New In-Car Technology
People love gadgets that they can use in their everyday lives, none more so than those gadgets found in cars or that can be used in cars. Lets take a little peak at 3 gadgets that have either only just been launched or are set to go mainstream pretty soon.
Electronic Cigarette. There are a great deal of car drivers out there who like to smoke in their vehicle (it’s one of the only places left you are allowed to smoke). However, nobody likes the smell that is left behind in the car, not least any passages that you take. Not to mention the mess that the ash from the cigarettes makes. This new electronic cigarette solves all these problems by producing clean smoke that isn’t even harmful to the body. The best bit is you can recharge these gadgetsusing the cigarette lighter port, so it’ll save you a fortune.
Sound Blocking Head Rest. This is one of those gifts for men, when they are trying to concentrate on the task at hand. This new headrest addition emits low frequency sound waves that you can barely hear, but that intercept and block out all other noise in the car. This is bliss for any driver that suffers from nagging passengers, either in the seat next to them or the seats at the back.
Auto-Adjusting Car Seats. Not only does this technology help drivers be more comfortable, but also reduces their chances of being injured in a crash. Expected to be released by Ford in 2012, these new seats adjust automatically to your body shape and weight, giving you the best ergonomically friendly driving position. You can even program the seat to move to different positions depending on what style of driving you want to do. What is more, if the worst case scenario happens and you find yourself in a car accident, the seat will do it's best to protect you by moving itself into the safest possible position in a flash.If the seats behind the driver and front passenger seat are empty, the seats at the front of the car will move backwards and get lower down in the event of an impact, all in the space of a few milliseconds.
For the latest gifts aswell as superb Childrens Gifts and Rag Dolls which will be genuinley welcomed.
Physics Question involving Frequency: A car is parked 24.0 m directly south of a railroad crossing.?
A car is parked 24.0 m directly south of a railroad crossing. A train is approaching the crossing from the west, heading directly east at a speed of 59.0 m/s. The train sounds a short blast of its 269-Hz horn when it reaches a point 24.0 m west of the crossing. What frequency does the car's driver hear when the horn blast reaches the car? The speed of sound in air is 343 m/s. (Hint: Assume that only the component of the train's velocity that is directed towards the car affects the frequency heard by the driver.)
The component of the train's velocity directed toward the car is 59.0*cos(45) = 41.7m/s
so the freq heard fL is
fL = fS*(v/(v +vs)) = 269*(343/(343 -41.7)) = 306Hz
