Answer:
T=1022.42 N
Explanation:
Given that
l = 32 cm ,μ = 1.5 g/cm
L =2 m ,V= 344 m/s
The pipe is closed so n= 3 ,for first over tone
f= 129 Hz
The tension in the string given as
T = f²(4l²) μ
Now by putting the values
T = f²(4l²) μ
T = 129² x (4 x 0.32²) x 1.5 x 10⁻³ x 100
T=1022.42 N
Answer:
The object is moving away from the origin
The object started at 2 meters
The object is traveling at a constant velocity
Explanation:
The y-component of the acceleration is
Explanation:
The y-component of the ice skater acceleration can be calculated with the equation
where
is the y-component of the final velocity
is the y-component of the initial velocity
t is the time elapsed
Here we have:
- Initial velocity is at , so its y-component is
- Final velocity is at , so its y-component is
The time elapsed is
t = 8.33 s
Therefore, the y-component of the acceleration is

Answer:
Explanation:
<u>Tangent and Angular Velocities</u>
In the uniform circular motion, an object describes the same angles in the same times. If is the angle formed by the trajectory of the object in a time t, then its angular velocity is
if is expressed in radians and t in seconds the units of w is rad/s. If the circular motion is uniform, the object forms an angle in 2t, or in 3t, etc. Thus the angular velocity is constant.
The magnitude of the tangent or linear velocity is computed as the ratio between the arc length and the time taken to travel that distance:
Replacing the formula for w, we have
