whether or whether the conclusions apply to people whose location and circumstances differ from those of the study's participants need to asked to ensure both the external and internal validity of your results

<h3>How can external validity be guaranteed?</h3>

Broad inclusion criteria that produce a study group that more closely mimics real-life patients and, in the case of clinical trials, selecting interventions that are practical to implement can both boost external validity.

<h3>What steps would you take to make sure your study is reliable and valid?</h3>

The development of a solid study design, the selection of suitable methodologies and samples, and the meticulous and consistent execution of the research are all necessary for the reliability and validity of your findings.

<h2>Hello!</h2>

The answer is: A. 4.5 L

<h2>Why?</h2>

According to the conversion factor which states that:

1gal=3.78L

It means that we have 3.78 L per each gallon or it's equal to say that we 0.26 gallon per each L.The SI unit for liquid volume is the Liter (L)

Let's make the calculations:

1.2 gal*\frac{3,78L}{1gal} =4,54 L

So, we have 4.54 L in 1,2 gallons.

Have a nice day!

The gravitational force between two objects that are 2.1 times 10^-1 m apart is 3.2 times 10^-6 N. If the mass of one object is
Shtirlitz [24]

Answer:

Mass of the other object is 38.45 kg.

Explanation:

Given:

The gravitational force between two objects is, F=3.2\times 10^{-6} N

Mass of one object is, m_{1}=55\ kg

Distance between the objects is, r=2.1\times 10^{-1}\ m

Gravitational constant is, G =6.674\times 10^{-11}\ m^3 kg^{-1}s^{-2}

Let the mass of the other object be m_{2}\ kg

Gravitational force is given as:

F=\frac{Gm_1m_2}{r^2}

Plug in the given values and solve for m_2. This gives,

3.2\times 10^{-6}=\frac{6.674\times 10^{-11}\times 55\times m_2}{(2.1\times 10^{-1})^2}\\3.2\times 10^{-6}=\frac{6.674\times 10^{-11}\times 55\times m_2}{0.0441}\\3.2\times 10^{-6}=8.3236\times 10^{-8}m_2\\m_2=\frac{3.2\times 10^{-6}}{8.3236\times 10^{-8}}= 38.45\ kg

Therefore, the mass of the other object is 38.45 kg.

If there is "waste" energy, does the Law of Conservation of Energy still apply? please don't type something random if so i'll ju
FinnZ [79.3K]

Explanation:

Yes, the law of conservation of energy still applies even if there is waste energy.

The waste energy are the transformation products of energy from one form to another.

According to the law of conservation of energy "energy is neither created nor destroyed by transformed from one form to another in a system".

But of then times, energy is lost as heat or sound within a system.

  • If we take into account these waste energy, we can see that energy is indeed conserved.
  • The sum total of the energy generated and those produced will be the same if we factor in other forms in which the energy has been transformed into.
