Urgent Physics Questions: Help Needed for Assignment Due Tomorrow

[Melrose<3]

Urgent Physics Question++++!

Can someone please help me answer these questions for physics? I need them urgently for an assignment that is due tomorrow.

1.) A person is trying to judge if a picture (mass = 1.10kg) is properly positioned by pressing it against a wall. The pressing force is perpendicular to the wall. The coefficient of static friction between the picture and the wall is 0.660. What is the minimum amount of pressing force that may be used?

2.) Saturn has an eqyatorial radius of 6.00 x 10^7m and a mass of 5.67 x 10^26
Calculate the following:
a.) the acceleration due to gravity of Saturn
b.) how many times greater is a person's weight on Saturn compared to that on
Earth?

3.) A block with a weight of 455 N is being pulled at constant velocity by a force directed at 30 degrees above the horizontal. The frictional force on the crate is 1163N. What is the magnitude of the pulling force?

SOMEONE PLEASE HELP ME! PLEASE! I HAVE NO CLUE ON HOW TO START AND DO THESE QUESTIONS. Thanks.

Welcome to PF, Melrose.
Please pay attention to the posting guidelines. This belongs in the homework section, and nobody here will do your work for you. It's up to you to show what you've done already and ask specific questions as to your procedures.
As to the Saturn question, it's just plain stupid. Saturn is a gas giant planet. We don't (as far as I've learned) know where the theoretical solid surface is. You have to be on a surface for weight to be measured. If the question means what would be your apparent weight if you were on a solid surface at 6 x 10^7m from the core of the planet, that's a different matter.
