Answer:
it will give one electron to the bromine atom, so the bromine atom will have 36 electrons. this is an ionic bonding
Explanation:
To solve this problem we will apply the concepts related to the electric field, linear charge density and electrostatic force.
The electric field is

Here,
= Linear charge density
= Permittivity of free space
r = Distance
The linear charge density can be written as,
Linear charge density is given as

Replacing,


The initial and final electric Force can be written as function of the charge and the electric field as


If we replace the value for the electric field we have,

Length is one third at the end, then

The ratio of the force is


Therefore the required ratio is 3
Answer:
15.76°
Explanation:
Hi!
Let C~ = A~ + B~
Then
C~ dot A~ = |C| |A| cos Ф
C~ dot A~ = (A~ + B~) dot A~ = |A|^2 + |B| |A| cos(120)
Therefore
cos Ф = (|A| + |B| cos(120)) / |C| = 15.65/|C|
and
|C|^2 = |A|^2 + |B|^2 + 2 |B| |A| cos(120)
|C| = 16.261
cos Ф = 15.65/16.261
Ф = 15.76°
Answer:

Explanation:
The gravitational potential energy gets transformed into translational and rotational kinetic energy, so we can write
. Since
(the ball rolls without slipping) and for a solid sphere
, we have:

So our translational speed will be:
