Adischarge lamp rated at 25 w (1 w = 1 j/s) emits yellow light of wavelength 580 nm. how many photons of yellow light does the lamp generate in 1.0 s?

the number of photons of yellow light does the lamp generate in 1.0 s is 7 x

Explanation:

given information:

power, P = 25 W

wavelength. λ - 580 nm = 5.80 x m

time, t = 1 s

to calculate the number of photon(N), we use the following equation

N = λPt/hc

where

λ = wavelength (m)

P = power (W)

t = time interval (s)

h = Planck's constant (6.23 x Js)

c = light's velocity (3 x )

So,

N = λPt/hc

   = (5.80 x )(25)(1)/(6.23 x )(3 x )

    = 7 x

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
