A uniform solid cylinder of mass M and radius R is placed on a rough horizontal board of same mass , which in turn is placed on a smooth surface . The coefficient of friction between the board and the cylinder is ๐œ‡=0.3 . If the board starts acceleration with constant acceleration a , as shown in the figure , then the maximum value of a , so that the cylinder performs pure rolling is ……………… m/๐‘ ^2 , g = 10 m/๐‘ ^2

Two rigid boxes containing different ideal gases are placed on a table . Box A contains one mole of nitrogen at temperature ๐‘‡_๐‘œ , while box B contains one mole of helium at temperature 7/3 ๐‘‡_๐‘œ . The boxes are then put into thermal contact with each other and heat flows between them until the gases reach a common final temperature (ignore the heat capacity of boxes and heat exchange will happen only between boxes ) . Then the final temperature of the gases in terms of ๐‘‡_๐‘œ is 7/3 ๐‘‡_๐‘œ 3/2 ๐‘‡_๐‘œ 5/2 ๐‘‡_๐‘œ 3/7 ๐‘‡_๐‘œ

Kirchhoff law problem and equivalent resistance

Image
1. using Kirchhoff law find the current in following branch answer     AB:(5/8) A, CA: (5/2) A, DEB: (15/8) A AD: (15/8) A, CD: 0 A, BC: (5/2) A 2.  using Kirchhoff law find the current in following branch   Answer  current in branch AB= (4/17) A In branch BC = (6/17) A In branch CD = (4/17) A In branch AD= (6/17) A In branch BD = (-2/17) A Total Current =(4/17) +(6/17)+(-4/17)+(6/17)+(-2/17)=(10/17) A 4. find R Equivalent
