Mumbai Metro VS Lahore Metro Comparison in Hindi | #shorts #short #youtubeshorts

The metro which has been recently inroduced in Mumbai, encounters a sharp turn between Andheri and Chakala. To avoid any derailing issues, the authorities thought of banking the rails.The turn is of a radius of 400 m and the maximum speed attained by Mumbai Metro is 72 km//hr . IF the distance between the rails is 1 m then through what height should the outer rail be raised?

The given bar chart shows the sales of books in four metro branches ofa company for the years 2014 and 2015 In the given bar chart the ratio the total sales between Mumbai and Delhi is

(i) A block is connected to an ideal spring on a horizontal frictionless surface. The block is pulled a short distance and released. Plot the variation of kinetic energy of the block vs the spring potential energy. (ii) A ball of mass 200 g is projected from the top of a building 20 m high. The projection speed is 10 m/s at an angle theta=sin^(-1)(3/5) from the horizontal. Sketch a graph of kinetic energy of the ball against height measured from the ground. Indicate the values of kinetic energy at the top and bottom of the building and at the highest point of the trajectory, specifying the heights on the graph. Neglect air resistance and take g = 10 m//s^(2)
