A 3.39 cm tall object is placed in 36.7 cm in front of a convex mirror. The focal
1 answer:
Answer:
-11.8 cm
Explanation:
The position of the image can be found by using the mirror equation:
where:
f is the focal length of the mirror
p is the distance of the object from the mirror
q is the distance of the image from the mirror
In this problem, we have:
f = -17.4 cm is the focal length of the mirror (negative for a convex mirror)
p = 36.7 cm is the distance of the object from the mirror
By solving for q, we can find the position of the image from the mirror:
And the negative sign indicates that the image is virtual (on the opposite side of the mirror).

Explanation:
First we must explain the essential when we clear equations, and that is that if the term we need to clear is accompanied by other terms that are being added up, then those terms go to the other side of the equation to subtract if those terms are subtracting, then they go to the other side to add, if those terms are found multiplying then they go to the other side of the equation to divide and if those other terms are found dividing then they go to the other side of the equation to multiply.
(Primero debemos explicar lo esencial cuando despejamos ecuaciones, y es que si el término que necesitamos despejar va acompañado de otros términos que se están sumando, entonces esos términos van al otro lado de la ecuación para restar si esos términos están restando, luego van al otro lado para sumar, si esos términos se encuentran multiplicando luego van al otro lado de la ecuación a dividir, y si esos términos se encuentran dividiendo, pasan al otro lado de la ecuación a multiplicar.)
