Answer : Option A) HF.
Explanation : Assuming the complete question as per the attachment.
H-F bonds are formed because of hydrogen bonding between H atom and F atom and is considered to be strongest amongst the rest other options given.
As given in the table it is clear that the molar mass of HF molecule is the lowest. It shows that, when dispersion increases in the molecule molecular weight also increases.
Answer:The height of First Copy is 20 cm.
Step-by-step explanation:
Given:
Original Height = 25 cm
First copy is reduce to 80% of Original height.
Therefore to find the height of first copy can be find out by multiplying 80 with original height and then dividing by 100.
∴ Height of First Copy =
Hence Height of first copy is 20 cm
Now Another copy is reduce to 85% of First Copy.
Therefore to find the height of another copy can be find out by multiplying 85 with first copy height and then dividing by 100.
∴ Height of Another Copy =
Hence Height of Another copy is 17 cm
