STATEMENT 1 When the unit for measurement of a quantity is changed, its numerical value changes STATEMENT 2 Smaller the unit of measurement matter is its numerical value
Units & Measurements - L2
A point P is 3units away from line L_1= 3x + 4y +5=0 and 4 units away from the line L_2 = 8x-by +9=0, The reflection of P on L_1, is P_1 the reflection of P_1 on L_2, is P_2 the reflection of P_3, on L_2, is P_4, Then the area (in sq. units) of figure formed by joining P_1P_2P_3, and P_4, is-
Units & Measurements - 3
Let L_1 = 0 and L_2 = 0 be two intersecting straight lines. Then the number of points, whose distance from L_1 is 2 units and from L_2 is 5 units is (i)1 (ii)0 (iii)4 (iv)infty
Let L_(1)=0and L_(2) =0 be two intarecting straight lines. Then the number of points, whose distacne from L_(1) is 2 units and from L_(2) 2 units is
Centrioles || Microscope || Unit OF measurement
The dimensional formula for a physical quantity x is [M^(-1)L^(3)T^(-2)] . The errors in measuring the quantities M ,L and T respectively are "1%" each.Then maximum percentage error that occurs in measuring the quantity 'x' is
