Answer 1

Answer:

सूखा रोग (रिकेट्स) हड्डियों का रोग है जो प्राय: बच्चों में होता है। बच्चों में हड्डियों की नरमाई या कमजोर होने को सूखा रोग कहते हैं। परिणामस्वरूप अस्थिविकार होकर पैरों का टेढ़ापन और मेरूदंड में असामान्य मोड आ जाते हैं।It ruined Loisels' lives because they had to buy a diamond necklace worth thirty-six thousand dollars to buy a new necklace for her friend. They were indebted as it was a huge amount. Thus, it made them poor and snatched all their hopes of a happy life. It took away ten prime years of their lives.

Answer 2

When a body is free to rotate around an axis, torque must be applied to change its angular momentum. The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body.
