What happens to the composition of an atom to cause it to become positively or negatively charged?

1 answer:

5 0

An atom is neutral when the number protons and electrons are equal, so when either of these two are taken away or added it will change the charge of an atom. If protons are added or electrons are taken away, a once neutral object will be positive. But if protons are taken away or electrons are added to a once neutral atom, the charge will become negative. Usually electrons are the ones that move and change the atoms charge.

<h3>Ⲋⲟⳑⳙⲧⳕⲟⲛ :</h3>

We are given that a cylinder shaped bucket is used as a sand container . We have to find how much sand it can hold , which can be found by knowing the volume of cylindrical bucket .The volume of a cylinder is given by :

$\quad\dashrightarrow\quad {\pmb{\sf {Volume = \pi r^2 h }}}$

where,

π = 3.14
r = 0.5 feet
h = 2.5 feet

$\quad\dashrightarrow\quad \sf {V =\pi r^2 h }$

$\quad\dashrightarrow\quad \sf { V = 3.14 \times 0.5^2 \times 2.5}$

$\quad\dashrightarrow\quad \sf {V = 3.14\times 0.5\times 0.5\times 2.5 }$

$\quad\dashrightarrow\quad \sf {V = 1.9625 }$

‎ㅤ‎ㅤ‎ㅤ‎ㅤ‎ㅤ~Hence, the bucket can hold 1.96 feet³ of sand!

$\rule{350pt}{2pt}$

How can a parasite utilize multiple hosts

erica [24]

Parasites that use only a single host species in their life are called monoxenic; those with multiple hosts are called heteroxenic. ... intermediate hosts are all the others. Paratenic hosts are hosts that are used only for transport; no life cycle stages are completed within the host.
