Pressure and Density
Define pressure and what is the formula for it?
The amount of force applied to the surface of an object. The formula is force divided by area
Describe the flow of electrons in a conductor
In a conductor electrons move freely in the material’s structure
Define density and what is the formula?
The measurement of how tightly a material is packed together. The formula is mass/volume
Explain what happens when a positively charged object is brought near a negatively charged object.
They will attract each other and they will neutralize each other
Describe how density affects whether a object will float or sink.
A object with a higher density than the liquid with sink, but a object with a lower density than the liquid will float.
What is the symbol for an light bulb
Calculate the density of a metal cube with a mass of 200 grams and a volume of 50cm³
the density is 4g/cm3
Whats the symbol for a resistor
A box with a line on both sides
A column of water has a height of 5 meters. If the density of water is 1000 kg/m³, calculate the pressure at the bottom of the column.
using formula (pgh) the answer is 49,050 pascals
g=accerlation (9.81)
What happens when a negatively charged rod is brought near a nuetral object
the nuetral object will attract to the negatively charged rod
