I think it is 3. <span> radiation received from the sun</span>
Answer:
c
10 A
Explanation:
Use the equation that calculates voltage: V = IR (That's capital "i")
"V" represents voltage. It's measured in the unit volts, the symbol V.
"I" represents current. It's measured in amperes, the symbol A.
"R" represents resistance. It's measured in ohms, the symbol Ω.
From the question, we know the source is 120 V and the resistance is 12Ω.
Substitute V = 120V, R = 12Ω into the equations. Isolate "I" to find the current.
V = (I)(R)
120V = (I)(12Ω)
I = 120V ÷ 12Ω
I = 10A
Therefore:
The current of a 12-ohm hair dryer that is connected to a 120-volt power source is <u>10 A (10-amps)</u>.
A common activity like cooking a meal can use many natural <u>Ingredients </u>
<h3>Ingredients </h3>
Ingredients are substances combined to make a particular mixture such as a meal. most of the ingredients used for the preparation of a meal are sourced naturally.
In cooking different recipes of a meal the use of specific ingredients for each recipe differentiates the recipes.
Therefore we can conclude that cooking a meal requires the use of natural ingredients.

An atom with two valence electrons in the periodic table belongs to the alkaline earth metals or 2nd group. The element with atomic number 17 is chlorine with 7 valence electrons. Ionic compounds are formed between the atoms of elements with high electronegativity difference. More the difference, more they are likely to form ionic bond.
Thus in this case, the most likely formed ionic compound will be with alkaline earth metal with high electropositivity. The highest electropositive element in group 2 is barium thus, ionic compound formed will be
In , barium will donate its two electrons, one to each chlorine atom. The resultant compound will be ionic in which all the atom have complete octets.
Answer:
Explanation:
Heat energy reaches other planets and satellites of the solar system through the process called radiation.
In this process , the heat energy travels in the form of electromagnetic waves which do not require any material medium . It is so because it is a non mechanical wave . Hence heat energy reaches earth or moon even when there is no material medium between sun and the moon . Other mode of transfer of heat requires medium like solid or liquid or gas to travel from one point to another .
