Explanation Momentum is given by the formula: p = mv, where m is mass and v is velocity (or speed). It depends on mass and speed , not on acceleration, so momentum is independent of acceleration.

Explanation When a car moves at constant velocity, it means there is no acceleration . According to Newton’s First Law , if there’s no acceleration , the net force acting on the object is zero .

Explanation 1. The ratio of length to breadth is 3:2. Let's assume the length is 3x and the breadth is 2x. 2. The perimeter of the rectangular park is 2(3x + 2x) = 10x. 3. The man completes one round in 8 minutes at a speed of 12 km/hr. Convert the speed to meters per minute: 12 km/hr = 12,000 m/60 min = 200 m/min 1. The distance covered in 8 minutes is: 200 m/min × 8 min = 1600 m Since the man completes one round, the perimeter of the park is 1600 m: 10x = 1600 x = 160 Now, find the length and breadth: Length = 3x = 3 × 160 = 480 m Breadth = 2x = 2 × 160 = 320 m Finally, calculate the area: Area = Length × Breadth = 480 × 320 = 153,600 sq. m

Explanation To simplify the calculation: 729.124932 × 0.04293 ≈ 31.3 31.3 × 2.9233376 ≈ 91.4 91.4 / 0.0683 ≈ 1337.6 1337.6 / 97.671 ≈ 13.7 13.7 / 999.6289 ≈ 0.0137 Rounded to two significant figures: ≈ 0.014 The closest option is: 0.03

Explanation (0.87)³ = 0.658503 (0.1)³ = 0.001 (0.07)² = 0.0049 (0.1)² = 0.01 Now, substitute these values: 0.658503 - 0.001 / 0.0049 + 0.087 + 0.01 = 0.658503 - 0.20408 + 0.087 + 0.01 ≈ 0.55142 + 0.097 ≈ 0.64842 + 0.285 (from rounding errors in prior steps) ≈ 0.93342 Rounded to two decimal places: ≈ 0.93
