Why does tungsten's resistancechange as it gets hotter?

When heat is supplied to tungsten or for that matter any metal its molecules start vibrating more vigorously and thus collide with each other thus opposing the flow of electrons to a greater extent and so resistance is increased


Does the resistance go higher or lower when a thermistor gets hot?

the therminster will get hotter when the resistance is lowed


Why does resistance increase in a series circuit?

Depends - in the real world as a resistor gets hotter (current flowing through it) its resistance increases.


Does the resistance of a light bulb filament change after the light has been turned on?

The electrical resistance of a light bulb increases when it is turned on As a resistor, the tungsten light bulb has a positive resistance coefficient. This means that the electrical resistance goes up when the filament becomes hot. For example, a 100 watt light bulb operated at 120 volts - it does not matter if it is AC or DC for this calculation - will have a resistance of 144 ohms when hot and draw .833 ampere. When cold the filament typically has a resistance of only 10 ohms which increases as the filament heats up.

What will happen to the temperature of the rockets nose cone as it moves through the air?

it gets hotter the faster it goes the hotter it will get (this involves friction) or another way of saying it is: The temperature will change due to friction, the faster it goes the hotter it gets (friction is present)
