As we know by Gauss's law that
so for line charge the gaussian surface is cylindrical in shape
so we will have
now by rearranging the terms
so here we will have to find the x component of electric field so it is given by above equation
here x = distance from the wire where we need to find electric field
Answer:
Explanation:
Snell's law for index of refraction of a medium is as follows .
sin i / sin r = μ
i is angle of incidence , r is angle of refraction and μ is refractive index.
sin r = sin i / μ .
As μ for blue light is greatest , angle of refraction for blue light will be least . Similarly , angle of refraction will be maximum for red light .
So maximum deviation in the direction of light will occur in blue light due to least angle of refraction because
deviation angle = angle of incidence - angle of refraction .
So the order of light from inward towards surface
= blue , green , red .
Answer:
it is impossible for all creatures to become the same species.
Explanation:
According the exercise:
blancmange=36
halo-halo=37
mouses=38
if one blancmange and one halo-halo have contact with each other, I will have:
blancmange=36-1=35
halo-halo=37-1=36
mouses=38+2=40
if you want to keep the population of mice on the rise, this proportion must continue, therefore:
blancmange=36-36=0
halo-halo=37-36=1
mouses=38+36+36=110
The maximum amount of mouses is 110. According to these data, it is impossible for all creatures to become the same species.
Yes a twig will float on water
1 g/cm³- density of water
roughly 0.50–0.75 g cm-3-density of twig
because a twig is less dense than water the twig will float
Answer:
318K
113°F
Explanation:
45°C = 45 + 273K = 318K
45°C = (45 × 9/5) + 32 = 81 + 32 = 113°F
