1A force of 200 N acts on an area of 4 m². The pressure is

2A train accelerates at 0.5 m/s² from rest. The time to reach 25 m/s is

3A U-tube contains water and oil. A 10 cm column of oil balances 8 cm of water. The density of oil is (water 1,000 kg/m³)

4The pressure at a depth of 10 m in water (ρ = 1,000 kg/m³, g = 10 m/s²) due to the water is

6A car moving at 72 km/h brakes uniformly to rest in 5 s. The stopping distance is

7Atmospheric pressure is measured with a

8In a hydraulic press, a 50 N force on a 0.01 m² piston lifts a load on a 0.5 m² piston of

9A hydraulic press works because pressure applied to an enclosed liquid

10A mercury barometer reads 76 cm. The atmospheric pressure is (ρ = 13,600 kg/m³, g = 10 m/s²)
