How do you tell the difference between independent and dependent variables? The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected. […]
How many galaxies have we named?
How many galaxies have we named? All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com. What are the 4 types of galaxies? In 1936, Hubble debuted a way to […]
What is the force of static friction equal to?
What is the difference between a screw and a wedge?
What is the difference between a screw and a wedge? A wedge is much bigger than any normal screw. Wedge has a plain surface but screw has a surface with ridges and grooves. • Wedge is typically used for cutting and slicing purposes but screw is typically used for fixing and attaching purposes. Is screw […]
What are the 5 examples of sedimentary rocks?
What are the 5 examples of sedimentary rocks? Examples include: breccia, conglomerate, sandstone, siltstone, and shale. Chemical sedimentary rocks form when dissolved materials preciptate from solution. Examples include: chert, some dolomites, flint, iron ore, limestones, and rock salt. What are the 3 main types of sedimentary rocks? There are three different types of sedimentary rocks: […]
What are the 2 main properties of sound?
What are the 2 main properties of sound? The two main properties of sound are frequency and amplitude. The frequency of the sound waves determines the pitch of the sound. The amplitude of sound determines the loudness. The quality of sound is affected by the pitch and the loudness. What is sound and its properties? […]
What are six steps of the scientific method?
What are six steps of the scientific method? The scientific method consists of six steps: Define purpose. Construct hypothesis. Test the hypothesis and collect data. Analyze data. Draw conclusion. Communicate results. Which of the following lists the scientific method in the correct order? There are four basic steps involved with the scientific method. The usual […]
What is the standard form of 12000000000?
What is the standard form of 12000000000? The standard form is: 1.2 * 10^10. What is the exponential form of 648? Answer. ANS: 2×2×2×3×3×3×3 =2^3 × 3^4… How the distance to stars is measured? To measure the distance of a star, astronomers use a baseline of 1 astronomical unit (AU), which is the average distance […]
Which mineral properties can you identify without special tools?
Which mineral properties can you identify without special tools? In working with hand samples without specialized tools, mineral hardness is specified by the Mohs hardness scale. The Mohs hardness scale is based 10 reference minerals, from talc the softest (Mohs hardness of 1), to diamond the hardest (Mohs hardness of 10). It is a relative, […]
How do you calculate channel capacity when SNR is present?
How do you calculate channel capacity when SNR is present? Hence, the channel capacity is directly proportional to the power of the signal, as SNR = (Power of signal) / (power of noise). so for example a signal-to-noise ratio of 1000 is commonly expressed as: 10 * log10(1000) = 30 dB. What is channel capacity? […]
