On Saturday, Erin rode her bike to visit Caroline. Caroline's house is directly [E] of Erin's. The
graph shows how far Erin was from her house
after each minute of her trip.
a. Erin rode at a constant speed for the 1600
first 4 minutes of her trip. What was this
speed? 30
Distance (m)
800 +
b. What was Erin's average speed for
the whole trip?
0 1
2
8 9 10
3 4 5 6 7
Time (min.)
c. What was her average velocity?

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.

Which statement correctly describes the current in a circuit that is made up of any two resistors connected in parallel with a battery? a. the current in the battery and in each resistor is the same b. the current the battery equals to the sum of the currents in the resistors c. the current in the battery is less than the current in either resistor d. the current in the battery equals to the product of the currents in the resistors
