Answer:
A model rocket is launched with an initial upward velocity of 215 ft/s.
Explanation:
The magnitude of the gravitational attraction is 
.
Explanation:
The magnitude of the gravitational force between two objects is given by
where
is the gravitational constant
m1, m2 are the masses of the two objects
r is the separation between them
In this problem, we have
is my mass
The mass of the mountain is 100 million tons, and keeping in mind that
1 ton = 1000 kg
The mass of the mountain is
The distance between me and the mountain is
r = 1 km = 1000 m
Therefore, the gravitational attraction is

Answer:
The correct option is D
Explanation:
Generally, thermal and electrical conductivity is affected by valence electrons in an atom. These valence electrons carry electric charges (or conduct heat as the case may be) throughout the atom. The fewer the valence electrons, the higher its conductivity - this is as a result of free movement within the atom. The higher the valence electrons, the lesser its conductivity and when the outermost electrons have completely filled the outermost shell, the atom would be an insulator as there won't be carriers of electric charges.
Hence, from the above, sodium would be expected to have the highest electrical and thermal conductivity because it has just one electron in it's outermost shell
Answer:
dependent: the outcome of the experience
independent variable: everything literaly.
Independent is where you change some variables and see the result
Dependent is literaly the result, or the outcome dependent on the exprience.
