1. The problem is to simplify or understand the expression $\frac{2v}{\phi \cdot h}$.\n\n2. This expression represents a fraction where the numerator is $2v$ and the denominator is the product of $\phi$ and $h$.\n\n3. The formula is already in its simplest form unless we have specific values or relationships between $v$, $\phi$, and $h$.\n\n4. Important rules: when dividing by a product, you keep the numerator as is and multiply all terms in the denominator.\n\n5. If you want to rewrite or factor, you can write it as $$\frac{2v}{\phi h}$$ which means $2v$ divided by the product of $\phi$ and $h$.\n\n6. Without additional context or values, this is the final simplified expression.
