Answer: it's 12
Explanation:
Range is the difference between the highest and lowest numbers.
33-21=12
The convex mirror form an image by bouncing the light away from a focal point.
Answer: Option D
<u>Explanation:
</u>
A diverging mirror is a reflecting surface which is a spherical one. The bulging side of the convex mirror will face towards the light source. It is a diverging mirror in which rays diverge upon after reflection. These are often used in the mirrors that are in the automobiles.
The image that is formed by the convex mirror cannot be displayed on the screen. Hence, they are called as Virtual image. The resulting image by the convex mirror is upright, virtual and size diminished.
The other force that must be acting on the duck is upthrust of 10 N.
The given parameters;
- <em>weight of the rubber duck, W = 10 N</em>
<em />
When the weight of the object is equal to the upthrust, the apparent weight will be zero and the object will float in the liquid. This is known as principle of floatation.
Since the given weight of the rubber duck is 10 N, then the <em>upthrust</em> on the duck will be 10 N to enable the duck float on the water.
Thus, the other force acting on the duck is upthrust of 10 N.

In optics, chromatic aberration (abbreviated CA; also called chromatic distortion and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.[1] It occurs because lenses have different refractive indices for different wavelengths of light. The refractive index of transparent materials decreases with increasing wavelength in degrees unique to each.
