Which is true about forces? Check all correct answers.
a. Forces are scalar quantities-they do not need direction.
b. Force is directly proportional to acceleration and mass. Objects with bigger mass and higher acceleration can produce bigger forces.
c. Forces are vectors- they always have magnitude and direction.
d. Objects at rest do not have any force acting on them.
e. Gravity only acts on objects that are falling.
f. Forces always require the Agent and the Receiver to touch to take effect.
g. Forces of equal magnitude but in opposite directions have a zero net force and so are in a balanced state- at rest or in motion.

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
