5.9 × 10^24 = 5,900,000,000,000,000,000,000,000 minus 13,000,000,000,000,000,000,000 equals 5,887,000,000,000,000,000,000,000 kg which is the amount greater that Earth's mass is. you could write this problem as 5.9 × 10^24 - 13 × 10^21 = 5.887 × 10^21
Step-by-step explanation: (a) Vector BA = position vector of B - position vector of A = vector OB - vector OA = (3-6) i + (4-2) j = -3i+2j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-3,2). (b) Vector BC = position vector of B - position vector of C = vector OB - vector OC = (3-12) i + (4-(-2)) j = -9i+6j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-9,6).
