Scurvy is caused due to deficiency of:
To solve the problem, we need to identify the cause of scurvy, specifically which nutrient deficiency leads to this condition.
1. Understanding Scurvy:
Scurvy is a disease historically associated with sailors and others deprived of fresh fruits and vegetables for extended periods. It is characterized by symptoms such as bleeding gums, poor wound healing, and fatigue.
2. Identifying the Deficiency:
Scurvy is caused by a deficiency of Vitamin C (ascorbic acid), a water-soluble vitamin essential for collagen synthesis, antioxidant functions, and connective tissue health. Lack of Vitamin C disrupts these processes, leading to the symptoms of scurvy.
3. Considering Other Possibilities:
Other vitamin deficiencies cause distinct diseases (e.g., Vitamin D deficiency causes rickets, Vitamin B1 deficiency causes beriberi). No other nutrient deficiency is associated with scurvy, confirming Vitamin C as the correct answer.
Final Answer:
Scurvy is caused due to the deficiency of Vitamin C.
A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
