Answer:
The correct answer is option B.
Explanation:
Concentration of a steady-state plasma ,= 25 mg/L
Weight of the volunteer =75 kg
Rate of infusion = 7.5 mg/kg hr
Concentration of steady-state plasma in 75 kg weight body:
Total body clearance of this drug:
The total body clearance of this drug is 22.5 L/hr.
Metals are good conductors of heat and electricity
Metals are good conductors due to presence of free electrons
They act as carrier to conduct heat or electricity.
So
Aluminum spoon will heat up as it is of metal
Iron spoon will heat up as it is of metal
Silver spoon will also heat up as it is of metal
Wood is a bad conductor of heat. It is an insulator
Wood has air space or pockets in its structure which makes it a bad conductor (it cannot conduct heat)
So a wooden spoon will be stay coolest as it is an insulator
one US ton is 2000 lbs, thus 2/5 of that is just their product.
answer: 800 lbs
the force between the electron and the proton.
a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
the radial acceleration of the electron.
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
the speed of the electron.
c) Now use a = v² / r
where a was found above
and r was given
<span> the period of the circular motion.</span>
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given
Answer:
A spectator ion is an ion that does not participate in a chemical reaction and is found in a solution before and after a reaction.
Hope this helped :)
