I think it’s the cardiovascular system
For the first hour, the slope is zero.
After that, the slope is -2 miles per hour.
Answer:
Option A) n
Explanation:
In accordance to Quantum Mechanical model of an atom:
- The Principle Quantum number (n) gives the description of the shell of an electron and the energy level of an electron in an atom.
- The angular momentum also referred to as Azimuthal Quantum number (l) gives the description of the shape of the orbitals and helps in determination of angular momentum magnitude.
- The magnetic quantum number (
) describes the energy levels or the number of orbitals contained in a subshell and the way these are oriented within.
- The spin quantum no. (
) determines the elelctron spin's direction which may be (
) or (
).
Answer:
f_D = =3.24 N/m
Explanation:
data given
properties of air

k = 0.0288 W/m.K
WE KNOW THAT
Reynold's number is given as


= 1.941 *10^4
drag coffecient is given as

solving for f_D


Drag coffecient for smooth circular cylinder is 1.1
therefore Drag force is

f_D = =3.24 N/m
Explanation:
Given that,
Potential = 75 kV
Exposure = 200 mR
Time = 0.2 sec
We need to calculate the x-ray fluence during this chest x-ray exam
Using formula of fluence

Put the value into the formula


We need to calculate the energy fluence
Using formula of energy fluence


We need to calculate dose -equivalent delivered to the bone, muscle, and fat
Using formula of dose

Where, D = dose
E = energy
t = time
Put the value into the formula


Hence, This is the required solution.
