An industrial laser is used to burn a hole through a piece of metal. The average intensity of the light is = 2.93 × 109 W/m2. Wh

To solve this problem, it is necessary to apply the concepts related to the electric field according to the intensity of the wave, the permittivity constant in free space and the speed of light.

As well as the expression of the rms of the magnetic field as a function of the electric field and the speed of light.

PART A) The expression for the rms of electric field is

$E_{rms} = \sqrt{\frac{S}{\epsilon_0 c}}$

Where,

S= Intensity of the wave

$\epsilon_0$ = Permitivitty at free space

c = Light speed

Replacing we have that,

$E_{rms} = \sqrt{\frac{(2.93*10^9)}{(8.85*10^{-12})(3*10^8)}}$

$E_{rms} = 1.05*10^6N/C$

The RMS value of electric field is $1.05*10^6N/C$

PART B) The expression for the RMS of magnetic field is,

$B_{rms} = \frac{E_{rms}}{c}\\B_{rms} = \frac{1.05*10^6}{3*10^8}\\B_{rms} =3.5*10^{-3}T$

The RMS of the magnetic field is $3.5*10^{-3}T$

When driving on slick roads, why is it advisable to apply the brakes slowly?

ValentinkaMS [17]

When you step on the brakes you activate the pads that touch your tyres and slow you down with friction. If you are driving through rain a small layer of water will develop inbetween the tyre and break pad. This will cause your vehicle to hydroplane and loose control of your vehicle. If you apply the vehicles brakes slowly this reduces the chances of the vehicle loosing control due to the hydro planing not being present. It is also advisable to let go of the gas in heavy rain rather than braking. Hope this helps!

In a double-slit experiment, the third-order maximum for light of wavelength 520 nm is located 17 mm from the central bright spo

Vera_Pavlovna [14]

Answer:

The distance from the central bright spot is 13.73 mm.

Explanation:

Given that,

Wavelength = 520 nm

Width d= 17 mm

Distance L= 1.6 m

Order = 3
