Question

स्पष्ट करो कि पृथ्वी का चुंबकावरण परिभ्रमण का परिणाम है।

​

Answer 1

Answer:

डायनामो इफेक्ट नावाच्या प्रभावामुळे पृथ्वीचे चुंबकीय क्षेत्र होते.

पृथ्वीवरील बाह्य गाभामध्ये द्रव धातूचे वाहणारे विद्युत प्रवाह कसे निर्माण होतात हे पाहता हे स्पष्ट केले जाऊ शकते.

पृथ्वीच्या अक्षावर फिरण्यामुळे या विद्युत प्रवाहांना एक चुंबकीय क्षेत्र तयार होते जे ग्रहभोवती पसरते, म्हणूनच चुंबकीय क्षेत्रे कशा तयार होतात हे दर्शविते.

पृथ्वीचे परिभ्रमण खरंच चुंबकीय क्षेत्र तयार करते.

Answer 2

Rays parallel to principal axis of a convex lens get converge at a distance 6cm from the lens at what distance from the lens a concave mirror of focal length 3cm must be placed so that after reflection from the mirror and refraction in opposite direction from the lens rays will again become parallel to principal axis.
