Answer 1

Answer:

(a)$1.308\times 10^{-4}m/sec$

(b)57.33831 pound/cubic feet

(c)120.1095 hp

Explanation:

We have

(a) 760 miles / hour

We know that $1\ mile\ =0.00062m$

And 1 hour = 60×60=3600 sec

So $760miles/hour=\frac{760\times 0.00062meter}{3600sec}=1.308\times 10^{-4}m/sec$

(b) 927 kg/cubic meter to mass/cubic foot

We know that 1 kg = 2.20 pound

So 921 kg = 921×2.20=2026.2 pound

We know that 1 cubic meter = 35.31 cubic feet

So 57.33831 pound / cubic feet

(c) We have to convert to hp

$5.37\times 10^3kj/min=\frac{5.37\times 1000kj}{60sec}=89.5kj/sec$

We know that 1 kj /sec = 1.341 hp

So 89.5 kj/sec = 89.5××1.341=120.1095 hp
