A70 kilogram mountaineer is standing on the summit of mt. everest. the distance between the mountaineer and the center of earth is 6.39 × 10^6 meters. what is the magnitude of the force of gravity acting on the mountaineer? (the value of g is 6.673 × 10-11 newton meter2/kilogram2. the mass of earth is 5.98 × 1024 kilograms.) a. 90.5 newtons b. 179 newtons c. 648 newtons d. 781 newtons

answer is 684 newtons on plato, got 100 on the test :)

684 N

Explanation:

The force of gravity between two objects having mass is given by:

where, G is the gravitational constant, , m is the mass of the man, and M is the mass of the Earth, and r is the distance between two masses,

Thus, the magnitude of the force of gravity acting on the mountaineer is 684 N.

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.
