Answer:

Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.

Water leaks out of a 3,200-gallon storage tank (initially full) at the rate V '(t) = 80 -t, where t is measured in hours and V i

kvasek [131]

Answer:

water leak is 650 gallons

time required to full drain is 80 hrs

Explanation:

given data

volume V = 3200 gallon

rate = V(t) = 80 - t

to find out

how much water leak between 10 and 20 hour and drain complete

solution

we know here rate is 80 - t

so here rate will be

$\frac{dV(t)}{dt}$ = 80 - t

and for time 10 and 20 hour

take integrate between 10 and 20

so water leak = $\int\limits^ {20}_ {10} {(80-t)} \, dt$ .....................1

water leak = ( 80t - $\frac{t^{2} }{2} )^{20}_{10}$

water leak = 650

so water leak is 650 gallons

and

we know here for full tank drain condition

water leak full = 80 t - $\frac{t^{2} }{2}$

3200 = 80 t - $\frac{t^{2} }{2}$

6400 = t² - 160 t

t = 80

so time required to full drain is 80 hrs

A fathom is a unit of length about 6 ft long commonly used in measuring depths of water. Because a fathom is about the length of

Naddik [55]

Distance to the moon = 4× $10^{8}$ m.

1 m = 3.28 ft

Distance to the moon in ft = 4× $10^{8}$ ×3.28 ft

= 13.12 × $10^{8}$ ft

1 fathom = 6 ft

Hence, distance to the moon in fathom

= $\frac{13.2}{6}$ × $10^{8}$

≈ 2× $10^{8}$ fathom
