ABCTE- PHYSICS EXAM QUESTIONS
& ANSWERS
Data - Correct Answers -The measurements and numbers collected during an
experimental process based on which a conclusion may be arrived at are called
Derived - Correct Answers -The unit of speed, m/s, is an example of a ______ unit
making an observation - Correct Answers -The first step of the scientific method
involves ___________
Inversere - Correct Answers -Which type of relationship is shown by the following
graph?
Slope is 1.8 and y-intercept is 32 - Correct Answers -Identify the slope and y-intercept of
the equation:
Fahrenheit Temperature = (1.8 °F/°C)(Celsius Temperature) + 32 °F
6.40 m - Correct Answers -If 1 inch = 2.54 cm and 1 yd = 36 in, how many meters are in
7.00 yd?
Look for negative exponents - Correct Answers -Which of the following has the smallest
value when expressed in proper scientific notation?
What is the configuration of an elliptical galaxy? - Correct Answers -An elliptical galaxy
is a galaxy without spiral arms and with spherical — or egg—shape.
Long, because they consume fuel (mass) at a very slow rate - Correct Answers -Stars
with a relatively small mass have what type of lifespan compared to more massive stars
, That's because its molar mass is the smallest of the group. Since all the molar masses
are divided into the same number, 110 g, the one with the smallest molar mass will
contain the greatest number of moles. - Correct Answers -Which substance would have
the greatest number of moles in a 110 g sample
The acceleration is too small - Correct Answers -The Earth turns on its axis once every
day with all of us riding on it like passengers on a carousel. Our speed is more than 400
m/s. Which of the following BEST explains why we don't notice this speed and get
dizzy?
40 meters-we use vf = at + vi to determine the acceleration which comes out as 5 m/s2.
Then we use x = ½at2 + vit to determine x, which turns out to be 40 m - Correct
Answers -A car starts at rest at a red light and reaches 20 m/s in 4 seconds. How far
has the car traveled?
Newton's First Law applies to all objects, no matter what those objects are doing at the
moment. - Correct Answers -Inertia applies to______________________
It accelerates - Correct Answers -A ball is dropped from 5 m high and falls towards the
earth. There must be a net force acting on the ball because_____________________
— 7.35 m/s2.... The only force acting to stop the car is friction, so
—Ff = ma
Then:
—μmg = ma —μg = a
The car is not free falling at 9.8 m/s2, the 20 m/s is the car's velocity, and the
acceleration needs to be negative because the car's velocity is decreasing. - Correct
Answers -A 2000 kg car moving at 20 m/s stops for a red light. The coefficient of friction
between the tires and the road is 0.75. What is the car's acceleration while stopping?
Fg - Fn = mac
490 - Fn = 100
Fn = 390 N - Correct Answers -A 50 kg passenger on a roller coaster goes over the top
of a hill that has a 50 m radius at 10 m/s. What is the passenger's apparent weight?
7.81 J ..Energy gets stored in the spring, so work must be done. 62.5 is the force in
Newtons. The correct answer comes simply from solving Es = (1/2)kx2.. - Correct
Answers -A spring with a constant of 250 N/m rests horizontally on a frictionless table,
with one end resting against a wall. A 5 kg block is pressed against the spring,
compressing it .25 m from equilibrium.
How much work is done compressing the spring?
3.12 m/s ...The Es turns into Ek so
Ek = (1/2)kx2 = 7.81 J
7.81 = (1/2)(5)v2
