Answer:
75 to 63 which is a drop of 12 degrees over a period of 10 seconds.

Answer:
Do we have to choose out of those three?
Explanation:
Answer
given,
diameter of segment 1, d₁ = 1 cm
diameter of segment 2, d₂ = 2 cm
diameter of segment 3 , d₃ = 0.5 cm
speed of liquid in first segment, v₁ = 8 m/s
a) using continuity equation
A₁ v₁ = A₂ v₂
v₂ = 2 m/s
speed in the second segment = 2 m/s
b) again, using continuity equation
A₂ v₂ = A₃ v₃
v₂ = 32 m/s
speed in the second segment = 32 m/s
c) Flow rate in the pipe
Q = A₁ V₁
Q = 6.28 x 10⁻⁴ m³/s
Q = 62.8 L/s
discharge in the pipe is equal to 62.8 L/s
Answer:
Not sure which statements were give to you for this question, but the vehicle's acceleration from noon to 2:00 PM was <em>zero</em>, the vehicle had a <em>positive</em> acceleration between 2:00 pm and 3:00 pm, and the vehicle had a <em>negative</em> acceleration at 4:30 PM.
Explanation:
From 12:00 PM to 2:00 PM, the vehicle traveled at a constant velocity of 70 MPH, meaning there wasn't any change to the speed. The velocity <em>remained the same</em>. An hour later, the velocity of the vehicle <em>increased</em> to 80 MPH, and finally at 4:30 PM, the velocity of the car <em>decreased </em>and was at 40 MPH.
Three mile 2 was an accident of a completely different type from Chernobyl. Unlike Chernobyl, TMIS 2s reactor vessel did not fail and contain almost all of the radioactive material. Containment at TMIS didn't fail
