C. volume
D. mass
The image formed by the convex lens is real, located 10.91 cm to the right of the lens, and is inverted. The ray diagram would show rays from the object converging at the image point after passing through the lens.
In order to draw a ray diagram and find the location of the image for an object placed 30.0 cm to the left of a convex lens with a focal length of +8.0 cm, we first utilize what is known as the lens formula, which is 1/f = 1/do + 1/di. Here, f is the focal length of the lens, do is the object distance, and di is the image distance.
In the given question, the object distance (do) is -30 cm (the negative sign indicates that the object is on the same side of the lens as the light source), and the focal length (f) is +8 cm. Plugging these values into the lens equation, we find that 1/di = 1/f - 1/do = 1/8 - 1/(-30). Solving this, we get di = 10.91 cm.
This positive value for di means the image is real, meaning it can be projected onto a screen, and appears on the opposite side of the lens from where the object is. The magnitude of the image distance indicates the image is 10.91 cm from the lens.
To determine the orientation of the image, we use the magnification formula, m = -di/do. Substituting the given values into this formula, we get m = -10.91 / -30 = +0.36. Since this value is positive, the image is inverted. The image would appear smaller than the object because the absolute value of the magnification is less than 1.
