A car is travelling at a velocity of 20m/s. After 30sec it covers a distance of 1200 m. Calculate the acceleration of the car an
Umnica [9.8K]

Answer:

Acceleration: a = 1,3333 \frac{m}{s^{2} }

Final velocity: v = 60 \frac{m}{s}

Explanation:

To calculate the acceleration, you start from the formula:

s = v_i t+\frac{1}{2}at^{2}

Thus:

a = \frac{ 2(s - v_it)}{t^{2}}

Now that you have the accelration, you can use the this formula to calculate the final speed:

a = \frac{v_f - v_i}{\Delta t}

Thus:

v_f = a \Delta t + v_i

A viscous fluid is flowing through two horizontal pipes. The pressure difference P1 - P2 between the ends of each pipe is the sa
777dan777 [17]

Answer:half of shorter Pipe

Explanation:

Fluid is Flowing through two horizontal pipes with pressure difference

P_1-P_2=\Delta P

Both pipes have same radius

Length of one Pipe is twice of other

Let Longer Pipe be denote by 1 and smaller by 2

From Hagen Poiseuille equation

\Delta P=\frac{128\mu L\cdot Q}{\pi D^4}

Where \mu =viscosity of medium

L=length of Pipe

Q=discharge

D=diameter

For longer Pipe

\Delta P=\frac{128\mu 2L\cdot Q_1}{\pi \cdot D^4}----1

For smaller Pipe

\Delta P=\frac{128\mu L\cdot Q_2}{\pi \cdot D^4}------2

From  1 &  2 we get

2L\cdot Q_1=L\cdot Q_2

Q_2=2Q_1

volume flow rate of longer pipe is half of smaller pipe
