The answer is; D
Inertia is the tendency of an object to resist change to its velocity and direction. The bigger the mass of an object the higher its inertia. In space, the celestial bodies with a bigger mass have more inertia and have a higher gravitation pull (because they bend space-time more than smaller objects). The gravitational force of bigger objects influences on other celestial bodies and beats their inertia force by causing them to change direction and speed.
Answer:
(<em>n</em> = 7) ⟶ (<em>n</em> = 4)
Explanation:
1. Convert the energy to <em>joules per mole of electrons</em>.
<em>E</em> = 55.1 × 1000 = 55 100 J/mol
2. Convert the energy to <em>joules per electron
</em>
<em>E</em> = 55 100/(6.022 × 10²³)
<em>E</em> = 9.150 × 10⁻²⁰ J/electron
3. Use the Rydberg equation to <em>calculate the transition
</em>
Rydberg's original formula was in terms of wavelengths, but we can rewrite it to have the units of energy. The formula then becomes
where
= the Rydberg constant = 2.178 × 10⁻¹⁸ J
and 
are the initial and final energy levels.
The number of atoms in a molecule varies depending on the specific molecule formed. As a rule of thumb, a molecule must be composed of at least two atoms with no maximum amount of atoms as long as all the atoms in the molecule are bonded together somehow.
Answer:
A. Whenever the population has increased, steel consumption has increased as well.
Explanation:
Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen on the graph is that whenever the population has increased, steel consumption has increased as well.
A critical look at the graph, you will discover that the population and the steel consumption are moving upwards (i.e they are increasing). It's seen that as the population increases, steel consumption increases. This is true because as the population increases, people are building houses, more transportation systems that require steel are being manufactured, more household utensils that are steel products are being fabricated etc; therefore the consumption of steel increases.
for one you could do a bell, ringing noise, then say someone rang it.
For two you could do tunnel, echoing, then say someone yelled and it echoed.
for three you could do a bowl, ringing, spoon hitting it
hope i could help
