The object should be placed 20/cm from the lens so as to form its real image on the screen
<h3>Mirror equation</h3>
The mirror equation is given according to the expression below;
1/f = 1/u + 1/v
where
f is the focal length
u is the object distance
v is the image distance
Given the following parameters
f = 5cm
v = 20cm
Required
object distance u
Substitute
1/5 = 1/u +1/20
1/u = 1/5-1/20
1/u = 3/20
u = 20/3 cm
Hence the object should be placed 20/cm from the lens so as to form its real image on the screen

Answer:
22.5 degrees
Step-by-step explanation:
We know that this full angle measures 90 degrees
and in the problem, it says that CBD is 1/4 of the full thing
so we can do
90/4=22.5
Answer:
ST=8.8
SR=15.5
Step-by-step explanation:
ST is the difference between S and T.
that would be 16.3-7.5=8.8
similarly RT is the difference between S and R
That would be 7.5-(-8)=15.5.
It’s an irrational number
Hope this helps!
