The sun emits __________ radiation, but it is radiated back off of planetary bodies as __________ radiation.
andriy [413]
<span>The answer to your question: <span>The sun emits shortwave radiation, but it is radiated back off of planetary bodies as longwave radiation.  </span></span>  
<span>
Explanation: The sun emits shortwave radiation, wherein it’s extremely hot and is filled with more energy compared to the radiation emitted by planets. This also comes in the form of light. However, once this becomes absorbed by planetary bodies, it turns into longwave radiation. A good example is the earth’s atmosphere emitting energy (longwave radiation), which is energy originally coming from the sun (shortwave radiation).</span>

Describe how air resistance would affect a falling object ​
aivan3 [116]

Answer:

With air resistance, acceleration throughout a fall gets less than gravity (g) because air resistance affects the movement of the falling object by slowing it down. How much it slows the object down depends on the surface area of the object and its speed

If A.B=A.C<br>does this imply that B must be equal to c ? <br>I need answer with example please ​
Leno4ka [110]

Answer:

Yes

Explanation:

Consider\ three\ variables\ a,b\ and\ c.\\If,\\ab=ac\\a*b=a*c\\We\ may\ now\ divide\ the\ LHS\ and\ RHS\ by\ a,\\Hence,\\\frac{a*b}{a} =\frac{a*c}{a}\\Hence,\\b=c

Ex: \\Consider\ a=5, b=6.\\Hence\ if,\\a*b=a*c\\5*6=5*c\\Hence,\\30=5c\\Hence, c=\frac{30}{5}\\c=6\\As\ b\ also\ equals\ to\ 6,\\b=c
