When you feel warmth without touching an object directly but are close to it, what type of heat transfer are you experiencing?
Latent heat release
Thermal conductance (conduction)
Radiant heat (radiation)
Convective flow (convection)
If electron initially rest ejected toward north but then deflected eastward what must be orientation Earth's magentic ffield near expulsion point?
North-south indicating would head back towards origin instead.
West-west suggesting southerly deviation motion...
South-to-north such deflection results from west-east component earth's field.
East-east implies northern deflection...
Which term describes the amount of electric charge in the universe?
Transfer
Creation
Conservation
Dispersal
If two objects are rubbed together and one becomes positively charged, what happens to the other object?
It remains neutral
It becomes negatively charged
It also becomes positively charged
Its mass increases
If two capacitors with different capacitances are connected in series, how does the equivalent capacitance compare to the smallest individual capacitor?
Equal to the sum of both individual capacitors
Equal to the average of both individual capacitors
Greater than the largest individual capacitor
Less than the smallest individual capacitor

How does increasing only the distance between two point charges in vacuum affect their mutual electrostatic force without altering any other properties?
Increasing distance leads to linearly decreasing electrostatic forces reflecting direct proportionality between them ().
It results in no change on their mutual electrostatic force since individual charges do not vary with distance changes alone.
It causes an exponential increase in mutual electrostatic force as distance increases due to inverse proportionality between force and distance.
The mutual electrostatic force decreases according to Coulomb's law as distance increases squared inversely affects force magnitude ().
