Phys 1260- Exam 2 Questions with
Answers 100% PASS
When two lamps are connected in series to a battery, the electrical resistance that
the battery "senses" is - CORRECT ANSWER-More than the resistance of either
lamp
When two lamps are connected in parallel to a battery, the electrical resistance that
the battery "senses" is - CORRECT ANSWER-Less than the resistance of either
lamp
When two identical lamps in a circuit are connected in parallel, the total resistance
is - CORRECT ANSWER-less than the resistance of either lamp.
Consider a lamp powered by a battery. Charge flows - CORRECT ANSWER-
through both the battery and the lamp
The direction of the force exerted on a moving charge in a magnetic field is -
CORRECT ANSWER-at right angles to the direction of the motion
, The force on an electron moving in a magnetic field will be least when its direction
is - CORRECT ANSWER-the same as the magnetic field direction
A beam of singly-charged ions entering a magnetic field are swept into circular
paths. The wider paths are those of - CORRECT ANSWER-the heavier ions
When current reverses direction in a wire, the surrounding magnetic field -
CORRECT ANSWER-also reverses direction
A weak and strong magnet repel each other. The greater repelling force is by the -
CORRECT ANSWER-both the same
The source of all magnetism is - CORRECT ANSWER-Both or either A and B
A. Electrons rotating around an atomic nucleus
B. Electrons spinning around internal axis
Where magnetic field lines are more dense, the field there is - CORRECT
ANSWER-stronger
An electromagnet can be made stronger by: - CORRECT ANSWER-Both A and
B
A. Increasing the number of turns of wire
B. Increasing the current in the coil
The reason that an electron moving in a magnetic field doesn't pick up speed is -
CORRECT ANSWER-The magnetic force is always perpendicular to its motion.
