Choices 1,3,4 are supported.
Choice 2 is incorrect because a horizontal slope on a position time graph means the object is starionary.
Choice 5 is incorrect because the speed of an individual can be determined by calculating the slope at a point on the position time graph.
Resistance
R
of a conducting wire of length
l
and of area of cross section
A
is given by the expression
R
=
ρ
l
A
where
ρ
is resistivity or specific resistance of the material of the conductor.
Inserting given values in the expression in SI units we get

D. The flow of energy,heat, and work
The distance should be 11 cm and the image will be inverted (and smaller)
I used the Lens Equation:
Where:
obj. is the distance of the object
im. is the distance of the image
f is the focal length
About 360 meters I hope this helps
