Access the answers of NCERT Solutions for Class 11 Physics Chapter 9 Mechanical Properties of Solids. Q1. A steel wire of length 4.7 m and cross-sectional area 3.0 × 10-5 m2 stretches by the same amount as a copper wire of length 3.5 m and cross-sectional area of 4.0 × 10-5 m2 under a given load. What is the ratio of Young's modulus of
V-Cube 6 in original packaging. The V-Cube 6 is a 6×6×6 version of the original Rubik's Cube.The first mass-produced 6×6×6 was invented by Panagiotis Verdes and is produced by the Greek company Verdes Innovations SA. Other such puzzles have since been introduced by a number of Chinese companies, most of which have mechanisms which improve on the original.
If (a 1 /a 2) = (b 1 /b 2) = (c 1 /c 2 ), then there will be infinitely many solutions. This type of equation is called a dependent pair of linear equations in two variables. If we plot the graph of this equation, the lines will coincide. Case 2. If (a 1 /a 2) = (b 1 /b 2) ≠ (c 1 /c 2 ), then there will be no solution.
3 - 3 = 0. 0 x 6 = 0. 0 + 2 = 2. If your calculator behaves in this simple way, you would need to apply the rules yourself. Here are the buttons to press: 3 x 6 = MS. 3 - MR + 2 =. If your calculator has brackets or parentheses buttons you can use them instead of the Memory buttons to achieve the same effect. 3 - ( 3 x 6 ) + 2.
The number obtained as a result of multiplication is called the Product. For Example, in 3 ⨯ 2 = 6, the product is 6. We can interpret product 6 as 6 being twice of 3 or two times of 3. If Multiplier and Multiplicand are interchanged then the product remains the same i.e. 3 ⨯ 2 = 6 and 2 ⨯ 3 = 6. Let's learn some properties of
We can compute a corresponding (complex) eigenvector in exactly the same way as before: by row reducing the matrix A − λIn. Now, however, we have to do arithmetic with complex numbers. Example 5.5.1: A 2 × 2 matrix. Find the complex eigenvalues and eigenvectors of the matrix. A = (1 − 1 1 1). Solution.
CBSE Class 6 Social Science Solutions Geography Chapter 4 Long Answer Type Questions. 1. Define and discuss 'distance' as a component of a map. [V. Imp.] Answer: Maps are drawings. They reduce the whole world or a part of it to fit on a sheet of paper. In other words we can say that maps are drawn to reduced scales.
