A car moves at a constant speed on a straigh but hilly road. One section has a crest and dip of the 250m radius. (a) As the car passes over the crest the normal force on the car is half the 16kN weight of the car. What will the noraml force on the car its passes through th ebottom of the dip? (b) What is the greatest speed at which the car can move without leaving the road at the top of the hill ? (c) Moving at a speed found in part (b) what will be the normal force on the car as it moves through the bottom of the dip? (Take, g=10m//s^(2))

Statements given below are incorrect. Write the correct statements: The force of attraction between similar kind of molecules is called force of adhesion.

When Neils Bohr shook hand with Werner Heisenber, what kind of force they exerted?

A box of bananas weighing 40.0N rests on a horizontal surface is 0.40 and the coefficient of kinetic friction is 0.20 a. If no horizontal force is applied to the box and the box is at rest , how large is the friction force excered on the box ? b. What is the magnitude of the friction forces if a monkey applies a horizontal force of 6.0 N to the box and the box is initial at rest? c. What minimum horizontal force must the monkey apply to start the box in motion ? d. What minimum horizontal force must the monkey apply to keep the box moving at constant velocity once it has been starts? e. If the monkey applies a horizontal force of 18.0N What is the magnitude of the friction force and what is the box's acceleration ?

(ii) Which force has the greatest moment about O? Give reason. (iii) Name the forces producing (a) clockwise , (b) anticlockwise moments. (iv) What is the resultant torque about the point O?

This question has statement 1 and statement 2 . Of the four choice given after the Statement , choose the one that best describe the two Statement . If the spring S_(1) and S_(2) of force constant k_(1) and k_(2) respectively , are streached by the same force , it is found that more work is done on spring S_(1) then on spring S_(2) Statement -1: If statement by the same answer work done on S_(1) work on S_(1) is more then S_(2) Statement - 2 : k_(1) ltk_(2)

When an elastic object , such as a coil spring or rubber band, is subjected to a force f, an increase in length , called a strain , occurs . Hooke's law states that force f is directly porportional to strain s. Suppose that a coil spring has a natural length of 4 feet and that a force of 60 pounds stretches the length to 6 feet. What magnitude of force , in pounds , would stretch the spring to a length of 7 feet ?
