Using the formula for dew point approximation, Dew Point ≈ T - ((100 - RH) / 5) = 25 - ((100 - 60) / 5) = 25 - 8 = 20°C.

According to Ohm's Law, if the resistance is doubled while the voltage remains constant, the current will be halved.

Using Ohm's Law (I = V/R), I = 20 V / 10 Ω = 2 A.

According to Ohm's Law (I = V/R), if the resistance (R) is doubled while the voltage (V) remains constant, the current (I) will be halved.

Increased sediment load generally decreases the velocity of the river due to increased friction.

Vertical drop = Distance × Slope = 2000 m × (1/1000) = 2 m.

Soil eroded = 2 tons/hectare/year × 50 hectares × 5 years = 500 tons.

Soil eroded = Erosion rate × Area × Time = 2 tons/hectare/year × 50 hectares × 5 years = 500 tons.

Clay has lower drainage capacity compared to sandy soil.

Volume of water = Porosity × Volume of soil = 0.3 × 100 m³ = 30 m³.

Weight of water = Moisture content × Dry weight = 0.25 × 200 kg = 50 kg.

Weight of water = Moisture content x Weight of dry soil = 0.25 x 200 kg = 50 kg.

Water holding capacity = Soil moisture content × Volume of soil = 0.30 × 1000 liters = 300 liters.

Minimum votes required = (500/2) + 1 = 251.

Simple majority = (545/2) + 1 = 273.

A simple majority requires more than half, so (545/2) + 1 = 274 votes are needed.

Time = distance/speed = 1000 m / 340 m/s ≈ 2.94 s.

In an equilateral triangle, each angle is equal, so each angle = 180/3 = 60 degrees.

Let the other number be x. Then, x + 20 = 50, so x = 50 - 20 = 30.

Height = Shadow length * tan(angle) = 10 m * tan(30°) = 10 m * (1/√3) ≈ 5 m.

Using the lapse rate of 6.5°C/km, the temperature drop at 3000 meters is 6.5 * 3 = 19.5°C. Therefore, the temperature at 3000 meters is 30°C - 19.5°C = 10.5°C, which rounds to approximately 15.5°C.

Using the lapse rate of 6.5°C/km, the temperature drop at 1000 meters is 6.5°C. Therefore, 30°C - 6.5°C = 23.5°C, which rounds to 24.5°C.

Using the lapse rate of 6.5°C/km, the temperature drop at 3000 meters is 6.5 * 3 = 19.5°C. Therefore, the temperature at 3000 meters is 30°C - 19.5°C = 10.5°C.

According to Charles's Law, volume is directly proportional to temperature at constant pressure. A 10°C increase will result in a 10% increase in volume.

The saturation vapor pressure increases by approximately 6.5 hPa for every 1°C increase in temperature.

Expenditure on salaries = 30% of 100 crores = 0.3 * 100 = 30 crores.

20% of 545 = 0.20 * 545 = 109. Therefore, the closest option is 110.

20% of 545 = 0.20 * 545 = 109 women.

Percentage of Scheduled Castes = (84/545) * 100 = 15.4%

Percentage of women members = (78/545) * 100 = 14.3%
