At what altitude is 0 gravity?

At what altitude is 0 gravity? Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·s−2 per 3,200 km.) Which force is always attractive in nature? gravitational force Why gravity is not […]

What is hydraulic principle?

What is hydraulic principle? The basic principle behind any hydraulic system is very simple – pressure applied anywhere to a body of fluid causes a force to be transmitted equally in all directions, with the force acting at right angles to any surface in contact with the fluid. This is known as Pascal’s Law. What […]

What does velocity relative to the ground mean?

What does velocity relative to the ground mean? The velocity of the object measured relative to the ground is called the ground speed. Again, this is a vector quantity. Airspeed is the vector difference between the ground speed and the wind speed. On a perfectly still day, the airspeed is equal to the ground speed. […]

Is nitrogen-14 an isotope?

Is nitrogen-14 an isotope? Nitrogen-14 is one of two stable (non-radioactive) isotopes of the chemical element nitrogen, which makes about 99.636% of natural nitrogen. Nitrogen-14 is one of the very few stable nuclides with both an odd number of protons and of neutrons (seven each) and is the only one to make up a majority […]
