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

A possible explanation for the effectiveness of ________ is that it may reduce depression by triggering the long-term potentiati
k0ka [10]

Answer: Antidepressants

Explanation:

The effectiveness of ANTIDEPRESSANTS is best explained by how they stimulate the synapse junctions of several neurons in the body to a top frequency, thus inducing a continuous "feel-good" feeling in the patients administered such drugs.

This ability of antidepressants to sustain this "feel - good" feeling supresses depression and is known as the long-term potentiation of nerve cells.

Cell walls are impermeable to transport of most materials required for bacterial nutrition.
mezya [45]

The given statement is False.

The bacterial cells walls are composed of peptidoglycan, also known as murein. It comprises polysaccharide chains cross-linked by unusual peptides, involving D-amino acids. The bacterial cell walls are distinct from cell walls of fungi and plants that are made up of chitin and cellulose, respectively.

The cell walls in bacteria allow small molecules to pass through them freely, however, do not permit large molecules to pass through them, in this manner, it function as a coarse filter.

The main function of the cells wall is to sustain the shape of the cell and inhibit the cell from bursting due to osmotic pressure. The cell wall allows the components to pass, which are essential for bacterial nutrition.
