B refraction in the case of optical microscopes (ie not, say, electron microscopes) in which lenses are used to refract light and form the images, some of which you see.

A boy pulls with a 20 N force, at a 20 degree incline. What part of the force moves the wagon?

nalin [4]

Answer:

horizontal direction force move wagon at 18.79 N

Explanation:

given data

force F = 20 N

angle = 20 degree

to find out

What part of the force moves the wagon

solution

we know here as per attach figure

boy pull a wagon at force 20 N at angle 20 degree

so there are 2 component

x in horizontal direction i.e F cos20

and y in vertical direction i.e F sin20

so we can say

horizontal direction force is move the wagon that is

horizontal direction force = F cos 20

horizontal direction force = 20× cos20

horizontal direction force = 18.79 N

so horizontal direction force move wagon at 18.79 N

A neutral atom possesses an atomic number of 13 and an atomic mass of 27. Three electrons are lost. From what region of the atom

slega [8]

The atomic number of the atom is 13. This means that its electronic configuration is (2 8 3) or in other words:
1s2, 2s2, 2p6, 3s2, 3p1

If three electrons are lost, then these electrons are removed from the outermost level.
In our case, electrons are removed from the third energy level (one electron is removed from the 3p orbital and two electrons are removed from the 3s orbital).
