clashes between air masses can cause extreme variation in temperature. In the United States which types appear to be most affected by air masses and why ?

don't guess, because if you answer incorrectly, points are taken off. even if you don't finish, take your time. to study, use the sample questions. there is not much preparation to take the pre- tests.

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
