Can you make a bulb glow more brightly by adding a second battery?

Yes, two batteries will make a light bulb brighter than one, provided that the batteries are placed in series. The brightness of the bulb is determined by the voltage, and placing two batteries in series rather than just using one increases the voltage.

How can you make a bulb in a circuit brighter?
you can make it brighter by adding another battery/cell
What will happen to the electric pressure differences across the battery terminals when a second long bulb is added in parallel to a single long bulb connected to a fresh battery?
there will be little or no change
Will adding more batteries to a simple circuit will make the bulb?
If you add another battery in series with the first one, then the bulb willglow brighter, and may burn out if you carry things too far.If you add another battery in parallel with the first one, then the brightnessof the bulb won't change, but the battery will last twice as long.
Three bulbs of different watts are connected in series - which bulb will burn brightly - the higher wattage bulb or the lower?
lower wattage bulb
How can you demonstrate that a light bulb emits electrons by thermionic emission?
Edison was said to have noted this emission when a wire paralleling a light bulb filament showed current flow if the filament was more negaive than the wire, but not if the filament was more positive than the wire. Note that the wire is not touching the filament. The wire was inside the bulb with the filament. First Edison lit the bulb with a simple battery circuit. Then the wire was connected to a current meter and other terminal of the current meter to a second battery and the other end of the second battery to either end of the first battery. Depending on which way the second battery is set, the ammeter indicates an electric current flowing through the wire or not.

Does a 9 volt battery light a light bulb?
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
What happens to a bulb when you move it to the battery on a circuit?
It doesn't matter where the bulb is in respect to the battery, as long as the circuit is complete, the bulb will light up.
What is the battery life of a 9 volt battery on a 3.5 volt of a bulb?
The battery life (assuming it is a primary cell) is determined by the Ampere-hour drawn from it. You cannot connect a 3.5V bulb directly to a 9V battery. The bulb will fuse.
If you connect a battery and a bulb in this way the bulb will not light?
yes
What makes a bulb brighter?
more battery's or a better bulb.
Headlamp bulb isn't bright?
Replace the battery and recharge if a rechargable battery if not it might need new bulb
