Answer:

P = 3800 W

Explanation:

Power is equal to energy divide by time P = E/t

plug in 4560000 J for energy

convert 20 minutes to seconds

20 * 60 = 1200 seconds

plug in 1200 seconds for time

P = 4560000/1200

P = 3800 W

Helium–neon laser light (λ = 632.8 nm) is sent through a 0.350-mm-wide single slit. What is the width of the central maximum on
Cloud [144]

Answer:

The width of the central bright fringe is 7.24 mm.

Explanation:

Given that,

Wavelength = 632.8 nm

Width d= 0.350 mm

Distance between screen and slit D= 2.00 m

We need to calculate the distance

Using formula of distance

y_{m}=\dfrac{\lambda D}{d}

Put the value into the formula

y_{m}=\dfrac{632.8\times10^{-9}\times2.00}{0.350\times10^{-3}}

y_{m}=3.62\ mm

We need to calculate the width of the central bright fringe

Using formula of width

width = 2\times|y_{m}|

Put the value into the formula

width=2\times3.62

width = 7.24\ mm

Hence, The width of the central bright fringe is 7.24 mm.

Does energy have mass and take up space?
Katarina [22]
Energy does not have a mass to take up space... because........let's say you shine a light into space the volume of the light beam is zero... And say you shine a torch by a black hole what would happen is gravity would pull the light due to gravity...so NO energy does not have have a mass and take up space....hope it helped
