Are beverages usually acidic or basic? why is this?

ACIDIC

Explanation:

Usually beverages contain carbonated water. Carbonated water is the water containing dissolved carbon dioxide gas.

The carbon dioxide gas (CO₂) when dissolved in water produces carbonic acid (H₂CO₃), which makes the drinks acidic in nature.

H₂O(l) + CO₂(g) → H₂CO₃(aq)

This makes the pH of the drinks around 3 - 4.

Therefore, the beverages are usually acidic and not basic.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
