Gravity on earth is 9.8 m/s2, and gravity on jupiter is 23.1 m/s2.

so, if the mass of a rock is 70 kilograms, its weight on earth is
newtons and its weight on jupiter is
newtons.

Weight on Earth = 686 N

Weight on Jupiter= 1617 N

Explanation:

The weight on the planet can be determined by the expression shown below as:

Thus, For Earth

Acceleration Gravity = 9.8 m/s²

Mass = 70 kg

So,

Weight on Earth = 686 N

For Jupiter

Acceleration Gravity = 23.1 m/s²

Mass = 70 kg

So,

Weight on Jupiter= 1617 N

The weight on Earth is 686 newtons and its weight on Jupiter is 1617 newtons.

answer: i would say b.

explanation:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
