Does a car burn more gasoline when its lights are turned on?

Turning on the lights of a car will increase the electrical load on the battery, but it will not significantly impact the fuel consumption or gas mileage of the vehicle. The amount of gasoline burned by the engine is not directly affected by the operation of the lights.


How do you turn the dome lights the lights underneath the dash when they don't go off after getting out of the car?

If the dome lights or lights under the dash don't turn off after exiting the car, you can try closing all doors properly and ensuring the parking brake is engaged. If they still do not turn off, there may be a faulty door switch or wiring issue that needs to be addressed by a mechanic. You can also try manually turning off the lights using the light switch if applicable.


How is energy turned to mass What is an example of turning energy to mass?

Energy can be turned into mass through the process of pair production, where a high-energy photon creates a particle-antiparticle pair. An example of turning energy into mass is when a gamma-ray photon interacts with an atomic nucleus, leading to the production of an electron-positron pair.


Can leaving lights on only in the rooms you are moving between save energy?

Of course not. When the light is on, it uses energy; when it is off, it doesn't, 'tis as simple as that. I have heard certain rumors that turning it on will use (for example) the equivalent of two hours of just being normally on. Since turning the light on takes but a few seconds, a simple calculation shows that this would produce enough current to trip any standard fuse or circuit-breaker. What's more, I personally turned a one of those lights (40 Watts) on and off 40 times in a row, and checked the energy usage. According to the above mentioned rumor, this would have to use about 2 kWh; the meter didn't advance a single kWh. Unfortunately, I don't have the equipment to do finer measurements, but it just doesn't make sense.


Does a tv use more power if it's left on for an hour or if it's turned off and then back on?

A TV typically uses more power if it's left on for an hour than if it's turned off and then back on. When a TV is on, it is actively using electricity to display images and produce sound. Turning it off reduces power consumption, but the initial surge of power when turning it back on should be considered.

Why lights in a house often dim when a motor like washing machine is turned on?

Simply because of the extra drain on the circuit. When a high-current device like a washing machine is switched on - it creates a temporary 'dip' in the power supply around the building. The mains supply compensates for the extra load on the circuit fairly quickly - but it's still noticeable by the dim lights.
