Answer:
12ma²
Explanation:
The moment of inertia I = ∑mr² where m = mass and r = distance from shaft
Since we have three masses,
So, I = m₁r₁² + m₂r₂² + m₃r₃² where m₁ = first mass = m, m₂ = second mass = 3m and m₃ = third mass = 2m. Also, r₁ = distance of first mass from shaft = a, r₂ = distance of second mass from shaft = a and r₃ = distance of third mass from shaft = 2a.
I = m₁r₁² + m₂r₂² + m₃r₃²
I = ma² + 3ma² + 2m(2a)²
I = ma² + 3ma² + 2m(4a²)
I = ma² + 3ma² + 8ma²
I = 12ma²
The condensed Q formula may be used for operations in which the friction loss can be determined for a: 3, 4, or 5 inch hose.
<h3>What is a firehose friction loss?</h3>
A firehose friction loss can be defined as a measure of the effect of the resistance of water against the inner side of a firehose, which typically results in a pressure drop at the terminal end.
Generally, some of the factors that affect the resistance or friction in a firehose include:
Mathematically, the firehose friction loss can be calculated by using this formula:
FL = C × (Q/100)² × L/100.

Answer:
Phone, Eating, People in the car
Explanation:
your phone should always be off while driving and put away. Eating much like texting takes your attention away from the road so you should wait till you're parked or home to eat. People thrashing around or talking very loudly can be a terrible distraction. Ask them nicely to quiet down so you can focus on the road.
