Which of the following is not a reason to choose a community college? A. Relaxed admission requirements B. No admission requirements C. Smaller student-to-teacher ratios D. Lower tuition rates

I believe the answer is (B).

Clearly (C) and (D) are positive things so they definitely can't be the answer. This leaves us with (A) and (B). Once again (A) is a positive thing so the answer should be (B).

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

the answer is c teaching students and collaborating with teachers on instructional content.
