What are the rules for current in series and parallel circuits? Chapter 5 – Series And Parallel Circuits Voltage: Voltage is equal across all components in a parallel circuit. Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather […]

What is a disadvantage of asexual reproduction? The disadvantage of asexual reproduction is that organisms do not receive a mix of traits from both parents. An organism that is born through asexual reproduction only has the DNA from the one parent. In fact, the offspring is genetically an exact copy of the parent. What are […]

Do 2 of the same elements make a compound? A compound is a unique substance that forms when two or more elements combine chemically. A compound always consists of the same elements in the same ratio. If the same elements combine in different ratios, they form different compounds. Types of compounds include covalent and ionic […]

Can you hack radio frequency? In fact, some hackers are even capable of using radio signals to hack into an unconnected device and steal confidential corporate data. Researchers in Israel have developed a technology that extracts information from a machine using radio frequencies and wireless communications. What are the basics of radio? Radio waves are […]

How do you nail in tight space? When working with small nails or in tight quarters (or both!) keep your fingers out of the line of fire with the help of a hair accessory. A bobby pin is perfect because it can grip even the smallest nails and it provides plenty of distance between your […]

How much money does it cost to build a nuke? Nuke construction: $111.3 million for the first, $9.95 million for each thereafter. ICBM construction: $200 million in research and development, $40 million per missile (optimistic) Supporting facility construction: $15 million. Land acquisition: $416,000 to $1.2 million. How much did the US spend on the atomic […]

How many times does current change in one second? In public power distribution systems in the United States, (including household current), the voltage reverses itself 60 times per second. In some countries, the voltage reverses itself 50 times per second. The rate at which alternating current reverses direction is called its frequency, expressed in hertz. […]

What is a maximum load moment? Load Handling And Composition On A Forklift – Part III: Maximum Load Moment. The pivot point on a sit-down counterbalanced forklift is the axle of the front wheels. It is this Load Moment that determines how much overturning force is being applied to the forklift (Load moment = Weight […]

Is RX7 faster than RX8? RX7 is alot faster than RX8, my friend has one. Both cars have bad fuel economy and drinks oil. In the RX7 I understand why it has bad mpg and drinks oil, but in the RX8 I really really dont understand why the mpg is so low in a pretty […]

What are the two classes of matter? Classifying Matter Matter can be classified into several categories. Two broad categories are mixtures and pure substances. A pure substance has a constant composition. All specimens of a pure substance have exactly the same makeup and properties. What group of mixtures can be separated by handpicking? Answer Expert […]
