A child on a spinning playground ride is 0.36 m from the center of the ride. The centripetal force on the child is 19 N. What is the mass of the child if the child has a tangential speed of 0.54 m/s?

Answers

Answer 1

Answer:

Any motion in a curved path represents accelerated motion, and requires a force directed toward the center of curvature of the path. This force is called the centripetal force which means "center seeking" force. The force has the magnitude

F = mv^2 / r

Where f is the centripetal force

M is the mass

V is the velocity

R is the radius

19 N = m ( 0.54 m/s)^2 / 0.36 m

Solving for m

M = 23.5 kg

A student who weighs 500 newtons climbed the stairs from the first floor to the third floor,15 meters above, in 20 seconds. How much work did she do

Answers

Well, the 20 seconds gives us enough information to actually calculate the power she has on her feet :)
Well, the work is 500*15=7500J, that is 7.5 kJ or about 18 calories (1 cal is 418J?) The power is that 7.5 kJ divided by 20 seconds: 375W. That's... OK, I suppose...

Answer:

Work = (500N)(15m)=7500J Power= (7500J)/(20s) =375 W

What is mean by the net displacement in transverse wave

Answers

In a transverse wave, the particles are disturbed in a direction perpendicular to the direction of wave propagation. Thus, waves travel through a medium with no net displacement of the distance between two successive particles of wave that are in wavelength.

intravenous infusions are usually made with the help of the gravitational force. assuming that the density of the fluid being administered is 1,020 kg/m3, at what height should the iv bag be placed above the entry point so that the fluid just enters the vein if the blood pressure in the vein is 2.7 x 103 pa above atmospheric pressure? assume that the iv bag is collapsible. (hint: atmospheric pressure is applicable in the entire situation)

Answers

The IV bag should be placed approximately 10.19 meters above the entry point to ensure that the fluid just enters the vein, considering the blood pressure in the vein and assuming atmospheric pressure is applied.

Given:

Density of the fluid being administered = 1,020 kg/m³

Blood pressure in the vein = 2.7 × 10³ Pa above atmospheric pressure

Since the fluid is administered using gravitational force, the pressure at the entry point of the vein should be higher than the pressure at the IV bag.

The pressure difference can be calculated using the formula:

Pressure difference = density × gravitational acceleration × h

The pressure difference should be equal to the sum of the blood pressure in the vein and the atmospheric pressure:

Pressure difference = (blood pressure in the vein) + (atmospheric pressure)

h = (pressure difference) / (density × gravitational acceleration)

h = [(2.7 × 10³) + (101,325)] / (1,020 × 9.8)

h ≈ 10.19 meters

Therefore, the IV bag should be placed approximately 10.19 meters above the entry point to ensure that the fluid just enters the vein, considering the blood pressure in the vein and assuming atmospheric pressure is applicable throughout the situation.
