Two wagons of equal mass are filled with an equal mass of bricks. person a pushes one wagon with twice the force that person b pushes the second wagon.

how is the acceleration affected?

a.
person a's wagon will accelerate at twice the rate of person b"s wagon.

b.
person a's wagon will accelerate at 1/2 the rate of person b's wagon.

c.
both wagons will accelerate at the same rate, since the mass is the same.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.

The amount of potential energy possessed by an elevated object is equal to what?

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.
