Inertia in a sentence?
Inertia is, essentially, the body's resistance to change. An example sentence would be: Without inertia, we would be all over the place.
Results for quarters and feathers fall at the same speed?
Quarters and feathers would only fall at the same speed in a vacuum. In air, the quarter would fall faster, as it has less air resistance.
How would the shape of a car change the speed?
different shapes would mean different air resistance and weight both of which slow the car down the more there is
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
What do you measure to find an objects inertia?
Inertia in physics is generally defined as resistance to change in velocity and it is measured as a change in momentum. (p is momentum, so change in momentum would be Δp, measured as Δp = m*Δv)
How would the results of the starch hydrolysis change if glucose was added to the medium?
The starch is a different media. Therefore, by adding glucose to the medium it would throw off the results of the starch hydrolysis significantly.
What does the term factor mean in science?
Something that helps to make up the final results of an experiment, and taking it away or adding stuff on to it would therefore change the final results of the experiment.
How would you extend the range of a voltmeter and ammeter?
if we would like to expand the range of voltmeter we should change the voltmeter resistance even to be appropriate . we should use a variable resistance to control of its value . I would extend the range of a voltmeter by adding resistance in series with it. I would extend the range of an ammeter by connecting resistance in paerallel with it.
Would adding an electron to hydrogen change its mass?
no, it would change its charge not its mass.
How would you explain the experimental results by adding quantum theory of light?
I would not even begin to plan an explanation until I knew what the experimental results are.
Does current effect the resistance in an electric series circuit?
The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.
Would adding heat to the reaction change the height of the curve?
yes.because adding heat would increase the Products and lowering the Reactants.
Which results in a more valuable product -- adding or substracting protons from gold nuclei?
adding and subtracting protons from a gold atom would no longer make it gold.
Is adding sugar to cereal a physical or chemical change?
It would be physical change.
How would you cause a chemical change to vinegar?
For example adding a base.
What would the current be if an extra battery was added to a circuit?
If you add more batteries in series, the voltage would increase. This would drastically change the circuit. Normally this should also produce more current.The effect of adding more batteries in parallel is insignificant for many circuits. Adding more batteries in parallel is like lowering a battery's internal resistance - which, for many circuits, can be neglected.Example: The battery's internal resistance can be neglected; the battery gives a voltage of 12 volt, you connect it to a resistance of 2 ohm. According to Ohm's law, that will give you a current of 6 ampere. Note that the battery capacity does not enter the calculation! Adding a second battery (of the same kind) will produce the same voltage, thus, the same current.If you add more batteries in series, the voltage would increase. This would drastically change the circuit. Normally this should also produce more current.The effect of adding more batteries in parallel is insignificant for many circuits.

Is adding HCl to Mg physical change?
No. There is a change in substance taking place, so it would be considered a chemical change.
