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}](https://tex.z-dn.net/?f=-%5Cfrac%7Bv%7D%7Bu%7D%3D-%5Cfrac%7B15%7D%7B30%7D)
= -0.5
ii) Real
Answer:
m = 1.99 kg = 2 kg
Explanation:
The moment of inertia of a bicycle rim about it's center is given by the following formula:
![I = mr^{2}\\](https://tex.z-dn.net/?f=I%20%3D%20mr%5E%7B2%7D%5C%5C)
where,
I = Moment of Inertia of the Bicycle Rim = 0.21 kg.m²
r = Radius of the Bicycle Rim = Diameter of the Bicycle Rim/2
r = 0.65 m/2 = 0.325 m
m = Mass of the Bicycle Rim = ?
Therefore,
![0.21\ kg.m^{2} = m(0.325\ m)^{2}\\m = \frac{0.21\ kg.m^{2}}{(0.325\ m)^{2}}\\](https://tex.z-dn.net/?f=0.21%5C%20kg.m%5E%7B2%7D%20%3D%20m%280.325%5C%20m%29%5E%7B2%7D%5C%5Cm%20%3D%20%5Cfrac%7B0.21%5C%20kg.m%5E%7B2%7D%7D%7B%280.325%5C%20m%29%5E%7B2%7D%7D%5C%5C)
<u>m = 1.99 kg = 2 kg</u>
Answer:
In short, there are four types of natural silk produced around the world: Mulberry silk, Eri silk, Tasar silk and Muga silk. Mulberry silk contributes around as much as 90% of silk production, with the mulberry silkworm generally being regarded as the most important.
