Answer:
0.5 m/s2
Explanation:
accelration formula : final velocty - starting velocity divided by time
Answer:
Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation).

Gamma rays ..........................
Answer:
40 m/s due north
Explanation:
Consider that the south direction a negative Y axis and north direction as + Y axis
v1 = 20 m/s South = 20 (-j) m/s
v2 = 20 m/s North = 20 j m/s
Change in velocity = v2 - v1 = 20 j - 20 (-j) = 40 j m/s
So, change in velocity is 40 m/s due north.
