How can you determine the direction of field lines? A magnetic field line is the path along which a free north-pole tends to move. The direction of a magnetic field at a point is determined by placing a small compass needle. The N – pole of compass indicates the direction of magnetic field at that […]

What is 0.78 rounded to the nearest tenth? Round 0.78 to the nearest tenth. First, divide a number line in to tenths and look at the position of 0.78. Then, determine whether 0.7 is closer to 0.7 or 0.8. The answer is that 0.8 is the nearest tenth. What is 0.09 rounded to the nearest […]

Does an experiment need a control group? An experiment may include multiple experimental groups at one time. A control group is a group separated from the rest of the experiment such that the independent variable being tested cannot influence the results. While all experiments have an experimental group, not all experiments require a control group. […]

What are the 10 processing devices? Processing device examples Central processing unit (CPU) Graphics processing unit (GPU) Motherboard. Network card. Sound card. Video card. What is an example of processing? The definition of a process is the actions happening while something is happening or being done. An example of process is the steps taken by […]

How is power calculated? Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). One horsepower is the amount of […]

What are the 4 biotic factors in an ecosystem? Biotic and abiotic factors Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals. What is the role of producers in most ecosystems? As producers are the first level in a food system, they […]

Even your school, attached to Earth, is moving through space. When an object moves from one location to another, it […]

How do you find the refractive index of oil? The refractive index of essential oils can easily be measured with an Abbemat refractometer. It can thus provide insight as to their quality. Does oil have the same refractive index as glass? You see a glass object because it both reflects and refracts light. When light […]
