He's accelerating at 3 m/s² .
That means his speed is increasing by 3 m/s every second.
At the end of 8 seconds, his speed is (8 x 3 m/s) = 24 m/s .
He's been moving south for the whole 8 seconds.
So at the end of that time, his velocity is
24 m/s south .
Answer:
Yes, cause when listener is far away from music source... the listener feels it's pleasant.... but when observer approaches near loudspeaker... sound become unpleasant..........sound becomes noise when frequency crosses 85 Decibels.....so you can say that the voice from loudspeaker also get shrill when the listener reaches the surrounding source......
Answer:
Explanation:
Given
Current in the conductor
maximum Force
If Poles Faces are 55.5 cm in diameter i.e. Length
Force experience by a current carrying conductor is given by
where
thus Strength of Magnetic Field is 0.263 T
V = p / m
V = 1000 / 2.5
V = 400 m/s
hope this helps!
Answer:
Vf = 21 m/s
Explanation:
Data:
- Initial Velocity (Vo) = 15 m/s
- Acceleration (a) = 2.0 m/s²
- Time (t) = 3 s
- Final Velocity (Vf) = ?
Use formula:
Replace:
- Vf = 15 m/s + 2.0 m/s² * 3s
Multiply the acceleration with time:
Solve the sum:
The velocity of the car at the end of the 3 second interval is <u>21 meters per second.</u>
