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.

According to Newton's Second Law of Motion :
The Force acting on an Object is equal to Product of Mass of the Object and Acceleration produced due to the Force.
Force acting = Mass of the Object × Acceleration
Given : Force = 50 newton and Mass of the Object = 10 kg
Substituting the respective values in the Formula, we get :
50 N = 10 kg × Acceleration
Acceleration of the Object = 5 m/s²
A) 50 cm
B) 10000 cm/s
Explanation
Step 1
A)
If you know the distance between nodes and antinodes then use this equation:
then, let
now, replace to find the wavelength
so, the wavelength is
A) 50 cm
Step 2
The speed of a wave can be found using the equation
or velocity = wavelength x frequency,
then,let
replace and evaluate
so
B) 10000 cm/s
