Electric Motor The goal of this experiment is to build a simple electric motor and observe how it works. I will attempt to make it spin evenly by attaching it to a battery via jumper cables. The independent variable is the battery charge (1.5 V) and the dependent variable is how fast the motor spins. The lab doesn’t have multiple experiments for us to test this but I would hypothesize that the two variables would have a positive correlation: higher voltage‚ faster spin. I built my tiny motor

You rub balloons in your hair and then hang them like in the picture below. Explain why you think they move apart and what might affect how far apart they get. They move apart because they become charged while you are rubbing them in your hair and the charges are the same on both balloons. The more charges you get on the balloon

V=V (Ra + R1) 0.75A = (Ra + R2) 0.25A (Ra + R1) 3 = Ra + R2 3Ra + 3R1 = Ra + R2 2Ra = R2 – 3R1 Ra = 0.5(R2 – 3R1) 3. In a simple series circuit a battery is connected through an ammeter to an electric lamp. A voltmeter is connected parallel to the lamp. The ammeter reads 0.75 A and the voltmeter 50 V. What is the resistance of the lamp neglecting the current drawn by the voltmeter? If the current in the voltmeter is 0.001 A for each volt it indicates

Were there skateboarders or bikers? Or was there a combination of both? I think that skate parks should be only for skateboarders! Bikers should be banned from skateparks and go to a BMX park for the safety of themselves and others. Bikes and skateboards break if involved in a collision. People end up in the hospital because of being hit by bikers or their bikes. A lot of other skaters and I think bikers should be banned from skate parks. “Why?” you are probably wondering to yourself. Well there

Skateboarding is a multicultural sport that can be seen in many different ways. The skateboard can be used in different ways for example: • Recreational activity • Method of transportation • A job/ form of art. Skateboarding has been shaped and influenced by many skateboarders throughout the years. Created by California surfers in the 1950s. Skateboarding was a way to surf the concrete streets. The original designer of the skateboard is unknown as it seems to be that a multitude of people in fact came up with

Background: The Electric Motor Works (EMW) was Siemen’s primary producer of low wattage alternating current (A/C) motors‚ which sales volume was contributed by 80% of standard motors and 20% of customized motors. Although the firm had started to alter their program and had expanded the business in 1974‚ they still could not decline the price sufficiently to compete with the lower labour rate in Eastern Bloc competitors. Instead of mass production‚ EMW changed their strategy to manufacture efficiently

trends—and more and more like what it is: the essence of being human.” (382) SKATEBOARDING Skateboarding is a popular form of modern urban culture that is recognized worldwide. It has its own sense of art‚ music‚ and fashion. Originally‚ the skateboard was first developed around the 1930’s from children who were bored and searched for a better use of their old roller skates. Skateboarding did not become more recognized until about the late 1950’s by Californian surfers. Surfers saw “the movement

1990s‚ Longboards and Skateboards branched off into their respective disciplines. With the right setup‚ a longboard can give the feeling of surfing on hard smooth surfaces. There are a variety of riding styles: downhill‚ cruising and carving‚ slalom‚ dancing‚ freeriding‚ vert and sliding.[citation needed] A longboard generally can be as short or as long as the rider desires; the most popular range is about 36 to 60 inches. As well as being usually longer than a standard skateboard‚ longboards may also

It is important to first know exactly what skateboarding trucks are. Trucks are the visible t-shaped parts which mount on the underside of the deck and actually hold the wheels. Any skateboard would need a pair of trucks to be complete one for each pair of wheels. To know more details about the best skateboarding trucks‚ you could log on to the Internet and view pictures which will show you that trucks are not a single piece. They comprise of several parts which are the axle‚ hangar‚ kingpin‚ bushing
