What is the relationship between wavelength and speed?
What is the relationship between wavelength and speed? Speed = Wavelength x Wave Frequency. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed. What is the longest […]
What is the difference between boron and silicon?
What is the difference between boron and silicon? Boron is exclusively found in the mineral fraction of bone. Silicon is distributed equally in the mineral and collagen fractions. Data suggest boron and silicon have different biological effects on bone. Silicon loading into bone mineral may be influenced by nutritional factors. What is boron used for? […]

How do you calculate the voltage after a resistor?
How do you calculate the voltage after a resistor? Ohm’s Law states that V=I*R, where V is voltage, I is current and R is resistance. In a series circuit, the voltage drop across each resistor will be directly proportional to the size of the resistor. In a parallel circuit, the voltage drop across each resistor […]
