Wave speed is 8 m/s
Explanation:
- Wave speed or speed of the wave is given by the formula
v = distance traveled by the wave/time
- Here, distance traveled = 16 m and time = 2 s
⇒ Wave speed = 16/2 = 8 m/s
Answer:
3/7 ω
Explanation:
Initial momentum = final momentum
I(-ω) + (2I)(3ω) + (4I)(-ω/2) = (I + 2I + 4I) ωnet
-Iω + 6Iω - 2Iω = 7I ωnet
3Iω = 7I ωnet
ωnet = 3/7 ω
The final angular velocity will be 3/7 ω counterclockwise.
Answer:
A. something pushes or pulls it to stop.
Explanation:
Newtons first law. hope this helps
a=(5.8-1.5)÷15.8
a=4.3÷15.8
a=0.27m/s
Explanation:
acceleration=final velocity - initial velocity /time
I think the answer is wind
