The elephant has more inertia than the dog so it takes more force to change the motion of the elephant.
Sodium because according to the atomic size trend of the periodic table. Elements further to the left are bigger while elements tot he right are smaller. This is also do to their charges, Na has a +1 charge meaning it doesn’t pull the electrons as close as the Mg does with its +2 charge.
<span>Answer:
.01 moles of D to .005 moles of L ~ so, .01+.005 = .015 total; using this total value, divide the portions of D and L.
so .01/.015 to .005/.015 ~ 67% D to 33% L.
And thus, the enantiomer excess will be 34%.</span>
<u>Answer:</u> The frequency of the radiation is 33.9 THz
<u>Explanation:</u>
We are given:
Wave number of the radiation, 
Wave number is defined as the number of wavelengths per unit length.
Mathematically,
where,
= wave number = 
= wavelength of the radiation = ?
Putting values in above equation, we get:
Converting this into meters, we use the conversion factor:
1 m = 100 cm
So, 
- The relation between frequency and wavelength is given as:
where,
c = the speed of light = 
= frequency of the radiation = ?
Putting values in above equation, we get:
Converting this into tera Hertz, we use the conversion factor:
So, 
Hence, the frequency of the radiation is 33.9 THz
Answer:
When there is heat at the bottom of this air or water, the air or water molecules in contact with the heat start to move, and the molecules spread apart. The heated air or water becomes less dense. It rises up until it gets to air or water with the same density as it has, and when it gets there, it pushes the air or water that was there out of the way. At the same time, new air or water fills the space that was vacated when the heated molecules rose up. The air or water that gets pushed out of the way falls down. This sets up a circular motion. Air or water is heated at the bottom, travels to the top, cools, gets denser, falls, is heated again and the whole cycle starts again. Convection does not occur in space because there is no gravity. Ovens work by convection. The heating coils at the bottom of the oven heat the air which climbs to the top, cools slightly, and falls down again.
