A lengthy rope, mounted at one quit, vibrates as a sine wave on moving the free grow to be and
down. The man or woman preserving the rope notices 60 crests passing in 1 minute. The next
minute, the character doubles the charge of the rope movement. What is the frequency of the
waves inside the 2d minute?
A. 1 Hz
b. 2 Hz
c. 3 Hz
d. Four Hz - ANS-b. 2 Hz
One hertz is identical to one cycle in step with 2nd. Bird the charge of the rope movement is
doubled, there could be 120 crests in 60 seconds inside the subsequent minute; that is, a
frequency of two Hz
A patient has lung cancer. The case records shows that deposition of the radioactive element
radon within the lungs might also have triggered malignancy. Which ionizing radiation is
responsible for the malignancy?
A. X-rays
b. α particle
c. β particle
d. Gamma rays - ANS-b. α particle
A affected person walks into a radiology laboratory to go through a chest x-ray exam for the
primary time. The affected person asks the radiologic technologist, "Can I expand a radiation
burn after the system?" What would be the best response from the radiologic technologist?
A. "No, x-rays can not penetrate the skin to supply facet outcomes along with sunburn."
b. "Yes, slight results like sunburn can be experienced for some days after the x-ray."
c. "No, there may be no possibility of radiation burn from imaging approaches, even after
exposure to excessive-depth x-rays."
d. "Not probably, radiation burn can on occasion arise from positive CT scans or with
fluoroscopy, however not from a chest x-ray." - ANS-d. "Not in all likelihood, radiation burn can
once in a while occur from certain CT scans or with fluoroscopy, however now not from a chest
x-ray."
A radiologic technologist is acting an test to look at the mass equivalence of a photon of a
hundred kiloelectron volts (KeV) x-ray. Which concept must the radiologic technologist follow to
recognize the mass equivalence of the photon?
A. Wave equation
b. Quantum idea
, c. Theory of relativity
d. Inverse square law - ANS-c. Theory of relativity
The principle of relativity is used to calculate the mass equivalence of a photon from a known
electricity. The relativity equation is expressed as E = mc2, in which E is the strength, c is the
rate, and m is the mass to be measured.
A radiologic technologist is working on barium and iodine. Which term does the radiologic
technologist use to consult 134/fifty six Ba and 131/53 I ?
A. Isobar
b. Isomer
c. Isotope
d. Isotone - ANS-d. Isotone
Isotones range of their atomic numbers and mass numbers, but they have got the equal quantity
of neutrons, this is, a consistent for the amount a (atomic number) - z (mass variety) a-z.
A wave on a rope has a frequency of 20 Hz. How many crests are visible in 10 seconds?
A. 20
b. 50
c. 100
d. 200 - ANS-d. Two hundred
One crest in 1 2d offers a frequency of one Hz. A frequency of 20 Hz shows that 20 crests are
produced in a single 2nd. Therefore, in 10 seconds, 200 crests may be seen.
An atom has electrons organized in 4 orbital shells across the nucleus. A low-strength x-ray
ionizes the atom by means of ejecting an electron. Which shell is depleted through the loss of
this electron?
A. L
b. K
c. M
d. N - ANS-d. N
A minimum quantity of strength is required to cast off an electron from the N shell.
An atom has 4 orbital shells all in favour of electrons. What is the maximum number of electrons
which could exist within the third orbital shell?
A. Sixteen
b. 18
c. 20
d. 22 - ANS-b. 18
