Answer:
Explanation:
Given
mass of body
radius of circle
Time Period
suppose is the angular velocity of revolution
therefore
Centripetal acceleration
therefore centripetal
P 1 = 101,325 Pa (atmospheric pressure)
Milk has almost same density as water: (Rho)= 1,000 kg /m³
P 2 = 101,325 Pa + 1,000 kg/m³ · 9.81 m/s² · 0.1 m = 102,306 Pa
The hydrostatic equation:
P 1 + (Rho)v1² / 2 = P 2 + (Rho)·g·h2
101,325 + 1,000 v1²/2 = 102,306 + 1000 · 9.81 · 0.1
500 v 1² = 102,306 + 981 - 101,325
v 1² = 3.924
v 1 = √ 3.924
v 1 = 1.98 m/s
The initial velocity of outflow is 1.98 m/s.
Can you please help me with my school troubles grades are finalized tomorrow 13
Answer: Positive velocity is then speed towards right, and negative velocity is speed towards left. It is the same for acceleration: negative acceleration is acceleration towards left. It slows objects moving towards right
Explanation: In physics calculations, acceleration — just like displacement and velocity — can be positive or negative. can u help me now pls ?
