What is the formula of circuit? The total resistance in a series circuit is equal to the sum of the individual resistances: RTotal = R1 + R2 + . . . R. Total voltage in a series circuit is equal to the sum of the individual voltage drops ETotal = E1 + E2 + . […]

What are the 3 major types of magma? There are three basic types of magma: basaltic, andesitic, and rhyolitic, each of which has a different mineral composition. All types of magma have a significant percentage of silicon dioxide. Basaltic magma is high in iron, magnesium, and calcium but low in potassium and sodium. Which type […]

Is sin 90 degrees undefined? The exact value of sin 90 degrees is equal to 1. What if Tan is undefined? tan(θ) will be undefined when x = 0, since you would be dividing by zero. This places you at an angle of either 90º or 270º. Is Tan 0 undefined? Trigonometric functions are equal […]

What are examples of analog technology? Examples of analog technology: photocopiers. old land-line telephones. audio tapes. old televisions (intensity and color information per scan line) VCRs (same as TV) Which is more reliable analog or digital? Analog signals are composed of continuous waves that can have any values for frequency and amplitude. Digital signals are […]

Which of these is a consequence of speeding less wear on brakes? When a car is speeding, the ability of the car to make sharp bends is decreased because the time required to negotiate the bend is reduced. When at high speed, the brakes can easily fail due to high wear and tear on the […]

What happens if you hold 1 on a microwave? Often, pressing and holding 1, 0, Stop or Cancel will either result in turning off the beeping sounds or activating a child lock feature. Can a person be microwaved? A Human Being in a Microwave Well, no matter what, it wouldn’t be a pleasant experience. But […]

What are the impacts of extinction? They may carry disease, prey on native species, and disrupt food webs. Often, they can out-compete native species because they lack local predators. An example is described in Figure below. Over-harvesting of fish, trees, and other organisms. Why is biodiversity in danger? Habitat loss from exploitation of resources, agricultural […]

Which out of the following is not an intensive property? Volume is not an intensive property. Is pressure an intensive property? 1 Answer. You are right that intensive properties are not additive like the properties which depend on the extent of the system. Pressure is indeed an intensive property because it is force divided by […]

Where do you look for blind spots? Blind spots are the areas to the sides of your car that can’t be seen in your rear mirror or side mirrors- to make sure these spots are clear before changing lanes, you’ll have to physically turn around and look to see what kind of crazy stuff is […]
