Answer :
the mass on mercury of a thing that weighs 784 n on the surface of the earth (a) 80.0 kg (b) (b) 48.0 kg (c) 118 kilogram (d) 26.0 kg (e) (e) The body on Mercury weighs 80 kg because there is not enough data to compute its mass.
What is the mass of an object in mercury?
500 divided by 10 equals 50 kilograms, where mass is defined as weight divided by gravity. 80 kg weighs 784 N x 0.39, or 306 N, because Mercury's surface gravity is 0.39 that of the Earth's (table 10-1). The weight of the individual on Mercury can be determined using Newton's universal law of gravitation. Thus, the person's weight on Mercury is roughly 185 Newtons. [tex]Fw = m * 9.8 m/s^2[/tex]. Fw equals 30 kg times [tex]9.8 m/s^{2} \\[/tex] to 294 N. Divide by gravity [tex](9.8 m/s^{2} )[/tex] to convert from weight to mass.
If we are aware of the object's force and acceleration, we may use Newton's Second Law of Motion to determine the object's mass. Always keep in mind that force is equal to mass times acceleration. In order to determine the mass of the object in issue, we must divide the force by the acceleration.

The mass of an object on Mercury that weighs 784 N on Earth is 80.0 kg. This is because mass remains constant regardless of the gravitational force of the body upon which the object is placed.
To find out the mass of an object on Mercury that weighs 784 N on the Earth's surface, we can use the formula for weight (w), which is the product of mass (m) and acceleration due to gravity (g): w = mg. On Earth, g is 9.80 m/s². Therefore, the mass (m) of the object can be calculated using the Earth's gravitational force as follows: m = w/g = 784 N / 9.80 m/s² = 80 kg.
Now, since the mass of an object remains constant regardless of location, the mass of the object on Mercury would still be 80 kg. However, due to Mercury's different gravity (3.78 m/s²), the weight of the object would change, but not the mass.
So, the correct answer is (a) 80.0 kg.
