what is the maximum height for a ball after n collisions if it loses 3/4 of its energy after each collision when dropped from a height h to a floor
A solid ball of radius R has a charge density given by = for 0 ≤ r ≤ R. The electric field outside the ball is :
Due to heavy floods in a state, thousands were rendered homeless, 50 schools collectively offered to the state governments to provide the place and the canvas for 1500 tents to be fixed by the government and decided to share the whole expenditure equally The lower part of each tent is cylindrical of base radius 2.8m and height 3.5, with the conical upper part of the same base radius but of height 2.1m. If the canvas used to make the tents cost 120 per sq.m, find the amount shared by each school to set up the tents. what value is generated by the above problem?
