The motion of objects can be quite complex. The motion of this frog is an example. Suppose that the frog moves from one lily pad

to the other in 1 second.
Describe the motion of the frog as it makes one round trip between the two lily pads. Use the terms speed, velocity, displacement, and distance in your answer.

Answer:

The speed of the frog is 1m per second the velocity is he can turn and jump in a different direction in 1 second the distance is 1m and there is no displacement. I'm pretty sure this is right

Calculate the percentage of the void space out of the total volume occupied by 1 mole of water molecules. The density of water i
gtnhenbr [62]

Answer:

The percentage of the void space out of the total volume occupied is 93.11%

Explanation:

A mole of water contains 2 atoms of hydrogen and 1 atom of oxygen.

To calculate the volume of a mole of water, we calculate 2 times the volume of the hydrogen atom and 1 times the volume of the oxygen atom

Let's calculate this one after the other.

For the hydrogen, formula for the volume will be

V_{hydrogen = 2 × 4/3 × π × r_{H}^{3}

where r_{H}^{3} = 37 pm which is read as 37 picometer (1 picometer = 10^-12 m) = 37 × 10^{-12} meters

Volume of the hydrogen = 8/3 × (37 × 10^-12)^3 = 4.05 * 10^-31

we multiply this by the avogadro's number = 6.02 * 10^23

= 4.05 * 10^-31 * 6.02 * 10^23 = 2.6 * 10^-8 m^3

We do same for thr oxygen, but this time we do not multiply the volume of the oxygen by 2 as we have only one atom of oxygen

Volume of oxygen = 4/3 * π * (73 * 10^-12) ^3 * avogadro's number = 9.81 * 10^-7 m^3

adding both volumes together, we have 1.24 * 10^-6 m^3 or simply 1.24 ml ( 0.01 m = 1 ml)

Dividing the molar mass of one mole of water by its density, we can get the volume of 1 mole of water

= (18g/mol)/(1 g/ml) = 18 ml/mol

Now we proceed to calculate the volume of void = Total volume - volume of molecule = 18 - 1.24 = 16.76 ml

Now, the percentage of void = volume of void/total volume * 100%

= 16.76/18 * 100% = 93.11%

What may happen if the oceanic plates stop moving?
My name is Ann [436]
If all plate motion stopped, Earth would be a very different place. The agent responsible for most mountains as well as volcanoes is plate tectonics, so much of the activity that pushes up new mountain ranges and creates new land from volcanic explosions would be no more. The volcanoes of the Pacific Ring of Fire, in South and North America, Japan, the Philippines, and New Zealand, for example, would shut off, and the steady southeastward migration of volcanic activity along the Hawaiian Islands would stop. Volcanism would just continue on the big island. There would also be far fewer earthquakes, since most are due to motion of the plates.

Which compounds give a 1h nmr spectrum with two signals in a ratio of 2:3?
spayn [35]

Four option are provided as,

CH3CH2OCH2CH3

CH3CH2Cl

CH3CH2CH3

CH3OCH2CH2OCH3


CH3CH2Cl having 2 peaks of H NMR as 1st peak for quartet of 2 H and 2nd peak of triplet of 3 H and thus the ratio of both the peak is 2 :3 as the ratio indicates the number of hydrogen corresponds to each peak.
