Answer:
3.24m/s^2
Explanation:
The following data were obtained from the question:
U = 4m/s
V = 16m/s
t = 3.7secs
Acceleration is change in velocity with time i.e
a = (V — U) / t
a = (16 — 4) / 3.7
a = 12/3.7
a = 3.24m/s^2
The method which is appropriate for separating a mixture of iron and aluminum is A. using a magnet.
This is because aluminum does not have magnetic properties (thus it will be unaffected by the magnet), so it is easy to sort out all iron from the mixture using a magnet.
What? It would be nice if you show pic
Answer:
