Answer:

Explanation:

Frequency is a magnitude that measures the number of repetitions/time of a wave.

Let's remember that a wave is a periodic movement whose propagation develops in a vacuum or in a physical environment.

Muiltplying 2.5 x 10^10 by 3.5 x 10^-7

andrey2020 [161]

Answer:

The value of $\left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right)$ is 8750

Solution:

$\left(2.5 \times 10^{10}\right) \times\left(3.5 \times 10^{-7}\right)$

$\Rightarrow\left(2.5 \times 10^{10} \times 3.5 \times 10^{-7}\right)$

$\Rightarrow\left(2.5 \times 3.5 \times\left(10^{10} \times 10^{-7}\right)\right)$

$\Rightarrow(2.5 \times 3.5) \times\left(10^{10+(-7)}\right)$

$\Rightarrow(2.5 \times 3.5) \times 10^{3}$

$\Rightarrow 8.75 \times 10^{3}$

$\Rightarrow 8.75 \times 1000=8750$

Two pipes with 1 meter diameters join to become one pipe with 2 meter diameter. Water was flowing in first pipe at 500 kg/s and

zloy xaker [14]

Answer:

The mass flow rate at the exit of the 2 meter diameter pipe is 1442 kg/s

Explanation:

If the oil is flowing in the 1m diameter pipe at 0.8 m/s, we can calculate the flow as

$Q=\bar{v}*A=\bar{v}*(\pi/4*D^{2} )=0.8m/s*0.785m^{2} =0.628m^{3}/s$

The mass flow is

$M=\rho*Q=1500 kg/m3*0.628m3/s=942kg/s$

The mass flow rate at the exit of the 2 meter diameter pipe is

$M=M_w+M_o=500 kg/s+942kg/s=1442kg/s$
