Answer: 5 cm</h2>
In convex mirrors the focus is virtual and the focal distance is negative. This is how the reflected rays diverge and only their extensions are cut at a point on the main axis, resulting in a virtual image of the real object .
The Mirror equation is:
(1)
Where:
is the focal distance
is the distance between the object and the mirror
is the distance between the image and the mirror
We already know the values of 
and 
, let's find from (1):
(2)
(3)
On the other hand, the magnification 
of the image is given by the following equations:
(4)
(5)
Where:
is the image height
is the object height
Now, if we want to find the image height, we firstlu have to find from (4), substitute it on (5) and find :
Substituting (3) in (4):
(6)
Substituting (6) in (5):
Finally we obtain the value of the height of the image produced by the mirror:
Answer:
B

Spongy or the cancellous bone is the bone with lattice work structure
Answer:
Option (b) will be correct answer for accelerating the car
Explanation:
For accelerating the car we have to speed up the car
In option (b) it is given that stepping on the gas pedal to speed up the car so it is correct answer
In option (c) it is given that pressing the pedal to slow down the car it is a case of deceleration so it is a incorrect statement.
In option (d) it is given that speed is constant at curved path so acceleration will be zero because if there is no change in velocity then acceleration will be zero
