Answer:
(A) Their high energy
Explanation:
The higher the energy of the x-ray the more "likely" they will pass through.
The x-ray is electromagnetic energy caused by energy changes in an electron.
X-ray are energetic and have enough energy to break up molecules. That is what reveals the bad or damaged cells in our body.
Answer:
Answer is A) Fermi
Explanation:
Fermi is the expressive unit for nuclear sizes. Fermi = 10^-15 meter.
V = u + at
0 = u -9.8 x 5.5
u = 9.8 x 5.5 = 53.9 m/s
Displacement = 0, assuming that he runs back to original position
Average velocity is displacement/ time, since displacement =0, velocity is also 0
Answer:
hey mate
answer is probably voltage as per me
as
Explanation:
Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points
