Bill nye the science guy/ motion video worksheet (11) The scale is measuring the pull of the Earth's ___ on the apples mass.
(12) We measure mass in ___ or kilograms
(13) In ___ the laws of motion still apply
(14) Even if it does not seem like it, all of us here are moving pretty ___.
(15) Everything in the ___ is all in motion
GRAVITY, GRAMS, FORCES, MASS, FAST, UNIVERSE, SPACE, ACTION
I did 1-10 I need 11-15 still
9th grade science :)

11) gravity

12) grams

13)

14) fast

15)space

11)To move a mass you need a force.

Force = mass x acceleration

12) An object at rest stays at rest and an object in motion stays in motion unless acted on by an outside force.

13)For every action there is an equal and opposite reaction.

14) fast

15)False

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.  

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
