Answer:
The answer is "6:45 and 7:15".
Explanation:
In the given attache file two clocks are added, that's explanation defined as follows:
In the left image, it may assume, that the clock only at the right-hand side of a scene is move-in its previous position, which is shown to the left, as it was at 6:45 on the left but in the right image it will display the time that is 7:15.
The flow will be laminar if Reynold's number
is less than 2000.
Use the Reynold's formula and rearrange to calculate velocity of water in the pipe.
Where, 
is velocity of the fluid, 
is the diameter of pipe, and 
is the kinematic viscosity i.e. 
for water at 288.7 K from Appendix.
So, velocity is:
The flow rate <em>Q</em>:

Where A is the area of cross section of pipe.
The time taken to fill is:
Where V is the capacity of the tank.
Answer:
The acceleration would be positive, pointing to the right.
Explanation:
The acceleration tells us how velocity changes every second. If the train stops, this means its velocity must go from a non-zero value to zero.
To reduce velocity, acceleration must point to the opposite direction. Since velocity is negative, acceleration must be positive.
In my personal opinion, avoiding in not an effective conflict management strategy. When you are avoiding a conflict, you are really just pushing it to the side and it will need to be dealt with sooner or later. Avoiding a conflict is also ammeter thing to do as well, you should take responsibility and handle any situation.
Answer:
g = 5 m/s square
Explanation:
Weight(W), Mass(m), Gravity(g)
W = mg
1,000N = 200g
g = 1000/200
g = 5 m/s square
