Answer:
Magnification = 1
Explanation:
given data
radius of curvature r = - 0.983 m
image distance u = - 0.155
solution
we get here first focal length that is
Focal length, f = R/2 ...................1
f = -0.4915 m
we use here formula that is
.................2
put here value and we get
<h3>v = 0.155 m </h3>
so
Magnification will be here as
m =
m =
<h3>m = 1</h3>
Answer:
Heating
Cooling
Water Heater
Washer and Dryer
Lights
Explanation:
mark as brainliest and drop some thanks!!
At condition 1:
I = mL^2
At condition 2:
I’ = m(2L)^2 = 4mL^2 = 4I
