A car is rounding a circular curve of radius r on a banked turn. As the drawing indicates, there are two forces acting on the car, its weight mg and the normal force FN exerted on it by the road. Which force, or force component, provides the centripetal force that keeps the car moving on the circular path?
1. The vertical component, FNcosθ of the normal force.
2. The horizontal component, FNsinθ of the normal force.
3. Both the normal force, FN, and the weight, mg, of the car.
4. The normal force, FN.
5. The weight, mg, of the car.
6. The horizontal component, FNsinθ of the norma. l

Explanation

Centripetal force is a net force that acts on an object to keep it moving along a circular path.

It is given as

F=ma

Where a =v²/r

F=mv²/r

The centripetal force is directed towards the center i.e inward.

Then, analysing the free body diagram, we notice that the horizontal component of the Normal force (FNsinθ) is directed towards the centre. Then, we can say the last option 6 is correct.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
