The combination of symbols that shows the ratio of elements
in a compound is called chemical formula. A chemical formula is one of the ways
in expressing information about the ratio and proportion of atoms that consists
a particular chemical compound. This is done by using a single line pf chemical
symbols of elements, numbers, and sometimes parentheses, comma, dashes,
brackets and sometimes the positive and negative sign. Chemical formula can
completely specify the simplest structure of molecules and chemical substances.
The answer is D. Isotopes.
Hope that helped.
Answer:
angle is 19.85°
Explanation:
given data
grade = 36.1 %
vertically distance y = 36.1 m
horizontal distance x = 100 m
to find out
angle
solution
we know that according to question here
it make a triangle shape that contain 100 m base and height 36.1 m
and make angle with base is θ
so by triangle we know here
tanθ = y/x ..........1
so we now put x and y and find θ
tanθ = 36.1 / 100
tanθ = 0.361
θ = 19.85°
so angle is 19.85°
Answer:
B I believe, because the axe is wedged into the log
Work = Force * distance
W = Fd
Given F = 500 N, d = 10 m
W = (500)(10)
W = 5000 J
The work done is 500 Joules. The time of 4 s is irrelevant in this case.
