The hunter walks north 8 km and then 3km south. find the displacement

5 km North

Explanation:

Displacement refers to the distance covered in a specific direction.

In this case,

Distance covered due north = 8 km

Distance covered due south = 3 km

Therefore;

If we take the distance towards north to be +8 km

The distance towards south to be - 3 km

Then;

Displacement = +8km + (-3km)

                      = + 5km

                       = 5 km North

Therefore;

The displacement is 5km towards North.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
