K is cation by losing of electron whereas Br is anion due to accepting of electrons.
<h3 /><h3>Is charge appears when an atom lose or accept electron?</h3>
Yes, the positive ion appears on K and become cation whereas the negative ion bears on Br which make it anion because of losing and gaining of electron by these atoms. This transferring of electrons leads to formation of ionic bonds between them.
So we can conclude that K is cation by losing of electron whereas Br is anion due to accepting of electrons.

Answer:
R
Explanation:
Her distance from home and Time increase
the stops when she gets to the library
then her distance from home decreases while her time increases
work done by gravitational force = mass × g × height
= mgh
= 5 × 10 × 8 N
<h3>= 400 N</h3>
Momentum = mass x velocity
= 1500 x 8
= 12000 kg m/s
In a collision an object experiences a force for a specific amount of time, which results in a change momentum(the objects mass may ethier speed up or slow down). Impulse will be produced because of force appiled to an object over a period of time.
