How do you solve Vmax and Km? v = Vmax – Km x v / [S] y intercept = Vmax. gradient = -Km. x intercept = Vmax / Km. What is the unit of KM? Kilometre (km), also spelled kilometer, unit of length equal to 1,000 metres and the equivalent of 0.6214 mile (see metric […]
Will a high pH kill fish?
Will a high pH kill fish? Very high (greater than 9.5) or very low (less than 4.5) pH values are unsuitable for most aquatic organisms. Young fish and immature stages of aquatic insects are extremely sensitive to pH levels below 5 and may die at these low pH values. High pH levels (9-14) can harm […]
What is difference between series and parallel circuit?
What is difference between series and parallel circuit? In a series circuit, all components are connected end-to-end, forming a single path for current flow. In a parallel circuit, all components are connected across each other, forming exactly two sets of electrically common points. Which is an example of a parallel circuit? An example of a […]

Why do elements have different line spectra?
Why do elements have different line spectra? The energy levels that are allowed for each atom depend upon the number and arrangement of protons and electrons in the atom. As each element has different energy states available to it, each element releases photons of different color when its atoms return to their lower energy states. […]
What is the internal resistance of a 12v battery?
What is the internal resistance of a 12v battery? 500 ohms What would be the symptoms of a battery with high internal resistance? High resistance, current is restricted, voltage drops on load; battery heats up. Figure 1: Effects of internal battery resistance. A battery with low internal resistance delivers high current on demand. High resistance […]
How much heat does it take to boil water?
How much heat does it take to boil water? The boiling point of water is typically considered to be 100 °C or 212 °F. Pressure and a change in the composition of the liquid may alter the boiling point of the liquid. High elevation cooking generally takes longer since boiling point is a function of […]
