i think it's 3 because there aren't any indexes so that leaves us with one atom of Ca, one atom of O, and one atom of H
For water to freeze it would need to be 32 degrees Fahrenheit or 0 degrees Celsius.
A hair dryer converts "electrical energy" to "thermal energy".
Option: C
<u>Explanation</u>:
The "electricity" is converted to "heat energy" in a "wire coil". Here electricity process "air" out of "the hair dryer" with the help of forced convection. Most hairdryers use a nichrome wire coil that will not oxidize when heated and allowing it to "blow" the hair dry with high temperature air which speeds up evaporation. Thus "wire heats" the "air faster", in most of the "hair dryers" the "air" is only in "the barrel" for "half of a second".
Answer:
light
According to Newtonian gravity, light is not affected by gravity, as light is massless. Einstein's law E = mc 2, immediately suggests that light is affected by gravity. This is indeed the case and has experimentally be observed via gravitational lensing and other effects.
Explanation:
I thought I'd just answer here as well so I can get a couple extra points :)
I'm super glad I helped <3
