The word "static" would be known to be friction as air rushing against an airplane
Answer:If you look at the image of the toy car in the mirror, it will appear to be the same ... However, there is a virtual focal point on the other side of the mirror if we follow them ... Concave mirrors, on the other hand, can have real images. ... Naturally, in concave mirror, the closer the image to the mirror, the bigger the image formed.
21.75 Miles Per Hour
I got this by multiplying 7.25(3) because I know 20 minutes is 1/3 of 1 he
Answer:
A. 20 N
Explanation:
Weight of the book = mass × acceleration due to gravity
= 2 × 10
= 20 N
First, we need to know the amounts of the elements in the compound.
Tin (Sn)= 5.28 g
Fluorine (F) = 8.65 - 5.28 = 3.37 g
Convert these to units of moles by dividing the molar masses.
Tin (Sn)= 5.28 g / 118.71 g/mol = 0.044 mol
Fluorine (F) = 3.37 g / 19.00 g/mol = 0.177 mol
Divide both by the least number of moles of the two.
Tin (Sn)= 0.044 mol / 0.044 mol = 1
Fluorine (F) = 0.177 mol / 0.044 mol = 4
Therefore, the empirical formula would be:
SnF4
