Due date 25 September 2024 Electricity and
Magnetism
Laptop computers are made with batteries, but they must also be
plugged into outlets to charge the batteries. Which is true regarding
laptops? - ANS-They can run on either direct or alternating current.
What is the function of an electromagnet in an electric doorbell? -
ANS-It attracts a metal striker, which then hits the bell.
What causes the poles of the electromagnet in an audio speaker to
repeatedly switch directions? - ANS-a current that rapidly switches
direction
How does increasing the distance between charged objects affect
the electric force between them? - ANS-The electric force
decreases because the distance has an indirect relationship to the
force.
How does increasing the amount of charge on an object affect the
electric force it exerts on another charged object? - ANS-The
electric force increases because the amount of charge has a direct
relationship to the force.
For which pair of objects would adding the same amount of
electrons to each object result in a decrease in the electric force? -
ANS-two positively charged objects
, Which factors affect the strength of the electric force between two
objects? - ANS-the distance between the objects and the amount of
charge on the objects
Measurements of two electric currents are shown in the chart.
Which best compares the two currents? - ANS-Current Y has a
greater potential difference, and the charges flow at a slower rate.
Two balls are placed near one another and hang down, as shown
below.
Which conclusion is supported by this evidence? - ANS-Neither ball
has a charge.
As Chelsea removes her clothes from the dryer, she sees sparks,
which are examples of . - ANS-static discharge
The area around a charged object where the object can exert a force
on other charged objects is an electric . - ANS-field
An electroscope is a device that detects charge on objects that
touch it or are brought near it. John rubs a piece of cotton fabric on a
plastic rod and then touches the rod to the electroscope.
What methods of charging does John use? - ANS-John charges the
rod through friction, then charges the electroscope through
conduction
Which change increases the electric force between objects? - ANS-
Electrons are added to two negatively charged objects.
