C. a plane for forming a scientific hypotheses
Answer:
Nitropruside
Explanation:
Shock is a serious medical condition where oxygen levels in the body are low, causing a low blood pressure which can lead to organ damage and sometimes death. Shock can be caused by low blood volume or inadequate pumping action of the heart.
Nitropruside is a very potent vasodilator. It acts on the arterial and venous smooth muscles, causing smooth muscle relaxation and leading to decreased cardiac preload and afterload. A reduction in afterload gives rise to an increased cardiac output and blood supply to the cells is increased. This in turn reduces the need for the heart to pump more blood (a compensatory response by the heart due to the low oxygen levels), thereby reducing the oxygen demand of the heart.
Answer:
See explanation below
Explanation:
To get this, we need to apply the general expression for half life decay:
N = N₀e(-λt) (1)
Where:
N and N₀ would be the final and innitial quantities, in this case, masses.
t: time required to decay
λ: factor related to half life
From the above expression we need λ and t. To get λ we use the following expression:
λ = t₁₂/ln2 (2)
And we have the value of half life, so, replacing we have:
λ = 8.04 / ln2 = 11.6
Now, we can replace in (1) and then, solve for t:
0.75 = 40 exp(-11.6t)
0.75 / 40 = exp(-11.6t)
ln(0.01875) = -11.6t
-3.9766 = -11.6t
t = -3.9766 / -11.6

<span>Gamma radiation has a shorter wavelength, a higher frequency and higher energy than radio radiation.
Wavelength is inverse to frequency and energy (i.e. higher wavelength means lower frequency and lower energy, and vice versa).</span>
