How much should a car battery drain overnight? If its a new battery with a good charging system 12.8 to 12.6 is what you should expect. The problem is in order to save fuel a lot of charging systems only charge your battery 80% to save fuel. How do I know if I need a […]

Does bike weight affect speed? (A heavier bike won’t make up the entire difference, especially if the downhill requires breaking, but it will accelerate slightly faster than a lighter one.) A much more efficient—and economical—way to lighten your load is to shed body weight, says Gourley, not bike weight. Why is it hard to pedal […]

What is the volume of an ideal gas? What is the volume of 1 mole of an ideal gas at STP (Standard Temperature and Pressure = 0 °C, 1 atm)? So, the volume of an ideal gas is 22.41 L/mol at STP. This, 22.4 L, is probably the most remembered and least useful number in […]

Which graph is used to show change in a given variable? line graph What are variables in a chart? Variables control charts are used to evaluate variation in a process where the measurement is a variable–i.e. the variable can be measured on a continuous scale (e.g. height, weight, length, concentration). Which graph would be best […]

Does E6000 work on epoxy? Can you use e6000 on resin? You can also place the finding into the resin as it sets up. If you’re not mixing up a second batch of resin, you can use a strong adhesive such as E6000 (although it’s stinky), or ZapAGap, a great super-glue. Which is better JB […]

Is kg/m 3 the same as g ml? The SI standard is really kg / m3. 1 kg/dm3 = 1 kg/L = 1000 g/1000 cm3 = 1 g/cm3 = 1 g/ml (water). Water as the reference with its highest density at 3.98 °C is ρ = 1 g/cm3. The correct SI unit is ρ = […]

How do you find order of magnitude? Order of magnitude is usually written as 10 to the nth power. The n represents the order of magnitude. If you raise a number by one order of magnitude, you are basically multiplying that number by 10. If you decrease a number by one order of magnitude, you […]

What is one example of an unseen source exerting a force? Unseen Sources and Receivers of Forces It is not always easy to tell what is exerting a force or what is receiving a force. For example, you cannot see what exerts the force that pulls magnets to refrigerators. You cannot see that the air […]
