If two objects are compared at a certain distance, according to newton’s law of universal gravitation, what is true? complete the sentence using the phrases below.

1. both objects have mass and therefore have
2. lower mass objects have
3. higher mass objects have

less gravitational force.
stronger gravitational force.
a gravitational force.

1: Both objects have mass and therefore have a gravitational force.

2: Lower mass objects have less gravitational force.

3: Higher mass objects have stronger gravitational force.

a. possible errors

d. new questions

explanation:

predictions and planning happen before. a summery comes after. errors you get after investigation and new questions propose what you can look for in the future.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
