Which light bulbs burn brighter in series or parallel? Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit. Does power remain same in series? In a series circuit the current is the same at any particular point […]

How can you tell a rock is igneous? Igneous rock is created by volcanic activity, forming from magma and lava as they cool and harden. It is most often black, gray, or white, and often has a baked appearance. Igneous rock may form crystalline structures as it cools, giving it a granular appearance; if no […]

Why is i the square root of negative one? Here, the term “imaginary” is used because there is no real number having a negative square. There are two complex square roots of −1, namely i and −i, just as there are two complex square roots of every real number other than zero (which has one […]

Does time stop at absolute zero? 1 Answer. You are confusing time with the flow of time. But even if you take the conventional view of the flow of time, motion does not stop at absolute zero. This is because quantum systems exhibit zero point energy, so their energy remains non-zero even when the temperature […]

What are silicate minerals made of? A silicate mineral is generally an ionic compound whose anions consist predominantly of silicon and oxygen atoms. In most minerals in the Earth’s crust, each silicon atom is the center of an ideal tetrahedron, whose corners are four oxygen atoms covalently bound to it. What are the 5 subclasses […]

Is banana a complex carb? By contrast, a banana has a complex structure made up of water, fat, protein, fiber and myriad other molecules, as well as carbohydrates in the form of simple sugars and starches. This complex structure is called a food matrix. Does Fiber cancel sugar? Fiber is a type of carbohydrate that […]

Is contour plowing good? Contour farming can reduce soil erosion by as much as 50 percent compared to up and down hill farming. By reducing sediment and runoff and increasing water infiltration, contouring promotes better water quality. Can you farm on hills? For planting: consider “contour farming” When planting on a steel hill or uneven […]

What does spoke in the wheel mean? : TO PUT A SPOKE IN ONE’S WHEEL — “When you are not in accord with another person’s plans or projects, you ‘put a spoke in his wheel’ by taking some action that will interfere with or impede his progress. … Is it OK to ride a bike […]

Can virus be considered living? So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than […]

How many days does it take to form a zygote? The cells of the zygote divide repeatedly as it moves along the fallopian tube and the zygote takes between 3 and 5 days to enter the uterus. Once inside the uterus, cell division continues and eventually forms a hollow ball of cells referred to as […]
