Answer:
the answer is b. b velocity. remember v=v
Answer:
Explanation:
mass per unit length ρ = .100 / 1.65 = .0606 . kg /m
length of wire L = 1.65 m
For fundamental frequency , the expression is as follows
n =
L = 1.65 , T = 16 n and m = .0606
n =
= 4.9 /s .
This is fundamental frequency .
other mode of vibration ( first three ) will be as follows
4.9 x 2 = 9.8 /s ,
4.9 x 3 = 14.7 /s .
Answer:
(a) = 3910
(b) = 5181
(c) = 2762955 m
Explanation:
Using equations of uniformly accelerated motion:
Equations:
-
-
(a) Using equation 1:
⇒ Because it upward from rest
(b) Using equation 1:
⇒ Because is the is the initial speed in the movement before changing acceleration
(c) Using equation 2:
⇒ and Because it upward from rest
⇒
