To solve the problem it is necessary to apply the concepts related to Discharge. The flow rate is the amount of volume of a fluid that circulates in a given time

By definition it is represented as

Where,

v = Velocity

A = Area

However, as the name implies it can also be represented as

Where,

V = Volume

t = time

In our case we have the values of,

Therefore replacing all these data in the previous equation we have

It will take about 6 days to fill the pool.

Speed of the Enemy sub .....> <span> 25.0 km/hr which is (25/3.6) m/s = 6.94 m/s

We use the expression **Speed = Distance/ time **to find the distance

D = Speed*Time = 6.94 m/s * 3.5 = **24.305 m**

The enemy sub will be 24.305 m closer </span>

By idea gas equation we can say

here P = pressure

V = volume

n = number of moles

R = Avagadro gas constant

T = temperature

So from above expression you can see that for constant number of moleswe can say

So finally the volume will be 43.9 L

**Answer:**

10 m/s^2

**Explanation:**

Equation: F = ma.

a = acceleration

m = mass

F = force

Because we are trying to find acceleration instead of force we want to rearrange the equation to solve for a which is F/m = a.

F = 20

m = 2

a = ?

a = F/m

a = 20/2

a = 10 m/s^2
