Answer:
a.
ionic compounds
Explanation:
The above statement is False
The weight of an object is the force it experience by the gravitational pull of the planet. The gravitational pull by earth is greater than that from moon. This leads to greater weight in earth than in moon.
Gravitational force is a kind of force by which an object attracts other objects into its center of mass. The force exerted between the objects depends on the mass and distance between them.
Earth exerts a gravitational pull to every objects on its surface and that's why we are standing on the ground. We experience a weight downwards due to this force.
The acceleration due to gravity in earth = 9.8 m/s²
g in moon = 1.63m/s².
then weight = m g
the weight of a 10 kg iron bar in earth is 98 N and that in moon will be 16.3 N.

Answer:
The decrease in the downward force that a mass of iron can exert on the moon versus the force it exerts on earth is due to:
Explanation:
To recognize the calculation within the statement, you must know that the Newton unit is equal to:
And that the gravities of the Earth and the Moon are:
Finally, you must know the force formula (since we are talking about a descending force):
Since the mass in both cases is the same (10 kilograms), the variation in acceleration will provide different values of descending force, as shown below, replacing the values:
As you can see, when it comes to force, the less acceleration (in this case less gravity), the lower the downward force will be with a mass of equal weight.
B- Solid
C- Liquid
For Future Students The Answer is A- Gas I can confirm this is the answer because I took the test. Hope this helped.
Column A: x-axis, input, domain
Column B: y-axis, output, range
Those are other ways to describe them
hope i helped:)
