Answer:
See description below
Explanation:
Given
Applied Force = 50N
Expected Appled Force = 350N
Difference = 350N - 50N
Difference = 300N
The frictional force will remain unchanged after the applied force gets to 300N.
At this point, the reason why the Net force is not zero (0) is because of the amount of force that is applied.
Also, since the frictional force is less than the applied force, the body will move in the right direction before it gets to 300 N the force of friction equals the applied force.
it is possible that, when oil reaches a high enough temperature, it can ignite and burn very fiercely, being difficult to extinguish.
Answer:
u = 8.3 x 10⁻⁴ m/s
Volume to Pass = 5 x 10⁻⁴ L = 0.5 mL
Explanation:
First we find area of pipe:
A = πd²/4
A = π(2.54 x 10⁻² m)²/4
A = 0.02 m²
Now,
Q = (1 L/min)(1 min/60 s)(0.001 m³/1 L)
Q = 1.66 x 10⁻⁵ m³/s
Therefore,
u = Q/A
u = (1.66 x 10⁻⁵ m³/s)/(0.02 m²)
<u>u = 8.3 x 10⁻⁴ m/s</u>
Time for 10 mL:
T = 0.01 L/Q
T = (0.01 L)/(1 L/min)
T = (0.01 min)(60 s/1 min)
T = 0.6 s
Liters of water to pass:
Volume to Pass = uT
Volume to Pass = (8.3 x 10⁻⁴ m/s)(0.6 s)
<u>Volume to Pass = 5 x 10⁻⁴ L = 0.5 mL</u>
