Question

Arnold Strongman and Suzie Small each pull very hard on opposite ends of a rope in a tug-of-war. the greater force on the rope is exerted by Arnold, of course. Suzie, surprisingly. both the same, interestingly. A pair of toy freight cars, one twice the mass of the other, fly apart when a compressed spring that joins them is released. The spring exerts the greater force on the lighter car. heavier car. same on each. What is the force of gravity on a 500-N woman standing on Earth's surface? 50 N 250 N 5000 N 500 N none of the above The force exerted on the tires of a car that directly accelerate it along a road is exerted by the tires. engine. road. air. none of the above The force responsible for a car moving steadily along a no-friction icy banked curve is due to the radial component of the normal force. centrifugal effects. the normal force at right angles to the curved surface. none of the above

Answer 1

Here

17)

both will apply same force according to Newton's third law

the correct option is C)

18)

as the spring force is , F = k * x

and this force is same on both the ends

hence , the correct option is c

19)

as the weight of woman = 500 N

force of gravity = 500 N

option D) 500 N

20) for the acceleration of car tyres ,

and the tires are in contact

the correct option is C) road
