How old is the oldest living thing on earth?
How old is the oldest living thing on earth? 5,000 years old What animal on earth lives the longest? Ming, a quahog clam, died at the age of 507 when researchers tried to dredge the bivalve up from Icelandic waters. The quahog’s life-span is usually about 225 years.

What is Lambda fuel ratio?
What is Lambda fuel ratio? Lambda represents the ratio of the amount of oxygen actually present in a combustion chamber compared to the amount that should have been present in order to obtain “perfect” combustion. Thus a lean air/fuel ratio of, say, 16:1 would translate to a lambda value of 1.088. (To calculate, divide 16 […]

What is the process of an electromagnet?
What is the process of an electromagnet? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. […]

Can the resultant of 3 vectors be zero?
Can the resultant of 3 vectors be zero? Answer. Three vectors are coplanar which means all three vectors are in the same plane. If direction of resultant of those two vectors is exactly opposite to the direction of the third vector. If all above conditions are satisfied, then the resultant of three vectors will be […]
