Answer:
b. The horizontal component of the normal force acts toward the center of the circle.
Explanation:
When a car on a banked turn move with just the right speed so that the frictional force is zero, a component of the normal force -which is always perpendicular to the surface- acts as the centripetal force on the car. This is because the normal force now has a horizontal component, and this component supplies the centripetal force.
Our Atmosphere is full of freely subtended particles, and when light from sun strikes the particles then scattering occurs, in which blue colour is most scattered and hence causing Sky to appear blue .

'Gram', 'kilogram', and 'metric ton' are units of mass, not weight.
'Pound' can be either a unit of mass or of force. Most people
use it most of the time to mean weight.
Force is a push or a pull of an object that causes the object to speed up, slow down, or stay in one place. In other words, a force is what causes an object to move. Friction and gravity are two types of forces that influence how an object moves.
