Answer:
82.4 cm
Explanation:
The object and screen are kept fixed ie the distance between them is fixed and by displacing lens between them images are formed on the screen . In the first case let u be the object distance and v be the image distance
then ,
u + v = 184 cm
In the second case of image formation , v becomes u and u becomes v only then image formation in the second case is possible.
The difference between two object distance ie( v - u ) is the distance by which lens is moved so
v - u = 82.4 cm
I think it’s d but I’m not sure
The angle of baking from the calculation is obtained as 30°.
<h3>What is banking?</h3>
The term banking refers to a means of preventing vehicles from skidding off the road at curves.
We know that the banking angle is obtained from;
θ = tan-1(v^2/rg)
v = 24.5 m/s
r = 110 m
g = 9.8 m/s^2
θ = tan-1(25^2/9.8 * 110)
θ = tan-1(625 /1078)
θ = 30°
