The elementary unit of charge (the charge on one electron) = 1.6 x 10^-19 coulomb.
1 coulomb = the charge on 6.25 x 10^18 electrons
10 coulombs = the charge on 6.25 x 10^19 electrons
Answer: WaveSpeed = Wavelength x Frequency
Explanation: Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation. This equation can be used to calculate wave speed when wavelength and frequency are known.
Without friction, Newton's second law, in the form F=ma would apply.100=50a. So the acceleration should be 2m/s^2100-friction = 50x1.5100-friction = 75100-75=friction25N = friction
It would be B because it makes science to the topic
