f=20cm
m=−2(red)
v=2u
Sign convention
u=−ve
v=+ve
f=+ve
Using lens formula,
1/v−1/u=1/f
⇒1/ −2u−1/u = 1/f1
→u=−3f/2 =−3×10/ 2=−15cm
Object should be placed at 15cm in front of the lens.

A solenoid is a generic term for a coil of wire used as an electromagnet. It also refers to any device that converts electrical energy to mechanical energy using a solenoid. The device creates a magnetic field from electric current and uses the magnetic field to create linear motion.

Spherical mirrors are of two types:
- Convex mirrors or diverging mirrors in which the reflecting surface is curved outwards.
- Concave mirrors or converging mirrors in which the reflecting surface is curved inwards. Some terms related to spherical mirrors:1. The centre of curvature (C) of a spherical mirror is the centre of the hollow sphere of glass, of which the spherical mirror is a part.
- The radius of curvature (R) of a spherical mirror is the radius of the hollow sphere of glass, of which the spherical mirror is a part.
- The pole (P) of a spherical mirror is the centre of the mirror.
- The principal axis of a spherical mirror is a straight line passing through the centre of curvature C and pole P of the spherical mirror.
- The principal focus (F) of a concave mirror is a point on the principal axis at which the rays of light incident on the mirror, in a direction parallel to the principal axis, actually meet after reflection from the mirror.
- The principal focus (F) of a convex mirror is a point on the principal axis from which the rays of light incident on the mirror, in a direction parallel to the principal axis, appear to diverge after reflection from the mirror.
- The focal length (f) of a mirror is the distance between its pole (P) and principal focus (F).
-
For spherical mirrors of small aperture, R = 2f.
Image formation by Spherical Mirrors:The nature, position and size of the image formed by a concave mirror depends on the position of the object in relation to points P, F and C. The image formed is real for some positions of the object. It is found to be a virtual image for a certain other position. The image is either magnified, reduced or has the same size, depending on the position of the object.

Inhalation is an active process because it requires energy and work. Expiration is typically a passive process that happens from the relaxation of the diaphragm muscle (that contracted during inspiration). The primary reason that expiration is passive is due to the elastic recoil of the lungs. Exhalation begins when inhalation ends. The process of inhalation occurs due to an increase in the lung volume (diaphragm contraction and chest wall expansion) which results in a decrease in lung pressure in comparison to the atmosphere; thus, air rushes in the airway. There is no contraction of muscles during exhalation; it is considered a passive process.
