A 34-kg child runs with a speed of 2.8 m/s tangential to the rim of a stationary merrygo-round. The merry-go-round has a momentu
tekilochka [14]

Answer: 0.43\ rad/s

Explanation:

Given

Mass of child m=34\ kg

speed of child is v=2.8\ m/s

Moment of inertia of merry go round is I=510\ kg.m^2

radius r=2.31\ m

Conserving the angular momentum

\Rightarrow mvr=I\omega \\\Rightarrow 34\times 2.8\times 2.31=510\times \omega\\\\\Rightarrow \omega=\dfrac{219.912}{510}\\\Rightarrow \omega=0.43\ rad/s

Answer:

I tried

Explanation:

You have to check a 12 year olds respiration rate by Siting them down and trying to relax.  It's best to take the respiratory rate while sitting up in a chair or in bed.  Measure their breathing rate by counting the number of times their chest or abdomen rises over the course of one minute.  Then Record this number. Now you have to answer the first few  questions based on that.

Heart rate, blood pressure, respiratory rate and temperature are the big four vital signs.

8.  Secondary assessments are used in order to determine the injury, how the injury occurred, how severe the injury is, and to eliminate further injury and that is why it is important.

9. It should only be performed when a person shows no signs of life or when they are unconscious, unresponsive, not breathing or not breathing normally.  

In order to perform CPR, you need to check the scene and the person. Make sure the scene is safe, then tap the person on the shoulder and shout "Are you OK?" to ensure that the person needs help. Then pen the airway,  Check for breathing,  Push hard, push fast, deliver rescue breaths, continue CPR steps.

When does a circuit is said to be over loaded?​
Vlad [161]

Answer:

Every electric circuit in a wiring system must be protected against overloads. A circuit overload occurs when the amount of current flowing through the circuit exceeds the rating of the protective devices. The amount of current flowing in a circuit is determined by the load -- or the "demand" -- for current.

Explanation:

Hope this helps :)
