The escape velocity of the Earth is 11.2 km/sec. Escape velocity is the minimum speed an object needs to escape the gravitational pull of a celestial body. For Earth, this velocity is approximately 11.2 km/sec, enabling objects to overcome Earth’s ...
Pascal is the unit of pressure. Named after the French mathematician and physicist Blaise Pascal, it measures force applied perpendicular to an object’s surface per unit area. Pascal is commonly used in various fields, including physics, engineering, and meteorology, to ...
1 kg/cm² pressure is equivalent to 10.0 bar. Bar is a unit of pressure equal to 100,000 pascals, and 1 kg/cm² is equivalent to 10,000 pascals. Therefore, 1 kg/cm² pressure is equal to 10.0 bar.
Cusec measures the flow of water. It quantifies the volume of water passing a specific point in a watercourse per unit of time. Cusec, short for cubic feet per second, is commonly used in hydrology, agriculture, engineering, and environmental monitoring ...
