Answer:
106.83
Explanation:
N = 332, l = 14 cm = 0.14 m, i = 0.88 A, B = 0.28 T
Let ur be the relative permeability
B = u0 x ur x n x i
0.28 = 4 x 3.14 x 10^-7 x ur x 332 x 0.88 / 0.14 ( n = N / l)
ur = 106.83
Alexandria became the center for Hellenistic scholarship and culture. It was a great revolution in learning during this era as Alexandria had a library filled with books and important documents which were copied and even stolen. Over 500,000 titles were present in Alexandria's library.
Explanation:
Whenever an object is at its highest point, the velocity and acceleration of the object is zero.
The relationship between the frequency and wavelength of a wave is given by the equation:
v=λf, where v is the velocity of the wave, λ is the wavelength and f is the frequency.
If we divide the equation by f we get:
λ=v/f
From here we see that the wavelength and frequency are inversely proportional. So as the frequency increases the wavelength decreases.
So the second statement is true: As the frequency of a wave increases, the shorter the wavelength is.
