The time of warming that occurs between ice ages is called the .

A) global climate
B) interglacial period
C) R-to-C ratio
D) reclamation
E) continental drift

B (I am not sure)

Explanation:

The cold periods are called glacials (ice covering) and the warm periods are called interglacials. There were at least 17 cycles between glacial and interglacial periods.

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
