Answer:
Explanation:
The magnitude of the constant angular acceleration is the change in angular velocity over a unit of time. So if the angular speed increases from 8 rad/s to 12 rad/s in 4 seconds then the angular acceleration is:
Answer:
3240000 ft
Explanation:
There are 60 seconds in a minute so, multiply 60 seconds by 18 minutes. That equals 1080 seconds.
Since there are 3000 ft in each second, just multiply 1080 seconds by 3000 ft.
This question seems to really be incomplete. You must include the options but fortunately I have already encountered this problem.
Here are the choices:
<span>A. have a different frequency than the resultant wave.
B. be in phase with each other.
C. be traveling in the opposite direction of the resultant wave.
D. have a different wavelength than the resultant wave
The correct answer is letter B. be in phase with each other</span>
Answer:
2 number
Explanation:
Displacement is a vector. This means it has a direction as well as a magnitude and is represented visually as an arrow that points from the initial position to the final position.
