Answer:

a = 8.65 m/s²

Explanation:

Conceptual analysis

We apply Newton's second law

∑F = m×a Formula (1)

∑F: algebraic sum of forces in Newton (N)

m: mass in kg

a: acceleration in m/s²

Known data

F = 19 N

F_f = 1.7 N

m = 2 kg

Problem development

We can see in the attached figure the free body diagram of the cart and we replace the data in formula (1), considering that positive forces are the ones that go in the same direction of acceleration:

19 - 1.7 = 2 × a

17.3 = 2 × a

a = 17.3 ÷ 2

a = 8.65 m/s²

Resultant force = mass × acceleration, therefore acceleration = resultant force ÷ mass
Resultant force = 19 - 1.7 = 17.3 N
acceleration = 17.3÷2= 8.65 ms-2

What did edison learn from his attempts to see his first patented invention
Simora [160]
This invention was a commercial failure. Edison resolved that in the future he would only invent things that he was certain the public would want. ... This gave Edison the money he needed to set up his first small laboratory and manufacturing facility in Newark, New Jersey in 1871.

An acute non-contagious respiratory tract infection that produces severe pneumonia-like symptoms caused by bacteria that thrive
Darina [25.2K]

Streptococcus infection carries all the symptoms mentioned.

<h3><u>Explanation</u>:</h3>

<em>Streptococcus pneumoniae</em> and <em>Diplococcus pneumoniae</em> are the organisms that gram positive bacteria. These bacteria enters the respiratory system from droplet method propagation which is through aerosol or water droplet inhalation which are infected with these bacteria. These bacteria leads to the severe antigen antibody reaction inside lungs which leads to high rate of mucous secretion. This leads to formation of pneumonia.

These bacteria are mainly seen in tropical countries with warm climate and humid environment. These bacteria doesn't spread through contagious methods like touching. But the protection must be taken as these patients cough can contain lakhs of these bacteria which are enough to infect a healthy individual.
