How far should your low beams go? Do not overdrive your headlights. Your headlights only let you see about 350 feet ahead. Be sure you are driving slow enough to stop or turn if needed. Use your low beams when you come within 500 feet (about one block) of an oncoming vehicle. How many feet […]
Why do we use zero correction?
Why do we use zero correction? Zero correction is used in an instrument for removing the zero error. What is zero error and its correction? Zero error correction arises due to error in the measuring instrument. It occurs when the first marked line of the instrument like vernier calliper, micrometer screw guage etc. do not […]

How does electricity flow in a circuit draw an open circuit?
How does electricity flow in a circuit draw an open circuit? The electric circuit in which there is a gap in the connections between the terminals of the cell, wires and the bulb, etc is called an open circuit (or incomplete circuit). Electricity does not flow through an open circuit because there is a gap […]
What happens when stomata are open?
What happens when stomata are open? When stomata are open, water vapor and other gases, such as oxygen, are released into the atmosphere through them. A number of factors can affect the exchange of gases between a leaf and the atmosphere. What allows stomata to open and close? Specialized cells known as guard cells surround […]
Which of the following are examples of hydrolysis reactions?
Which of the following are examples of hydrolysis reactions? Dissolving a salt of a weak acid or base in water is an example of a hydrolysis reaction. Strong acids may also be hydrolyzed. For example, dissolving sulfuric acid in water yields hydronium and bisulfate. Which is a hydrolysis reaction? Usually hydrolysis is a chemical process […]

What are the two main types of calorimeter?
What are the two main types of calorimeter? Some of the most common types are adiabatic calorimeters, oxygen bomb calorimeters, and differential scanning calorimeters (DSC). An adiabatic calorimeter is used to measure a “runaway reaction”, any heat generated by the sample under test causes the sample to increase in temperature, fueling the reaction. How do […]
