Q1. A galvanometer with a coil resistance of 11.0 and the full-scale current of 0.150 mA is used with a shunt resistor to make an ammeter. The ammeter registers the maximum current of 4.00 mA. Find the equivalent resistance of the ammeter.

Q2. Chair of weight 95.0 lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of = 38.0 directed at the angle of 34.0below the horizontal and the chair slides along the floor.

Using Newton's laws, compute the magnitude of the normal force that the floor exerts on the chair.
