Professor of Anthropology Bruce Hardy makes headlines for his study on the cognitive abilities of Neanderthals. Kenyon alumni working in food and drink industries are sharing their go-to happy hour pairings.

But it will cause The frictional force between tyres of wear and tear of the tyres of the wheel. The normal reaction N can be resolved required for circular motion of vehicle. The maximum safety speed of a ix. It also depends on the angle x. Comparing equation vi and vii it is through which road is banked.

At this speed, the frictional force is not ii. There will be a little wear and tear path. Define angle of banking. Obtain an xii. What will happen for vehicle Q. The curved horizontal road is banked at xiii. Equation ix represents angle of banking of a banked road. Thus angle of banking is independent of mass of the vehicle. Write the necessary road surface. Define conical pendulum. Obtain an v. The tension T acting in the string can expression for the angle made by the string be resolved into two components: of conical pendulum with vertical.

Hence a. Ans: Definition: vi. Consider a bob of mass m tied to one v2 …. During the motion, string is inclined to This is the expression for the linear speed of the figure.

The weight mg acting vertically rh downwards. The tension T acting upward g along the string. Chapter Circular Motion ii. If the period of conical pendulum is T ii. In the displaced position P, there are two forces acting on the bob: Q. Discuss the factors on which time period of a. The weight mg acting vertically conical pendulum depends. The tension T acting upwards along the string. Acceleration due to gravity g : Time ….

Dividing equation ii by i , iii. Let a body of mass m be tied at the end of a massless inextensible string and This is required expression for tension in the whirled in a vertical circle of radius r in string.

At any point P the forces acting on it Q. Is there any limitation on semivertical are: angle in conical pendulum? For a conical pendulum, a. Weight mg along vertically downward direction. For b. H of string, and a body tied to a string vH cannot be resolved in a horizontal circle TH T vM H such that the string is horizontal. What is vertical circular motion? Show L vL mg that motion of an object revolving in vertical circle is non uniform circular motion. To complete vertical circular path, the Ans: i.

Consider an object of mass m tied at one …. Chapter Circular Motion v. When body is at highest position, Q. Velocity at lowest position: From equation ii , iii and iv it is observed According to law of conservation of that tension is maximum at lowest position energy, and minimum at highest position.

Derive an expression for the minimum. P is any point on the circle From equation iii as shown in the figure. More by ajzack. Electromagnetic Induction. You must be logged in to reply to this topic.

Such patterns are also observed in our day-to-day life. Definition of Sequence: A sequence is a collection of numbers arranged in a definite order according to some definite rule.

The number in the first position is called the first term and is denoted by t1. The number in the second position is called the second term and is denoted by t2. If tn is given, then a sequence can be formed. Finite Sequence: If the number of terms in a sequence is finite countable i. Infinite Sequence: If the number of terms in a sequence is infinite uncountable i.

The elements of a sequence are in a specific order, so they cannot be rearranged. The same value can appear many times. Set Elements are at random, so they can be rearranged. Any value can appear only once. The given sequence is 1, 2, 4, 7, 11, The given sequence is 0. The common ratio of two consecutive terms is 0. Solution: i. Find the first three terms of the sequences for which Sn is given below: [2 marks each] i.

Definition: A progression is a special type of sequence in which the relationship between any two consecutive terms is the same. Explain why? Types of Progressions: There are three types of progressions: i. Arithmetic progression A.

Geometric progression G. Harmonic progression H.
