Does the rankine degree represent a larger or smaller temperature unit than the kelvin degree

zvonat [6]

The best and most correct answer among the choices provided by the question is the first choice, larger.

Rankine is Fahrenheit + 460 , while Kelvin is Celsius + 273. We all know that Fahrenheit has larger number compared to kelvin , thus rankine is much larger.
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.

Use Poiseuille's Law to calculate the rate of flow in a small human artery where we can take η = 0.028, R = 0.008 cm, l = 2 cm,

FrozenT [24]

Answer:

1.435 x 10^-4 cm^3/s

Explanation:

coefficient of viscosity, η = 0.028 poise

Radius, R = 0.008 cm

length, l = 2 cm

Pressure, P = 5000 dyne/cm^2

The Poiseuille's formula is given below

$V=\frac{\pi PR^{4}}{8\eta l}$

Where, V is the rate of flow, that means volume flowing per second

$V=\frac{3.14\times5000 \times {0.008}^{4}}{8 \times 0.028 \times 2}$

V = 1.435 x 10^-4 cm^3/s

Thus, the rate of flow is 1.435 x 10^-4 cm^3/s.

If evaporation cools the surrounding does condensation warm the surroundings ? explain

kykrilka [37]

Because evaporation requires heat (the latent heat of evaporation) and condensation releases heat (the latent heat of condensation).<span>

If a force F is exerted on a charged particle when the particle enters a magnetic field B at a velocity v, which of the followin

mixer [17]

Answer:

The correct option is 'c': The Force vector (F) and the magnetic field vector (B) are always perpendicular.

Explanation:

The magnetic force that acts on a charged particle moving in a magnetic field is given by

$\overrightarrow{F}=q\overrightarrow{v}\times \overrightarrow{B}$

As we can see that vector cross product is involved hence we conclude that Force vector (F) is always perpendicular to both the velocity vector (v) and the magnetic field vector (B) which may be at any angle with respect to each other.

Hence we conclude that vectors F and B are always perpendicular.
