The answer for sure is 5 m/s
Answer:
Its diameter increases as it flows down from the pipe. Assuming laminar flow for the water, then Bernoulli's equation can be applied.
P1-P2 + (rho)g(h1 - h2) + 1/2(rho)(v1² - v2²) = 0
Explanation:
P1 = P2 = atmospheric pressure so, P1 - P2 = 0
h1 is greater than h2 so h1-h2 is positive. Rearranging the equation above 2{ (rho)g(h1-h2) + 1/2(rho)v1²}/rho = v2²
From the continuity equation for fluids
A1v1 = A2v2
v2 = A1v1/A2
Substituting into the equation above
(A1v1/A2)² = 2{ (rho)g(h1-h2) + 1/2(rho)v1²}/rho
Making A2² the subject of the formula,
A2² = (A1v1)²× rho/(2{ (rho)g(h1-h2) + 1/2(rho)v1²}
The denominator will be greater than the numerator and as a result the diameter of the flowing stream decreases.
Thank you for reading.
The correct answer would be A. boiling point. And the reason to that is because pH, toxicity, and rusting ability are all examples of chemical properties.
The answer is A) velocity, because velocity is speed and displacement.
Hope this helps
The final speed of the combined masses is 0.21 m/s
Applying the law of conservation of momentum:
Total momentum before collision = Total momentum after collision.
⇒ Formula:
MU+mu = V(M+m).................. Equation 1
⇒ Where:
- M = mass of the first body
- m = mass of the second body
- U = Initial speed of the first body
- u = Initial speed of the second body
- V = common final speed.
From the question,
⇒ Given:
- M = 0.24 kg
- U = 0.60 m/s
- m = 0.26 kg
- u = -0.20 m/s (traveling in opposite direction)
⇒ Substitute these values into equation 1
- 0.24(0.6)+0.26(-0.20) = V(0.24+0.2)
⇒ Solve for V
- 0.144-0.052 = 0.44V
- 0.44V = 0.092
- V = 0.092/0.44
- V = 0.209
- V ≈ 0.21 m/s
Hence the final speed of the combined masses is 0.21 m/s
