained. These imaginary lines are assumed to originate from the north pole and reach to the south pole by travelling inside the magnet thereby completing the loop.sics 3.An electrical circuit in a device of lower resistance than that of a normal circuit, especially one resulting from the unintended contact of components and consequent accidental diversion of the current. 3.
