Answer:
The dilation of time.
The falling of objects.
The changing of paths of light.
Explanation:
I have explained in the image attached below.
From the explanation, the correct ones are;
The dilation of time.
The falling of objects.
The changing of paths of light.
The image is present at 20cm from the crown glass spherical surface.
To find the answer, we need to know about the lens formula.
<h3>
What's the lens formula?</h3>
- It's (1/V)-(1/U)= (1/f)
- V= image distance from the lens, U= object distance, f= focal length of the lens
<h3>What's the image distance, if object is present at 20cm from crown glass of power 10DS?</h3>
- Focal length (f)= 1/ power = 1/10 = 0.1 m
- U= -20cm = -0.2m (-ve sign due to sign convection)
- (1/V)-(-1/0.2)= (1/0.1)
=> (1/V)+5=10
=> 1/V= 5
=> V=0.2m = 20cm
Thus, we can conclude that the image is present at 20cm.

He should cleverly, using charm and subterfuge, entice the dumbbell slowly in the direction of where he had hidden the scale. As long as Hunter isn't obvious about it, the dumbbell will swallow his faux charm, and will remain naively oblivious to his true purpose.
The answer is 30 ... same as the Atomic number.
