To solve the problem, we need to suggest two corrective measures eachbow legsround shoulders, which are common postural deformities.
1. Corrective Measures for Bow Legs:
Bow legs (genu varum) is a condition where the legs curve outward at the knees while the feet and ankles stay together.
2. Corrective Measures for Round Shoulders:
Round shoulders is a postural issue where the shoulders slouch forward, often due to weak back muscles and tight chest muscles.
Final Answer:
Two corrective measures for bow legs are: (1) Butterfly Stretch, and (2) Use of orthotics or leg braces.
Two corrective measures for round shoulders are: (1) Wall Angels, and (2) Chest stretching exercises.
A current-carrying coil is placed in an external uniform magnetic field. The coil is free to turn in the magnetic field. What is the net force acting on the coil? Obtain the orientation of the coil in stable equilibrium. Show that in this orientation the flux of the total field (field produced by the loop + external field) through the coil is maximum.
Three students, Neha, Rani, and Sam go to a market to purchase stationery items. Neha buys 4 pens, 3 notepads, and 2 erasers and pays ₹ 60. Rani buys 2 pens, 4 notepads, and 6 erasers for ₹ 90. Sam pays ₹ 70 for 6 pens, 2 notepads, and 3 erasers.
Based upon the above information, answer the following questions:
(i) Form the equations required to solve the problem of finding the price of each item, and express it in the matrix form \( A \mathbf{X} = B \).
