Answer:
v = 328.4
Explanation:
Data:
- Distance (d) = 785 m
- Time (t) = 2.39 s
- Velocity (v) = ?
Use formula:
Replace:
It divides:
What is the velocity?
The velocity is <u>328.4 meters per second.</u>
Answer:
length = 1.24m
Explanation:
velocity = frequency x wavelength
wavelength = velocity/frequency
w = 343/69 =4.97m
length = wavelength/4
length =4.97/4 =1.24m
Answer:
It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. ... The momentum of a body is equal to the product of its mass and its velocity.
Answer: D
Explanation: it seem right to me I really don't know if this right but I hope this helps
Are there any options or is it not multiple choice.
