They were both odd and obsessive
Answer:
10.25 seconds
Explanation:
Divide 400/39, leaves you with how many seconds it takes to travel that distance.
It's nice that this problem has everything in meters already, so that you don't have to do any unit conversions.
Answer:going uphill; downhill.
Explanation:A steep road is a road has a that 45-degree pitch and both mean that a run descends one vertical foot for each horizontal foot. For a one way mountainous road,if two vehicles meet at a steep point, the enabling traffic law states that the vehicle going uphill must back up for the one going downhill to pass through. This is to prevent any form of accident,as the vehicle descending will be coming with a very high velocity than the one trying to go uphill.
Answer:
v₂ = 16 m/s
Explanation:
We can use the continuity equation, which is as follows:
where,
A₁ = Area of inlet = πd²/4
A₂ = Area of outlet = π(d/2)²/4 = πd²/16
v₁ = velocity at inlet = 4 m/s
v₂ = velocity at outlet = ?
Therefore,
<u>v₂ = 16 m/s</u>
