Which of the following types of agriculture is NOT traditionally practiced in tropical climate zones? Grain
Intensive subsistence
Mixed crop and livestock
Plantation
Shifting cultivation

Grain

Explanation:

Grain is not traditionally grown in areas with a tropical climate as they are more used to areas with all four seasons and tropical areas usually have two.

This is why grain preferred to grow in areas like the northern United States, southern Canada, and Eastern Europe where the four seasons are very clearly seen.

ek = (m·v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) ·v2/2

ek = (200 + 250) ·2,32/2 = 450·5,29/2 = 1190,25 j
