Answer:
7.5x10-^8m
Explanation:
the formulae is v=fh ,where f is frequency
h is wavelength
hence wavelength=v/f
since the speed of light is 3x10^8
then the wavelength =3 x 10^8/4 x 10^15
=7.5x10^-8m
Answer:
D
Explanation:
Newtonian physics show that free fall is any motion of a body where gravity is the only force acting upon it. Hope this helps!
I reported this question by accident, I am sorry.
Anyways, there is no electric field at the center of a charged spherical conductor because all the charged particles are at the edges and because of the complete cancellation everywhere.
Particles in the solar nebula were more spread out at greater distances, so that accretion took longer and there was less time to pull in gas before the solar wind cleared the nebula.
