Bike laws vary from state to state and from city to city. If someone is hurt in a bicycle accident, they should immediately contact an attorney who is familiar with the area …where the incident took place. Riding a bike can be a very pleasant and exhilarating experiences when all laws are followed and safety is the paramount concern. (MORE)

From the California Bicycle Helmet Statute West's Annotated California Codes; Vehicle Codes; Division 11. Rules of the road; Chapter 1. Obeidience to and effect of traffic law…s; Article 4. Operation of bicycles: (a) A person under 18 years of age shall not operate a bicycle, or ride upon a bicycle as a passenger, upon a street, bikeway, as defined in Section 890.4 of the Streets and Highways Code, or any other public bicycle path or trail unless that person is wearing a properly fitted and fastened bicycle helmet that meets the standards of the American National Standards Institute (ANSI Z 90.4 bicycle helmet standard), the Snell Memorial Foundation's Standard for Protective Headgear for Use in Bicycling, or the American Society for Testing Materials (ASTM F-1447 standard). This requirement also applies to a person who rides upon a bicycle while in a restraining seat that is attached to the bicycle or in a trailer towed by the bicycle. (MORE)

A bicycle provides a method of human powered transportation so a person can travel on wheels. The person must learn to balance on the device, steer, and work the pedals. It ha…s two wheels, a front wheel and a rear wheel. The pedals are connected by a chain to the rear wheel. When the rider works the pedals with his feet, the rear wheel goes around. It pushes against the pavement which makes the bicycle go forward. The wheels also have a fairly large diameter, an important feature. That enables them to work as gyroscopes. Like any other gyroscope, as long as they are in motion, they tend to remain in the same plane. That helps keep the bicycle upright. Thus, a bicycle in motion does not tend to fall over. The size of the wheels have been determined by experiments over the years. Larger wheels would make the bicycle more stable but would make the bicycle harder to push. Smaller wheels would be less expensive but would make the bicycle less stable. (MORE)

This law was first discovered by Charles Augustin de Coulomb. It explains that all magnetic objects have the tendency to repel or attract to one another. Like charges repel on…e another and unlike charges attract one another. The attraction or repulsion occurs in a straight line, there is a force between the charges and the bigger the charges the greater the force. (MORE)

Ohm's Law only has to do with electronics. Ohm's Law is considered one of the key function in electronics because it gives the quantitative relationship between the three …important concepts of V=voltage, I=current, and R=resistance. Another Answer Ohm's Law is a law of constant proportionality. It ONLY applies to those conductors and other components whose ratio of voltage to current remains constant for variations in voltage. It does not apply to conductors or components whose ratio of voltage to current changes for variations in voltage. So Ohm's Law is not a universal law. Conductors and other devices which obey Ohm's Law are termed 'linear' or 'ohmic'; those that do not (the majority, in fact!) are termed 'non-linear' or 'non-ohmic'. Some, but not all metals, are linear (e.g. tungsten is not) and most electronic components such as diodes, electrolytes, and gases are non-linear. The ratio of voltage to current is, of course, resistance. And we can use this ratio to determine what the resistance of a device happens to be for that particular ratio, at any given voltage, even for devices that do not obey Ohm's Law. For non-linear devices, the ratio continuously changes for variations in voltage. So, it's questionably whether Ohm's Law should be 'law' at all, and one might wonder why we even bother to teach it! It is quite incorrect to define Ohm's Law as, "resistance equals voltage divided by current", as this equation is derived from the definition of the ohm, and NOT from Ohm's Law -which makes absolutely no reference to resistance.

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4

more people will wear helmets, hence less people will die from falling off bikes and splitting their skulls open and letting their brains fall out.

First of all, 'electricity', is the name given to a branch of science; it is NOT a quantity that can be measured, such as voltage, current, etc. Secondly, Ohm's Law …does NOT 'affect electricity'. It's the other way around! It merely describes how 'electricity' behaves; it doesn't determine how 'electricity' behaves! Thirdly, Ohm's Law is not a universal law, and only applies to very few materials or electrical components. In fact, it could be argued that Ohm's Law isn't a 'law' at all because it applies in so few circumstances. Ohm's Law states that the current passing through a conductor is proportional to the potential difference appearing across that conductor... providing various physical conditions, such as temperature, remain constant. But, unfortunately, this is not true in most practical circumstances. Frequently, too, Ohm's Law is credited with the equation, R = U/I; again, this is not the case, because this equation is derived from the definition of the ohm, not from Ohm's Law. There is a really serious case for scrapping Ohm's Law altogether! (MORE)
