Answer:
Please see below as the answer is self-explanatory.
Explanation:
- The visible range extends roughly from 400 nm (violet) to 700 nm (red).
- Below the violet is the ultra-violet spectrum (with higher energy) and above red, we have the infra-red spectrum.
- The wavelengths in the range of 650 to 690 nm have red as the dominant color.
Answer:
On molecules of PH3, there has to be 3 atoms.
Explanation:
The Element Hydrogen (H) has 3 attoms.
The Element Phosphorus (P) has 1 atom.
These two created into the molecule PH3, would have to have only 3 attoms because they are asking how many hydrogens atoms are in the molecule PH3.
Displacement is defined as the net distance traveled through the entire trip. That is to say, if you compared where you are at the end of the walk to where you were at the start, the displacement is the distance between those two points.
Distance doesn't compare the two end points. It just counts the total distance you've walked throughout your trip.
Lisa walks once around the block. She starts and ends at the same place. Her displacement is therefore 0 m.
But she has walked 1 mile throughout the trip. Her distance walked is therefore 1 mile.
