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

An experiment is done on three tomato plants over a 50 day period to test the following hypothesis: If either fertilizer or comp
olchik [2.2K]

Pot A that contained no fertilizer or compost will serve as a control in this experiment.

<h3>What is Fertilizer?</h3>

Fertilizer may be defined as any chemical or natural substance which is added to the soil with the intention to enhance the soil productivity.

Pot B contained fertilizer, while pot C contained compost, they will definitely grow more than pot A, but pot A serve as a control for this experiment because it does not contain any added resources into it. Hence, it grows naturally.

Thus, it is well described above.

Scientists studying transcription in yeast (Saccharomyces cerevisiae) created an experimental strain that
Ray Of Light [21]

Answer:

Explanation:

Hello!

The scientist created an experimental strain that produces a modified RNA polymerase with a single amino acid substitution. This mutation is supposed to change the elongation rate of the mRNA during transcription.

The dependent or response variable, is the one the researchers are interested in, meaning, are the characteristics that the researcher will pay attention to and measure during the experiment.

In this example, the researcher is interested in testing the max elongation rate during transcription, which is the dependent variable of this experiment.

In the second part of the experiment, both strains of yeast, wilds, and experimental, where exposed to 40ug/mL solution of amanitin and recorded the maximum elongation rate of the RNA. This is naturally to test the effects of amanitin over the elongation rate of the mRNA in both strains.

The control group is a set of experimental units that are exposed to the same conditions as the experimental groups, with the exception that they receive no treatment (or they receive a "no effective" treatment often called a placebo). The purpose of a control group is to know the natural response of the experimental units to a treatment-free environment, this way when comparing both groups, the researcher will be able to observe the differences or changes due to the applied treatments.

In the second experiment, there are missing two control groups, one made of the wild strain and the other made of the experimental strain, exposed to the same conditions as the treated strains.

I hope this helps!

How does the density of liquid water compare with the<br> density of ice?
Orlov [11]

Answer:

The normal pattern for most compounds is that as the temperature of the liquid increases, the density decreases as the molecules spread out from each other. ... The ice structure takes up more volume than the liquid water molecules, hence ice is less dense than liquid water.
