problems involving elastic and inelastic collisions in one dimension

Suppose X = ab Let D a and D b be absolute errors in measurements of quantities a and b, values of a and b and D X be the maximum possible error in X. Dividing both sides by X = ab, we get are relative errors of fractional errors in values of a, b and x. Neglecting as its product is ver..

The equation that involves one (or) more derivatives of some unknown functions which are required to be found is called => Non linear equation or Differential equation or Linear equation or Quadratic equation..

>Law of conservation of energy states that the total energy of an isolated system cannot change. A collision is said to take place when either two bodies physically collide against each other or when the path of one body is changed by the influence of the other body. A coll..

Why does a gas exert pressure on the walls of container? Consider only those molecules which are moving horizontally. Each molecule hits the container wall and bounces back with the same speed, because the collision is elastic. The molecule then travels in the opposite directio..

A wooden paperweight in the shape of a cone weighs 0.12 lb. What is the weight of a similar paperweight, which has double the dimensions of the first one? => 0.96 lb or 0.6 lb or 0.5 lb or 2 lb..

The length, width and height of a rectangular shed are 3m, 2m and 1m respectively. The volume of the shed is doubled when each dimension is increased by the same amount. Find the amount of increase in each dimension to the nearest tenth. => 0.4 m or 0.5 m or 0.3 m or 0..

A rectangular prism is 4 in. × 2 in. × 1 in. Find the volume of the prism after each dimension is tripled. => 21 in. 3 or 8 in. 3 or 7 in. 3 or 216 in. 3..

The length and the width of a rectangle are 10 cm and 5 cm respectively. A similar rectangle is formed by tripling the dimensions of the original one. What will happen to the perimeter of the new rectangle? => becomes four times the perimeter of the original rectangle or becomes..

A farmer has 2000 meters of fencing and wanted to fence a rectangular field used for livestock that borders his house on one side. He needs no fencing along his house. What will be the dimensions of the field if the area is to be largest? => 200 m and 100 m or 1000 m and 500 m o..
