Phys 1010 final Exam Questions with Correct
Answers
When a gas is forced into half of its original volume without
change in temperature,
(A)
the pressure becomes one quarter of the original pressure.
(B)
the pressure is the same as the original pressure.
(C)
the pressure quadruples.

,A passenger jet airplane takes off at an airport and reaches a
cruising altitude of 15 km above the ground. When the airplane
reaches the cruising altitude, the ho
rizontal distance between the
airplane and the airport is 20 km. What is the displacement of
the airplane from the airport when the airplane reaches the
cruising altitude (the actual distance between the take
-
off point
and the point where the airplane reac
hes the cruising altitude)? 25 km
A car has traveled 50 km in 30 minutes. The car's average speed

8 m wide, and 2.5 m high has a m
ass of 130 kg
The acceleration of an object moving in a circle at constant
speed is
(A)
toward the center of the circle.
(B)
in the direction of the object's motion.
(C)
zero because the spe
ed is constant.
(D)
away from the center of the circle.
, (E)
in the opposite direction of the object's motion toward the center of the circle.
