How many beats are in a rest? 4 beats Is 4/8 a simple or compound? 4/2 and 4/8 are also simple quadruple. Notice that a time signature in simple meter will always have a 2, 3, or 4 for the top number. While beats in simple meter are divided into two notes, beats in compound […]

What are 2 features that all forms of matter have? All matter has physical and chemical properties. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space occupied by a sample). What is a special property? : a […]

Who has the right away at a green light? If the driver in the car turning right has a green light at the same time as you when you attempt to make a left, then you, in the car turning left, must yield the right of away to the right turning driver. Can you turn […]

What is another name for a decomposition reaction? Decomposition reactions are also known as analysis reactions or chemical breakdowns. The opposite of this type of reaction is a synthesis, in which simpler reactants combine to form a more complex product. How can a displacement reaction be recognized? Recognizing a Single-Displacement Reaction Usually, when two compounds […]

How is communication possible without a physical medium? An unguided transmission transmits the electromagnetic waves without using any physical medium. Therefore it is also known as wireless transmission. In unguided media, air is the media through which the electromagnetic energy can flow easily. What is the role of transmission medium in a network? Transmission media […]

What direction do surface winds move in the Northern Hemisphere? The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. The Coriolis effect causes some winds to travel along the edges of the high-pressure and low-pressure systems. Why is Coriolis effect different in Southern Hemisphere? The reverse […]

What is a good U-value? The best insulating materials have a U-value of close to zero – the lower the better. Building regulations currently stipulate that for a new building, the elements must have maximum U-values as follows: Wall – 0.3 W/m2k. Roof – 0.15 W/m2k. What is a good window U-value? In a cold […]
