What is the normal force acting on a 10kg box if it is on a flat frictionless surface being pushed with a horizontal foce of 20N?

A 15kg block rests on a 29 degree inclined frictionless surface and is attached by a light string to a 36kg hanging mass where the string passes over a massless frictionless pully. What is the tension in the connecting string? Gravity is 9.8ms and please round to 3 decimal places.

A 55 kg box is sitting on a rubber conveyor belt. The friction angle is reported to be 38o, what is the maximum acceleration the belt can have to avoid having the box slip along the conveyor?
