C. d. fixed and movable . Ed * Ld = ExL iv. MA x E = MA x L The lever which makes our work easier only by accelerating the rate 7. third class lever. ii. second class lever. iii. first class lever having effort distance equal to load distance iv. first class lever having more effort distance. Differentiate between: a mechanical advantage and velocity ratio b. velocity ratio and e second class lever and third class lever Give reason a Value of MA is always lesser than VR b. Efficiency of a lever is never 100% or more. c. A tight knot can be easily opened by using a long spanner d. The handles of tin-snips (metal cutter) are made long. e. Output work is always less than input work. f. The value of MA in the third class lever is always less than one. A second class lever needs less effort to lift a heavy load. 7. The blade of a metal cutter is shorter than that of the scissors use It will be easier to lift a load in a wheelbarrow if the load is towards the wheel. Answer the following questions. How does a simple machine facilitate our work? : Show the relation among MA, VR and n. What are MA and VR of a lever? How does a second class lever make our work easier? What is a lever? Also mention its types? Define efficiency of a lever. What is meant by efficiency of a machi A strong person and a weak person are trying to carry a ladder. H they carry it in such a way that the weak person feels less weight of What do you mean by MA of a lever is 3, VR of a lever is 4 machine is 60%? grammatic Questions: Answer the following questions on the basis of the given diagrar forron m appi​

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i. e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i. e. include the distance traveled to the first encounter)
