Question

Does wt of object differ at sea level coal mine and mountain

Answer 1

Answer:

yes

Explanation:

because gravity varies from place to place.

Answer 2

Answer:

in simpler terms W1 < W2 > W3 is the answer[option c is incomplete}

as coal mine and top of of mountain have   lesser force of gravity  

but for furthur explanation read the followng paragraph

Fg = GMm/d^2

G is the gravitational constant. M is the mass of the earth. m is the object’s mass. d is the distance from the center of the earth to the object. In this equation, the force is inversely proportional to the square of the distance from the center of the earth to the object. This means the force is greatest when the distance from the center of the earth to the object is the least. If we assume that the coal mine is below sea level, the force is greatest inside the coal mine, and decreases at the object moves upward. In order from greatest to least, the order is W1, W2, and W3. If the coal mine is above sea level, the order from greatest to least, the order is 2, W2, W1, and W3. One of these must be correct.

plzzz... mark as brainliest answer. plz...
