The standard acceleration due to gravity at the surface of the Earth is approximately 9.81 m/s².

The standard acceleration due to gravity on the surface of the Earth is approximately 9.81 m/s².

The slopes are m1 = 2 and m2 = -1/2. The angle θ = tan^(-1) |(m1 - m2) / (1 + m1*m2)| = tan^(-1)(5/4) which is approximately 60 degrees.

The angle for the first minimum is given by sin θ = λ/a, where a is the slit width. Thus, sin θ = 500 nm / 0.5 mm = 0.001, leading to θ ≈ 30°.

Arc length = (θ/360) * 2πr; 5 = (θ/360) * 2π * 10; θ = (5 * 360) / (20π) = 30 degrees.

Angular momentum L = mvr, where v is the tangential speed. L = 2 kg * 4 m/s * 3 m = 24 kg·m²/s.

The approximate value of gravitational acceleration on Earth is 9.8 m/s².

Circumference = 2πr; 31.4 = 2πr; r = 5 cm; Area = πr² = 25 cm².

Radius = diameter/2 = 10/2 = 5 cm. Area = πr² = π(5)² = 25π cm².

Radius = diameter/2 = 16/2 = 8 cm. Area = πr² = π(8)² = 64π cm².

Radius = diameter/2 = 16 cm / 2 = 8 cm. Area = πr² = 3.14 * 8² = 201.06 cm².

Area = πr² = π * 10² = 314 m².

Area = πr² = π * 3² = 28.26 cm².

Area = πr²; = π * 3² = 28.26 m².

Area = πr^2 = π(7^2) = 49π ≈ 154.

Area = length * width = (4-1) * (5-1) = 3 * 4 = 12.

Area of sector = (θ/360) * πr²; = (90/360) * π * 4² = 12.56 cm².

Area of sector = (θ/360) × πr²; = (90/360) × π(4)² = 2π cm².

Area of sector = (θ/360) * πr² = (90/360) * π * 7² = 38.5 cm².

Area = 1/2 * base * height = 1/2 * 10 * 5 = 25 cm².

Area = 0.5 * base * height = 0.5 * 1 * 1 = 0.5 square units.

Area of base = πr² = π(3²) = 9π square units.

Area of base = πr² = π(4)² = 16π square units.

The argument of -1 + 0i is π (180 degrees) since it lies on the negative x-axis.
