उत्तर : 3. "Inertia"
व्याख्या :
Answer: C) Inertia Explanation: To rotate is to energy to stop is to inertia. From the definition itself we know that inertia is a property by virtue of which a body continues to be in the state of rest or in state of motion. So over here whenever energy is supplied then the body starts to move that is a displacement is there and it is rotating where as whenever the body is stopped an inertia of rest is created. So, Rotate : Energy :: Stop : Inertia.

उत्तर : 4. "100000 ohm"
व्याख्या :
Answer: D) 100000 ohm Explanation: Under dry conditions, the resistance offered by the human body may be as high as 100,000(10^5) Ohms. Depending on the person, a rough value for the internal resistance of the human body is 300-1,000 Ohms. The skin's resistance is much lower if it is wet or burnt/blistered. There are a lot of factors involved and not every person has the same electrical resistance. For instance, men tend to have lower resistance than women. Within the body, the tissues with the greatest resistance are bone and fat - nerves and muscle have the least resistance.

उत्तर : 2. "60 yrs"
व्याख्या :
Answer: B) 60 yrs Explanation: Let the Father be x years when he died Average Age 10 years ago be A Total Age 10 years ago = 6*A Total Age after 10 years(Just before father's Death) = 6A + 6*10 = 6A + 60 Father Died and Baby was born => the Total number of people in the family is Same (6) Baby born today so age of baby = 0 (6A +60 - x)/6 = 6A/6 => A + 10 -(x/6) = A => x/6 = 10 => x = 60 Therefore we can conclude that the father was 60 years old when he died.
