When using the lens equation, a negative value as the solution for di indicates that the image is real. Virtual. Upright. Invert
1 answer:
Option B is correct. A negative value as the solution indicates that the image is Virtual.
<h3>What is the lens equation?</h3>The Lens formula describes the relationship between the distance of an image (v), the distance of an object (u), and the focal length (f) of the lens in optics.
The lens equation is given below;
When light beams from the same spot on an item reflect off a mirror and diverge or spread apart, virtual pictures are formed.
Hence option B is correct. A negative value as the solution indicates that the image is Virtual.

Answer:
a. 900 J
b. 0.383
Explanation:
According to the question, the given data is as follows
Horizontal force = 150 N
Packing crate = 40.0 kg
Distance = 6.00 m
Based on the above information
a. The work done by the 150-N force is
= 900 J
b. Now the coefficient of kinetic friction between the crate and surface is
= .383
We simply applied the above formulas so that each one part could calculate
