Answer:
what is it on? like name one of the questions
Explanation:
Answer:0.6kw
Explanation:
Power=force×velocity
Power=20×30=600w
In kw it's going to be 600/1000=0.6kw
Answer:
Explanation:
Change in velocity considering the x component will be
Final velocity-Initial velocity
Change in velocity considering the y component will be
Final velocity-Initial velocity
Resultant change in velocity
Acceleration= change in velocity per unit time hence
Answer:
No

Answer:
Explanation:
Polyatomic ions are ions that contain more than one atom in each one of the ions.
Ionic compounds are made of cations (positive ions) and anions (negative ion). By convention, the cation is written before the anion.
List the ions in each compound:
<h3>CaCO₃</h3>
Cation: ,
Anion: .
is a monatomic ion for it contains only one atom in each ion.
is a polyatomic ion for it contains four atoms (one C atom and three O atoms) in each ion.
<h3>NaF</h3>
Cation: ,
Anion: .
Both and are monatomic for they contain only one atom in each ion.
<h3>FeO</h3>
Cation: ,
Anion: .
Both and are monatomic for they contain only one atom in each ion.
<h3>CaCl₂</h3>
Cation: ,
Anion: .
Both and are monatomic for they contain only one atom in each ion.
<h3>NaOH</h3>
Cation: ,
Anion: .
is a monatomic ion for it contains only one atom in each ion.
is a polyatomic ion for it contains two atoms (one O atom and one H atom) in each ion.
