Answer:

2.2 cm

Explanation:

Pressure = force / area

P = F / A

A = F / P

A = 34 N / (9×10⁴ Pa)

A = 0.000378 m²

Area of a circle is:

A = πr²

0.000378 m² = πr²

r = 0.011 m

Diameter is double the radius:

d = 2r

d = 0.022 m

d = 2.2 cm

An object is 30 cm in front of a converging lens with a focal length of 10 cm. Use ray tracing to determine the location of the

Aleksandr-060686 [28]

Answer:

i). Inverted

ii). Magnification of the image = -0.5

iii). Real

Explanation:

As shown in the ray diagram attached,

An object AB has been placed in front of converging lens (convex lens) at u = 30 cm.

F (Focus) of the lens is at 10 cm. So F = 10 cm

By analyzing the ray diagram we can measure the distance of the image on the other side of the lens (By counting the small blocks of the graph)

V = 15 cm

Characteristics of the image is:

i) Inverted

ii) Magnification of the image = $-\frac{v}{u}=-\frac{15}{30}$

= -0.5

ii) Real
