What should I learn to draw first? The first thing that most drawing tutorials teach you to draw is shapes, starting with a sphere. After all, any object that you see around you can be constructed by using one, or a combination of, three different shapes: A circle – a sphere is a circle in […]
How do you tell the difference between independent and dependent variables?
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. […]
Is there any time lag between action and reaction?
Is there any time lag between action and reaction? 1 Answer. At any instant in time the action and reaction forces are equal – but since as Sofia pointed out they act on different bodies, that doesn’t mean they “cancel out”: each of the bodies experiences one of the forces and accelerates accordingly. How is […]
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, […]
What has 7 protons and 9 Neutrons?
What has 7 protons and 9 Neutrons? Fluorine Which is heavier neutron or proton? High on this list are the masses of subatomic particles. Dozens of particles are known to physicists, but the most familiar are the constituents of atoms: electrons, protons and neutrons. The neutron is very slightly heavier than the proton, by about […]
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? […]

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? […]
