Hi,I want to know something.
Paha777 [63]

Answer:

So it looks to me that, Yes, you can find 10-50 leds on Amazon. You just have to be specific and search 10-50 led Christmas lights for windows, or something along those lines. Also try filtering the results, and reading the descriptions and reviews. This should help you out, and if it doesn't then I'm sorry.

Good luck friend :)

Intravenous infusions are usually driven by gravity by hanging the bottle at a sufficient height to counteract the blood pressur
Bingel [31]

Answer:

(a) BP = 11.99 KPa

(b) h = 2 m

Explanation:

(a)

Since, the fluid pressure and blood pressure balance each other. Therefore:

BP = ρgh

where,

BP = Blood Pressure

ρ = density of fluid = 1020 kg/m³

g = acceleration due to gravity = 9.8 m/s²

h = height of fluid = 1.2 m

Therefore,

BP = (1020 kg/m³)(9.8 m/s²)(1.2 m)

<u>BP = 11995.2 Pa = 11.99 KPa</u>

(b)

Again using the equation:

P = ρgh

with data:

P = Gauge Pressure = 20 KPa = 20000 Pa

ρ = density of fluid = 1020 kg/m³

g = acceleration due to gravity = 9.8 m/s²

h = height of fluid = ?

Therefore,

20000 Pa = (1020 kg/m³)(9.8 m/s²)h

<u>h = 2 m</u>

For a certain gas, Cp = 840.4 J/kg-K; and Cv = 651.5 J/kg-K. How fast will sound travel in this gas if it is at an adiabatic sta
Crank

Answer:

The speed of the sound for the adiabatic gas is 313 m/s

Explanation:

For adiabatic state gas, the speed of the sound c is calculated by the following expression:

c=\sqrt(\gamma*R*T)

Where R is the gas's particular constant defined in terms of Cp and Cv:

R=Cp-Cv

For particular values given:

R=840.4 \frac{J}{Kg-K}- 651.5 \frac{J}{Kg-K}

R=188.9 \frac{J}{Kg-K}

The gamma undimensional constant is also expressed as a function of Cv and Cp:

\gamma=Cp/Cv

\gamma=840.4 \frac{J}{Kg-K} / 651.5 \frac{J}{Kg-K}

\gamma=1.29

And the variable T is the temperature in Kelvin. Thus for the known temperature:

c=\sqrt(1.29*188.9 \frac{J}{Kg-K}*377 K)

c=\sqrt(91867.73 \frac{J}{Kg})

The Jules unit can expressing by:

J=N.m=\frac{Kg.m}{s^2}* m

J=\frac{Kg.m^2}{s^2}

Replacing the new units for the speed of the sound:

c=\sqrt(91867.73 \frac{Kg.m^2}{Kg.s^2})

c=\sqrt(91867.73 \frac{m^2}{s^2})

c=313 m/s
