The answer is 
=
Thus, the average flow rate is 
.
What is average flow rate?
- Average flow, which is often represented in cubic feet per second, refers to the stream's average discharge at a certain location.
- The flowrate is the rate at which liquid travels through a pipe or into a wellbore from a reservoir.
- The volume of fluid that moves across a specific cross-sectional area per unit of time is known as the flow rate.
- It is essential to measure flow rates accurately using the right flowmeters to guarantee that fluid management procedures are efficient, safe, and cost-effective.

We will first convert lb to grams and in³ to milliliters.
350 lb : 2.205 = 158.75733 kg = 158,757.33 grams
1.3 · 10^4 in³ = 13,000 in³ = 13,000 · 0.016387064 = 213.031 liters
213.031 liters · 1,000 = 213,031 milliliters
Density = m / V = 158,753.33 g / 213,031 ml = 0.7452 g/ ml
Answer: A block of material will float.
Explanation:
Given data
Mass of skier m=65kg
Height of slope =80m
Potential energy possessed by the skier (positive work done) =12000J
Analysing his energy at half way point on the hill
Potential energy will be equal to kinetic energy
Applying the conservative principles of energy when the skier is at half way point in the hill
I.e
mgh= 1/2mv²
The masses will cancel out
gh=v²
Given g= 9.81m/s²
Let's solve for the velocity
v²=9.81*80
v=√784.8
v=28.0m/s
Now we can solve for the kinetic energy
KE= 1/2mv²
KE =1/2*60*28²
KE =47063.9/2
KE=23531.9J
Hence we can calculate the energy gained by the skier during his movement
Energy gained = KE-PE
= 23531.9-12000
= 11531.9J
Answer:
its inertia.
Inertia is the tendency of an object to continue in the state of rest or of uniform motion
Check the combination of the horses, review them, you'll get the answer.
