A loaded coal wagon with a total mass of 20 000 kg is pushed by a force of 300 000 N. What was the wagon’s acceleration?
AlexFokin [52]

Answer:

<h2>15 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{300000}{20000}  =  \frac{30}{2}  \\

We have the final answer as

<h3>15 m/s²</h3>

Hope this helps you

A compound is made of 6.00 grams of oxygen, 7.00 grams of nitrogen, and 20.00grams of hydrogen. Find the percent composition of
xxTIMURxx [149]

The percent composition of the compound.

A O-18.18%, N-21.21%, H-60.60%

<h3>Further explanation</h3>

Given

6.00 grams of oxygen,

7.00 grams of nitrogen,

20.00 grams of hydrogen.

Required

The percent composition

Solution

Total mass :

= mass of O + mass of N + mass of H

= 6 + 7 + 20

= 33 g

% O = 6/33 x 100%= 18.18%

% N = 7/33 x 100%=21.21%

% H = 20/33 x 100% = 60.6 %

<span>I believe the answer is B)Diuretic therapy
</span>
The patient has alkalosis(pH 7.49), increased respiratory rate (20/min) and decreased carbon dioxide level(<span>pCO2 30). These findings point to respiratory alkalosis. 
The reason for increased respiratory rate probably because of heart failure that is shown by the decreased </span>cardiac index, pO2, <span>crackles, and wheezes. The treatment for congestive heart failure is to decrease the preload and blood pressure by giving a strong diuretic like furosemide.</span>
