Part a)

Flow rate is defined as rate of volume flow

it is determined by

$Q = \frac{dV}{dt}$

now if the radius of pipe is reduced then we assume here that liquid flow is ideal flow here and there is no change in the density of liquid.

So here we know that since mass is always conserved

$\frac{dm}{dt}_{in} = \frac{dm}{dt}_{out}$

so we have

$\rho\frac{dV}{dt}_{in} = \rho\frac{dV}{dt}_{out}$

$\frac{dV}{dt}_{in} = \frac{dV}{dt}_{out}$

now we can say from above equation that there is no effect on the flow rate is we change the radius of pipe

Part b)

now in order to find the speed of flow'

$\frac{dV}{dt}_{in} = \frac{dV}{dt}_{out}$

$A_{in}v_{in} = A_{out}v_{out}$

$\pi r^2 v_{in} = \pi (\frac{r}{n})^2 v_{out}$

$v_{in} = \frac{v_{out}}{n^2}$

so final speed will be

$v_{out} = n^2 v_{in}$

here we have n = 3

$v_{out} = 9* v_{in}$

so flow speed will be 9 times more than initial speed

A massless string connects a 10.00 kg mass to a 13.00 kg cart which is resting on a frictionless horizontal surface. The mass ha

ch4aika [34]

The cart's acceleration to the right after the mass is released is determined as 7.54 m/s².

<h3>Acceleration of the cart</h3>

The acceleration of the cart is determined from the net force acting on the mass-cart system.

Upward force = Downward force

ma = mg

13a = 10(9.8)

13a = 98

a = 98/13

a = 7.54 m/s²

Thus, the cart's acceleration to the right after the mass is released is determined as 7.54 m/s².

yKpoI14uk [10]

Answer:

Wavelength

Explanation:

Wavelength is the distance between two corresponding consecutive phases of a waveform. It is usually represented by λ in the mathematical expressions.

A continuous propagating wave repeats its wavelength over the distance.

A wave has crest and trough with respect to time and space.

Wave is defined as a disturbance of any parameter repeated in a cyclic manner over the given time.
