What mass of whole blood (in kg) can be contained in a plastic container whose dimensions are 125 mm by 110 mm by 35 mm? See cha

irakobra [83]

The mass of whole blood is 0.51 kg.

Given data:

The dimensions of container is 125 mmx 110 mm x 35 mm.

From the chart, the density of whole blood at 37 C is,

$\rho=\frac{1060kg}{m^3}$

The volume of container can be calculated as,

$\begin{gathered} V=125mm\times110mm\times35mm \\ V=481250mm^3\times\frac{1m^3}{10^{-9}mm^3} \\ V=4.8125\times10^{-4}m^3 \end{gathered}$

The mass of whole blood will be,

$\begin{gathered} \rho=\frac{m}{V} \\ \frac{1060kg}{m^3}=\frac{m}{4.8125\times10^{-4}m^3} \\ m=0.51kg \end{gathered}$

Thus, the mass of whole blood is 0.51 kg.

Which has more heat, a home oven at 500 degrees Celsius, or a one ton commercial oven at 500 degrees celsius?

alisha [4.7K]

A commercial oven because it is more durable plus it’s more professional so they use more heat then we do at home

How to find i1, i2,i3

MrRissso [65]

to find i1, i2, and i3 we need to find the total current.

to find the total current, you need to find the total resistance

you're already given the total voltage, Vs

to find Rtotal, start from the resistors furthest from the voltage source.

R3 and R4 are in series so

Rtotal= R3+R4 = 6+3 = 9 ohms

9 ohms is now in parallel with R2 so,

Rtotal= $(\frac{1}{R3+R4}) ^{-1}\\$ + (\frac{1}{R2}) ^{-1})^-1= (1/18)^-1 +( 1/9)^-1 = 6 ohms

6 ohms is in series with R1 so

Rtotal= 4+6=10 ohms

itotal= (\frac{Vtotal}{Rtotal})

= 120 v/10 ohms = 12 A

i total = i1 because all the current flows through it

i1= 12A

so the current splits into i2 and i3 and the amount of current that flows through a branch depends on the total resistance in each branch.

we already calculated the resistance in the R3+R4 & R2 branch as 6 ohms

since r3 and r4 are in series, the same current will flow through them

r3+r4 = 9 ohms

r2= 18 ohms

so the current in r2 will be half that of R3 & R4 (V=IR)

using the current divider rule

$Ix = Itotal * \frac{Rtotal}{Rx}$

i2= 12A x (6 ohms/18 ohms)= 4 A

i3= 12A x (6 ohms/9 ohms) = 8 ohms

Which term describes speed in a certain direction?

11Alexandr11 [23.1K]

Answer:

A. Velocity

Explanation:

Velocity is vector quantity thus has both magnitude and direction. It describes not only the speed but also the direction. Speed is scalar quantity so describes only speed but not direction. Energy has nothing to do with speed, acceleration describes change in velocity in a direction over time
