Answer:
221754385964.9123
Explanation:
Convert miles to nanometer
1 mile = 1.6 km
1 km = 1×10³×10³×10³×10³ nm
1 mile = 1.6×10¹² nm
So,
158 miles = 158×1.6×10¹² = 252.8×10¹² nm
Length of each molecule = 1140 nm
Number of molecules = Total length / Length of each molecule
There are 221754385964.9123 number of molecules in a stretch of 158 miles
Answer:
Explanation:
Sum of the vertical forces is zero
F₁ + F₂ - Z = 0
Z is negative since Z acts in the opposite direction from F₁ and F₂
30 + 20 - Z = 0
Z = 50
