What would the velocity of an object be if it was on a 1.75m
JulijaS [17]

Answer:

T = 4 sec / 2 = 2 sec      period of revolution

S = 2 pi R = 2 * pi * 1.75 m = 11 m

V = S / T = 11 m / 2 sec = 5.5 m/s       speed of object

The magnetic field in a plane monochromatic electromagnetic wave with wavelength λ = 598 nm, propagating in a vacuum in the z-di
Oksanka [162]

Answer:

For this given plane monochromatic electromagnetic wave with wavelength λ=598 nm, the wavenumber is k=0,0105\ x\ 10^{-9}\ m^{-1} .

Explanation:

For a plane electromagnetic wave we have that the electrical and magnetic field are:

E(r,t)=E_{0}\ cos ( wt-kr)\\\ B(r,t)=B_{0}\ cos(wt-kr)

In this case we have the data for the magnetic field. We are told that the magnetic field in a plane electromagnetic wave with wavelength λ=598 nm, propagating in a vacuum in the z direction (\hat k) is described by

         B=8.7\ x\ 10^{-6}\ T sin(kz-wt) (\hat i+\hat j)

(\hat i,\hat j, \hat k are the unit vectors in the x,y,z directions respectively)

The wavenumber k is a measure of the spatial frequency of the wave, is defined as the number of radians per unit distance:

          k=\frac{2\pi}{\lambda}

where λ is the wavelength

So we get that

k=\frac{2\pi}{\lambda} \rightarrow k=\frac{2\pi}{598 nm}  \rightarrow k=0,0105\ x\ 10^{9}\ m^{-1}

The wavenumber is

            k=0,0105\ x\ 10^{9}\ m^{-1} .
