They are toxic and all non metals
Answer:
C
Explanation:
From above question we know that
A = 6.2 m
f = 1.6 rad/s
t = 3.5 s
x =?
We know that,
x = Acos(2pie ft)
Putting all values in above eq.
x = 6.2 x cos(2x3.142x1.6x3.5)
x = - 4.8
Displacement can never be negative so ignore - sign.
I would say C.
Developing a plan is important because it will motivate you and tell you when to get things done. It is the most efficient
