Answer:
image is 14.47 cm behind the lens
height is 2.11 mm
Explanation:
Given data
h = 2.03 cm
p = 1.39 m = 139 cm
focal-length f = 131 mm = 13.1 cm
to find out
Where is the image and How high is it
solution
we know focal length formula that is
1/f = 1/p + 1/q
put here value to find q
1/ 13.1 = 1/ 139 + 1 solbe/ q
q = 14.463066 cm
so image is 14.47 cm behind the lens
and
height is calculate
height / h = - q / p
put here all value
height = -14.47 / 139 × 2.03
height = −0.211324 cm
here -ve sign show image is inverted
so height is 2.11 mm
1/Rt = 1/R1 + 1/R2 + 1/R3+ 1/R4+ 1/R5
1/Rt = 1/6+ 1/6+1/6+1/6+1/6
1/Rt = 5/6
Rt = 6/5
Rt = 1.2 ohm
so B is the answer
Visible light has more energy than microwaves but it has a smaller wavelength than microwave
“a point representing the mean position of the matter in a body or system.”
Answer:
Nuclear medicine or PET scanning (Positron Emission Tomography)
Explanation:
Not super sure what your question is looking for but I think it can be either. PET is a technology used in the nuclear medicine field, and nuclear medicine is a broad field of using the technology the question described.
