Answer:
an absorber of x-ray
Explanation:
To make x-ray detection/vision work, you will need at least two items: a source of x-ray and absorbed or x-ray.
The object you want to see itself doesn't have to be the source, but it has to absorb some of the rays instead.

Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
Answer:
n = 3.26
Explanation:
given,
human need 380 W of power to walking 5 Km/hr
human body 380 J of energy per second for walking 5 Km/h
speed of human 5 x 0.278 = 1.39 m/s
for walking 1.39 m energy required = 380 J
distance traveled in 3 hours of walking
d = 1.39 x 3 x 3600
d = 15012 m
energy needed
E = 4,104,000 J
now,
one pizza slice give 1260000 J pf energy
slice of pizza
n = 3.26
