<u>Explanation:</u>
1) When we invest in stock it means we are investing in long term investment. It includes risk factor also.
2) We can make money from stocks by retaining them for a long period and selling them when their price rises.
3) dividends are paid out of distributable profits. Some companies provide dividends regularly which act as a regular source of income for investors.
4) Capital gain is the benefit obtained on selling a capital asset and if we face loss on selling the capital asset it results in capital loss. Capital assets are like stock, bonds, properties, etc.
Leading/trailing shoe type drum brake This is called the servo effect (self-boosting effect) which realizes the powerful braking forces of drum brakes. ... This is because drum brakes generate the same braking force in either direction. Generally, this type is used for the rear brakes of passenger cars.

Answer:
The fraction of isotope 1 is 50.7 % and fraction fraction of isotope 1 is 49.2 %.
Explanation:
Given that
Weight of isotope 1 = 78.918 amu
Weight of isotope 2 = 80.916 amu
Average atomic weight= 79.903 amu
Lets take fraction of isotope 1 is x then fraction of isotope 2 will be 1-x.
The total weight will be summation of these two isotopes
79.903 = 78.918 x + 80.916(1-x)
By solving above equation
80.916 - 79.903 = (80.916-78.918) x
x=0.507
So the fraction of isotope 1 is 50.7 % and fraction fraction of isotope 1 is 49.2 %.
= 0.75 V, 
= 0.56 A
<u>Explanation:</u>
Given data:
= 3 V
= 1 Ω
= 
Solution:
Using Kirchhoff's voltage law.
The law states that the algebraic addition of potential difference in loop is similar to zero.
- - = 0
- =
3 - × 1 =
12 - 3 = 4
3 - 3 =
= 3/4
= 0.75 V
=
= 
× 0.75
= 
= 0.56 A.
