Low blood pressure may cause the net hydrostatic pressure of a capillary to be less than normal. This will result in a(n) ______
monitta

Low blood pressure may cause the net hydrostatic pressure of a capillary

to be less than normal resulting in decreased net filtration pressure.

<h3>What is Pressure?</h3>

This is force applied to a body per unit area and it can be calculated by the

following below:

Pressure = Force/Area

When the net hydrostatic pressure of a capillary is less than normal, the

glomerular blood hydrostatic pressure (GBHP) decreases thereby resulting

in a corresponding decrease in net filtration pressure.

A record turntable is rotating at 33 rev/min. A watermelon seed is on the turntable 7.8 cm from the axis of rotation. (a) Calcul
Novosadov [1.4K]

Given data:

● Angular velocity of the turntable ω = 33 rev/min

Therefore,

ω = 33 rev/min

ω = 33rev/min × 2π rad/rev × 1 min/60 sec = 3.45 rad/s

● The distance of the watermelon seed from the axis of rotation r = 7.8 cm = 0.078 m

● μs = the coefficient of static friction

Section a:

The seed is undergoes circular motion and it is been effected by centripetal acceleration.

ac = rω^2

ac = 0.078 × 3.45^2

ac = 0.9284 m/s^2

Therefore,

the centripetal acceleration of the seed is 9.274 m/s^2

Section b:

If the seed is observed not to slip at the course of the circular motion, then the supplied frictional force given by the seed and surface of turntable would at least be equivalent to the centripetal force working on the seed.

Centripetal Force = Frictional Force

mrω^2 = μsmg

μs = rω^2 /g

μs = 0.078 × 3.45^2

------------

9.81

μs = 0.09464

Thus,

the coefficient of static friction is 0.09464.
