A small object is placed at right angles to the axis of a fixed concave mirror so as to form i) real ii) a virtual image twice as long as the object It the radius of curvature is 40cm what is the
distance between the two images?​ (number 4)
​

the answer is b, have negligible mass

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
