Answer:
200 m\ s Ans .....
Explanation:
Data:
f = 200 Hz
w = 1.0 m
v = ?
Formula:
v = f w
Solution:
v = ( 200)(1.0)
v = 200 m\s <em>A</em><em>n</em><em>s</em><em> </em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em>
The answer is 8 meters per second 8m/s because 200 divided by 25 is 8
Machine C. Machine A has an efficiency of 250/1000 = 0.25 = 25%, Machine B's efficiency is 350/500 = 0.7 = 70% and Machine C has an efficiency of 150/200 = 0.75 = 75%.
V = 20 m/s
Ecin = 1.8 x 10^5 J
Ecin = m*v^2/ 2
1.8*10^5 = m*400/2
200m = 1.8*10^5
I know you can do it :)
