A body weighing 108N moves with seed of 5ms–¹ in a horizontal circular path of radius 5m. Calculate the magnitude of the centrip
uysha [10]

Hi there!

Recall the equation for centripetal force;

\boxed{F_c = \frac{mv^2}{r}}

m = mass (kg)

v = velocity (m/s)

r = radius (m)

We are not given the mass directly, we are given the object's weight.

W = mg

108 = 10m \\\\m = 10.8 kg

Now, we can plug this value along with the given velocity and radius to solve:

F_c = \frac{10.8(5^2)}{5} = \boxed{54N}

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.

prisoha [69]
There is no SI "base unit" of density.
(Any unit of mass) divided by (any unit of volume) is
a valid unit of density.

The units of density that are seen most often are

(gram per cm³) and (kgm per meter³) .
