Question 37. You can configure some bits of a Ribbon client by using external properties in .ribbon. Name the force which increases when the two surfaces in contact are made more rough. Lubrication means applying some additive to the parts of a machine to reduce the friction. Question 54. The tyre’s surface has treads on it. A. trimlined shape Answer: 1. Friction do not produce heat. Answer: The friction is produced due to the contact of the two surfaces of the table and the book. D. Sliding, Static, Rolling 13. A spring balance measures force. Question 42. Answer: Which will cause more friction: a rough surface or a smooth surface? What is the direction of force of friction acting on a moving object ? What is done to increase friction between the tyres and road? The spring balance is a device which is used for measuring force acting on an object.The spring balance contains a coiled spring which gets stretched when a force is applied to its free end.The extent by which the spring get stretched is a measure of force applied. Spring Cloud has created an embedded Zuul proxy to ease the development of a common use case where a UI application wants to make proxy calls to one or more back end services. Answer: The static friction > Sliding Friction > Rolling friction. API Doc. Answer: At this price level and power, a pure class-A output stage is out of the question; the CA-200 runs fairly cool in class-A/B, enjoying an economical level of idle power. b.

Table of content: 1. Answer: Frictional forces prevent us from slipping every time you take a step forward. 12. Answer: Different load balancing algorithms provide different benefits; the choice of load balancing method depends on your needs: 1. Why is it difficult to walk on a wet marble floor? Study the spring balance, its scale and its least count. What is the cause of friction? A speedboat has a streamlined shape so as to reduce the fluid friction as it moves in the waters. Answer: v) ----- can be used to reduce friction. Example of @Autowired Annotation. Question 68 B. (c) Friction produces…………….

The special shape is more like a point shaped so that they cut the fluid friction. D. it enables vehicles to move on ground The reading on the scale gives the magnitude of the force. By studying the Newton spring balance we may appreciate the way in which the law works and how to use it to measure force. Question 8 Give example to show that friction depends on the nature of two surface in contact? Question 74. (j) Objects which can move quickly through the water have a streamlined shape. Where does this force act? Question 53. Then, in this case he will have to apply more force to overcome the larger friction as in the earlier case.

The @Bean annotation tells Spring that a method annotated with @Bean will return an object that should be registered as a bean in the Spring application context. Heavier the mass, more the force is exerted by the object on the surface and thus more friction is produced. Why? tulsi says: February 6, 2016 at 8:20 am.
