The object's final velocity, given the data is 10.5 rad/s
<h3>What is acceleration? </h3>
This is defined as the rate of change of velocity which time. It is expressed as
a = (v – u) / t
Where
- a is the acceleration
- v is the final velocity
- u is the initial velocity
- t is the time
<h3>How to determine the final velocity</h3>
The following data were obtained from the question
- Initial velocity (u) = 1.5 rad/s
- Acceleration (a) = 0.75 rad/s²
- Time (t) = 12 s
- Final velocity (v) = ?
The final velocity can be obtained as follow:
a = (v – u) / t
0.75 = (v – 1.5) / 12
Cross multiply
v – 1.5 = 0.75 × 12
v – 1.5 = 9
Collect like terms
v = 9 + 1.5
v = 10.5 rad/s
Thus, the final velocity of the object is 10.5 rad/s

Answer:
f = 687.85 Hz
Explanation:
Given that,
The wavelength of sound wave,
We need to find the frequency of the sound wave. The relation between wavelength and frequency is given by :
v is speed of sound at T = 35°C = 308.15 K
So,
So, the frequency of the sound is 687.85 Hz.
Answer:
A vibration or oscillation is a periodically repeated reversal of the direction of movement.
Explanation:
Une vibration ou une oscillation est une inversion répétée périodiquement de la direction du mouvement.
Here is just another definition.
A vibration is periodic back-and-forth motion centerd around it's equilibrium.
Answer:
Check the explanation
Explanation:
Each number in the wheel spans 360/12 = 30 degree
Therefore 41.91 degree corresponds to the number 29 on the wheel when the wheel spins clockwise.
To me the basic difference is their frequency and wavelength.
For frequency :
Infrared < visible light < ultraviolet
For wavelength :
Infrared > visible light > ultraviolet
