You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.

Q: The mahi-mahi (/ˈmɑːhiːˈmɑːhiː/) or common dolphinfish (Coryphaena hippurus) is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. Also widely called dorado and dolphin, it is one of two members of the Coryphaenidae family, the other being the pompano dolphinfish.

A: is mahi-mahi a type of dolphin?

Q: For nearly all models of induction cooktops, a cooking vessel must be made of, or contain, a ferromagnetic metal such as cast iron or some stainless steels. However, copper, glass, non magnetic stainless steels, and aluminum vessels can be used if placed on a ferromagnetic disk which functions as a conventional hotplate.

A: does cast iron work on induction stove top?

Q: In a simple case such as an object resting upon a table, the normal force on the object is equal but in opposite direction to the gravitational force applied on the object (or the weight of the object), that is, N = m g (\displaystyle N=mg) , where m is mass, and g is the gravitational field strength (about 9.81 m/s on Earth). The normal force here represents the force applied by the table against the object that prevents it from sinking through the table and requires that the table is sturdy enough to deliver this normal force without breaking. However, it is easy to assume that the normal force and weight are action-reaction force pairs (a common mistake). In this case, the normal force and weight need to be equal in magnitude to explain why there is no upward acceleration of the object. For example, a ball that bounces upwards accelerates upwards because the normal force acting on the ball is larger in magnitude than the weight of the ball.

A:
is the normal force on a body always equal to its weight?
