Explanation:
Using the Newton's laws, we can find the force F required for lifting the book having mass (m) and acceleration due to gravity (g) that is ;
and, the change in the position of the book that is Δx (Height)
→ Δx = Final position - Initial position
which is only the height, then the amount of work done will be calculated by :
W= mgh
m = Mass of the Body
g = Acceleration due to Gravity
h = Height of Body being displaced
3. what type of ion is

Answer:
1. Univalent negative ion (Cl-)
2. Divalent negative ion (O2-)
3. Divalent positive ion (Mg2+)
4. Divalent negative ion (S2-)
5. Divalent negative ion (CO3)^2-
6. Univalent negative ion (NO3) ^-
V equals one-third times pi times r squared times h
V = s3
V = πr2h
Answer: Option 1 --- V equals four-thirds times pi times r cubed
Explanation:
b)hydrogen and chlorine
c)nitrogen and oxygen
d)sulfur and oxygen
Ionic compounds are formed between a metal and non-metal. An ionic compound can be formed between strontium and chlorine and the compound is called strontium chloride.
Ionic compounds are formed by losing an electron from an electropositive element to an electronegative element. Thus between a metal and non-metal.
Ionic bonds are the strongest bond and it creates partial charges in the compound since the bonded electrons are attractively pulled towards the more electronegative element in the bond and thus the metal ions gets a positive charge and nonmetal gets a negative charge.
Covalent bonds are formed by sharing electrons between two nonmetals. Hydrogen and chlorine forms the covalent compound HCl. Similarly, nitrogen and oxygen always forms covalent bonds.
Sulfur and oxygen are comparable in electronegativities and thus forms a covalent bond. Therefore, the elements which forms an ionic compound are strontium and chlorine forming strontium chloride. Hence, option A is correct.
