Answer:

Call 911 or ask someone else to.

Explanation:

Call 911 or ask someone else to.

Lay the person on their back and open their airway.

Check for breathing. If they are not breathing, start CPR.

Perform 30 chest compressions.

Perform two rescue breaths.

Repeat until an ambulance or automated external defibrillator (AED) arrives.

These are most of the steps to CPR but the most important thing to do is call 911 or someone who can help bc if it doesnt work out right or if they stillneed air the paramedics will be there to help

5. A 4.00 kg object slides down a frictionless inclined plane with an acceleration of 3.00 m/s2. What is the angle of the inclin

Kazeer [188]

Answer:

The angle of the incline above horizontal is 17.81 degrees.

Explanation:

Given that,

Mass of the object, m = 4 kg

Acceleration of the object above the incline, $a=3\ m/s^2$

We need to find the angle of the incline above horizontal. The net force acting on the object along the incline is given by :

$F_{net}=mg\ sin\theta$

$ma=mg\ sin\theta$

$a=g\ sin\theta$

$sin\theta=\dfrac{a}{g}$

$sin\theta=\dfrac{3}{9.8}$

$\theta=17.81^{\circ}$

So, the angle of the incline above horizontal is 17.81 degrees. Hence, this is the required solution.

PLLEEEASE HELP!!! How does archimedes' principle explain how much fluid is displaced by an object?

Crank

The concept of Archimedes' principle is that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. The fluid displaced has a weight W = mg, where g is acceleration due to gravity. Therefore, the weight of the displaced fluid can be expressed as W = ρVg.
