9. Three capacitors are arranged in series. If C₁ = 14 μF, C₂= 16 μF and C3= 22 µF then what is the equivalent capacitance? 10. What would be the equivalent capacitance if the capacitors were arranged in parallel?

At an accident scene on a level road, investigators measure a car’s skid mark to be 112 m long.  It was a rainy day and the coefficient of friction was estimated to be 0.42.  Use these data to determine the speed of the car when the driver slammed on (and locked) the brakes.

A girl weighing 45kg is standing on the floor, exerting a downward force of 200N on the floor. The force exerted on her by the floor is

Calculate P required to move block A upward. Assume the coefficient of friction is 0.2 below block B. Neglect friction at all other contact surfaces. 30° P B 80 lb H₂ = 0.2 A 120 lb

If an object is on an inclined plane having an angle e, what is the component of weight (w) parallel to incline?

At an accident scene on a level road, investigators measure a car's skid mark to be 89 m long. It was a rainy day and the coefficient of friction was estimated to be 0.43. Use these data to determine the speed of the car when the driver slammed on (and locked) the brakes.

ma tug-of-war game on one campus, 15 students pull on a rope at both ends in an effort to displace the central knot to one side or the other. Two students pull with force 196 N each to the right, four students pull with force 87 N each to the left, five students pull with force 62 N each to the left, three students pull with force 150 N each to the right, and one student pulls with force 250 N to the left. Assuming the positive direction to the right, express the net pull on the knot in terms of the unit vector. How big is the net pull on the knot? In what direction? net pull N to the Select an answer v %3D TA 8088 ni pnibne inu

In the friction experiment, if the friction block has a mass of 599 g, and it started to move at a constant speed after giving it a slight push when the mass in the hanger is 284 g (including the hanger), what is the coefficient of kinetic friction?

A 22-kg crate is on an incline that makes an angle of 30° with the horizontal. If the coefficient of static friction is 0.50, the minimum force that can be applied parallel to the plane to hold the crate at rest is:
