What is the direction of the frictional force? what is the direction of the normal force? how does the frictional force depend on the normal force? let the x-axis be parallel to the incline and the y-axis rise from the incline at a right angle. by newton's second law, if there is no acceleration in the y-direction (perpendicular to the plane), what must be the magnitude of the normal force? use newton's second law and the x-components of the forces to find the acceleration. m/s2

What is the direction of the frictional force?

Direction of friction is always opposite to relative motion

Explanation:

Friction always resist the relative motion of two surface so it is always opposite to the direction of relative velocity

What is the direction of the normal force?

It is perpendicular to the contact plane

Explanation:

Normal force is the perpendicular force which is always at 90 degree with the contact surface

How does the frictional force depend on the normal force?

Explanation:

Friction force is directly proportional to the normal force so we can say it is given as

Let the x-axis be parallel to the incline and the y-axis rise from the incline at a right angle. By Newton's second law, if there is no acceleration in the y-direction (perpendicular to the plane), what must be the magnitude of the normal force?

Explanation:

Normal force is equal to the component of the weight opposite to the direction of normal force

Use Newton's second law and the x-components of the forces to find the acceleration. m/s2

Explanation:

As we know that

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
