(iv) The power of a convex lens increases when the lens is cut into two identical plano-convex lenses.

<h3>What is power of a lens?</h3>

The power of a lens is defined as the reciprocal of its focal length. It is measured in diopters.

<h3>Factors affecting the power of a lens</h3>

The power of a lens depends on the focal length of the lens which depends on;

  • the refractive index of the glass from which it is made, and
  • on the curvature of its two surfaces

P = 1/f

where;

  • P is power of the lens
  • f is focal length of the lens

When the focal length decreases, the power of the lens increases.

Thus, the power of a convex lens increases when the lens is cut into two identical plano-convex lenses.

Suppose the initial position of an object is zero, the starting velocity is 3 m/s and the final velocity was 10 m/s. The object
Nookie1986 [14]

Explanation:

We have,

The initial position of an object is zero.

The starting velocity is 3 m/s and the final velocity was 10 m/s.

The object moves with constant acceleration..

The area covered under the velocity-time graph gives displacement of the object. The correct option is "the area of the rectangle plus the area of the triangle under the line".

balandron [24]
Hey

Potential Difference given is : 2V

Resistance is : 2 ohms

By Ohm's Law, one can easily utilize the relation :

v = ir

Where, { v , i , r } are the potential difference, current and Resistance Respectively.


Hence,
i =  \frac{v}{r}  =  \frac{2}{2}  = 1a

Hence, the Current is 1 Ampere

blondinia [14]
When an elevator is accelerating downward, the normal force is equal to mg-ma (hence you feel a little lighter when accelerating downwards)

Therefore, the upward force of the elevator floor on the person must be less than 750N
