The correct answer is <span>X–rays.
X-beams or X-rays are a kind of radiation called electromagnetic waves. X-beam imaging makes photos of within your body. The pictures demonstrate the parts of your body in various shades of high contrast. This is on account of various tissues retain diverse measures of radiation.

Answer:
the electron only emits electromagnetic radiation when it descends to a lower-energy orbit
Explanation:
Answer:
This represents radiation in ultra-violet region .
Explanation:
Energy of the orbit where n = 3 is given as follows
= -1.511 eV
Energy of the orbit where n = 1 is given as follows
= 13.6 eV
Difference of [tex]E_3 and [tex]E_1 = - 1.511+ 13.6
= 12.089 eV.
The wavelength of light having this energy in nm is given by the expression as follows
Wavelength in nm = 1244 / energy in eV
= 1244 / 12.089
= 102.90 nm
This represents radiation in ultra-violet region .
Answer:
i=1250000000Nm
ii=50000m/s
Explanation:
energy=force ×distance
500000N×(2.5×1000)m
=1250000000Nm
ii. Force=mass ×acceleration
500000N =40000kg ×a
500000 ÷40000=12.5a
s=1/2at^2
2500m=1/2×12.5×t^2
2500m=6.25×t^s
2500÷6.25=400
t^2=400
√t^2=√400
t=20seconds
speed=distance ×time taken
=2500m × 20s
=50000m/s
Answer:
Explanation:
Speed is a measurment that tells him much distance a body travels over a certain amount of time (usually measured in meters per second (m/c))
