Which of these describes an ethical dilemma that drug designers could face?
LenKa [72]

The statement 'whether people should take medicine or if they should seek alternative treatments' describes an ethical dilemma that drug designers face.

<h3>What is drug development?</h3>

Drug development refers to all the processes from target drug identification to drug validation and commercialization.

Drug development involves different stages of development including preclinical and clinical trials.

Ethical dilemmas in drug development include the release of a drug that is ineffective when compared to parallel treatments.

What is the <br>structure and symmetry operation of naphthalene​
d1i1m1o1n [39]

Answer:

Naphthalene has C2-rotational axis passing through the C9-C10 bond. It has two C2-axes perpendicular to the principal C2-rotational axis (one is passing through the mid-point of the C9-C10 bond another passing through the midpoints of C2-C3, C9-C10, C6-C7 bonds).

synergistic interlayer and defect engineering in vs2 nanosheets toward efficient electrocatalytic hydrogen evolution reaction
Sever21 [200]

It is stated that VS2 nanosheets with abundant defects and an extended (001) interlayer spacing as large as 1.00 nm, which is a 74% expansion as compared to that (0.575 nm) of the pristine counterpart, may be produced using a straightforward one-pot solvothermal process.

For the electrocatalytic hydrogen evolution reaction (HER), the interlayer expanded VS2 nanosheets display exceptional kinetic metrics, including a low overpotential of 43 mV at a geometric current density of 10 mA cm2, a small Tafel slope of 36 mV dec1, and long-term stability of 60 h without any current fading. The performance is even comparable to that of the commercial Pt/C electrocatalyst and significantly better than that of the pure VS2 with a typical interlayer gap.

Formula for finding speed using binding energy and mass​
makkiz [27]

Answer:

Energy equivalent to mass defect is termed as binding energy. A nucleus is like an inflexible spherical ball moulded by getting together a huge amount of miniature spherical balls in the nucleons form. Something is required to bound the nucleons collected. It is that something which assists as the glue. Every nucleon has to donate some of its mass, to deliver the energy resulting in a mass defect.

Binding Energy is also defined as the energy required to break down a nucleus into its component nucleons.

Binding Energy is expressed in terms of kJ/mole of nuclei or MeV’s/nucleon.

Binding Energy Formula

Binding Energy = mass defect x c2

where c= speed of light in vacuum

c = 2.9979 x 108 m/s.
