Answer:
a) 
b) 
c) 
Explanation:
a) The speed of a wave is given by the following equation:
Where:
λ is the wavelength
f is the frequency
b) The harmonic wave has the following equation:
A is the amplitude (2 m)
k is the wavenumber (2π/λ)
ω is the angular frequency (2πf)
c) Here we need to find the heigth at x=3 m and t =10 s, so we need to find y(3,10).
I hope it helps you!
Answer:
40,000
Explanation:
Momentum is defined as mass*velocity, so a doubling of velocity means a doubling of momentum
It is important to note that the electromagnetic spectrum has a variety of wavelength and frequency of light in it. Some lights we can see, while others are not visual to our naked eye. It is actually very important to determine the kind of light as different lights have different wavelengths and frequencies. some lights are of very high frequency like the gamma rays, while others are of far lower frequency. <span />
Answer:
Lose electrons
Explanation:
When a positively charged conductor touches a neutral conductor, the neutral conductor will lose electrons. Only electrons can move from one conductor to another, so if the neutral conductor ended up with a positive charge it means it lost electrons. The conductor touching and the neutral conductor both end up being charged positively.
