A woman does pushups by lowering her body to the floor using her
arms and then pressing against the floor with her hands to push herself
back up, as shown in the image below. Which force causes her to rise? -
ANSWER->The upward force that the ground exerts on the woman
Two boxes sitting on the floor look identical, but one has more mass
than the other. What happens when the same net force, sufficient to
overcome static friction, is applied to each box? - ANSWER->The box
with less mass accelerates more.
Two identical train engines are parked on parallel tracks. One engine
has ten cars attached, and the other has no cars attached. Each engine
exerts the same net force, which allows the train to overcome static
friction. Which engine will be able to accelerate more? - ANSWER->The
engine not pulling any cars will accelerate more.
A woman applies an upward force to a basket filled with groceries.
Assume she is standing still.
What will happen to the basket if the force she applies is greater than
the force of gravity? - ANSWER->The basket will move up.
A heavy truck and a light car travel at the same velocity side-byside on
the highway. Both drivers apply the same braking force at the same
moment.
What will happen to the two vehicles? - ANSWER->The car will slow
down more quickly than the truck.
,Which force causes graphite from the tip of a pencil to transfer to the
paper? - ANSWER->Friction
Which force keeps Jupiter in orbit around the Sun? - ANSWER>Gravity
Which force causes a jet airplane to stop on a runway? - ANSWER-
>Friction
Which force causes meteors to burn up when they enter Earth's
atmosphere? - ANSWER->Friction
Which kind of electromagnetic radiation carries information to
and from a cell phone when it is used for a phone call? - ANSWER-
>Microwaves
A cashier who has been handed a hundred-dollar bill may check its
authenticity by holding it under a special lamp that emits
electromagnetic radiation mostly at wavelengths slightly shorter than
visible light. The electromagnetic radiation makes a pattern of
previously invisible markings on the bill glow brightly, or fluoresce.
Which kind of electromagnetic radiation does the lamp emit to produce
this effect? - ANSWER>Ultraviolet Radiation
After natural disasters, first responders can locate survivors in the
rubble by using thermal detectors. Because the victims' bodies are
warmer than their surroundings, the difference in temperature is
detected by electromagnetic waves. Which part of the electromagnetic
spectrum is being detected? - ANSWER>Infrared radiation
, Airport security uses electromagnetic radiation to form images of
objects inside passenger luggage. Which type of electromagnetic
radiation is used in this way? - ANSWER->X-
Rays
Which type of wave has a longitudinal motion? - ANSWER>Sound waves
Which is a characteristic of electromagnetic waves? -
ANSWER>Transverse wave motion
A slingshot is a Y-shaped stick with rubber bands between the prongs
for shooting stones and other small projectiles. A stone is shot by first
placing it in the slingshot holder, which is attached to the rubber bands.
The stone and holder and then pulled back, stretching the rubber
bands. When released, the stone is propelled forward and leaves the
slingshot at a high speed. Which type of energy transformation occurs
from the point when the rubber bands are fully stretched to when the
stone leaves the slingshot? - ANSWER->Elastic potential energy is
converted into kinetic energy.
Which type of energy conversion occurs at the moment fireworks
explode? - ANSWER->Chemical potential energy is converted into
kinetic energy.
What energy conversion takes place as a box slides to a stop on a
horizontal table? - ANSWER->Chemical potential energy is converted
into thermal energy.
Which action demonstrates a chemical change? - ANSWER>cooking an
egg
