I think it might be D or B
And my other two might be A or C
I think this is what you wanted, so good luck!
Answer:
infrared for longer and ultraviolet for shorter
Explanation:
let me now if right
Answer: -2m/s2
Explanation:
Using the following equation ; acceleration = Change in velocity / time
i.e a = v - u / t
where 'a' = acceleration
v = final velocity
u = initial velocity
t = time
Therefore; from the graph we have acceleration to be, 0 - 6m/s / 3s = -2m/s2
