Understanding the Units: Joule per Centimeter & Exanewton
What is Joule per Centimeter (J/cm)?
A joule per centimeter (J/cm) represents energy (joules) distributed over a distance (centimeters). It is commonly used in fields like materials science, mechanics, and engineering when measuring force over a certain distance.
1 Joule per centimeter = 100 Newtons (N)
This means that when energy is applied over a distance of 1 cm, it corresponds to a force of 100 newtons.
What is an Exanewton (EN)?
An exanewton (EN) is an extremely large unit of force, part of the metric system:
1 Exanewton = 10¹⁸ Newtons (N)
Exanewtons are used in astronomical calculations and extreme physics scenarios, such as measuring planetary forces.
Conversion Formula: 0.70 J/cm to Exanewton (EN)
To convert joule per centimeter (J/cm) to exanewton (EN), we use the fact that: 1 J/cm=100 N1 \text{ J/cm} = 100 \text{ N}1 J/cm=100 N
Since we are given 0.70 J/cm, we first convert it to newtons: 0.70×100=70 N0.70 \times 100 = 70 \text{ N}0.70×100=70 N
Now, to convert newtons to exanewtons (EN), recall: 1 EN=1018 N1 \text{ EN} = 10^{18} \text{ N}1 EN=1018 N
So, converting 70 N to exanewtons: 70÷1018=7.0×10−17 EN70 \div 10^{18} = 7.0 \times 10^{-17} \text{ EN}70÷1018=7.0×10−17 EN
Final Answer:
0.70 J/cm = 7.0 × 10⁻¹⁷ Exanewtons (EN)
