PHY112 RIO SALADO - QUIZ 3 Questions With Complete
Solutions
A 1.5V battery connects to a 10 Ω resistor. The power dissipated
by the resistor is Correct Answers 0.23 W
A 9.0V battery connects to a wire resistor. The wire resistor is
tungsten (ρ = 5.6 x 10-8 Ω-m) 0.5 m long, has a radius of 1.2 x
10-5 m. What is the current through the resistor? Correct
Answers 0.15 A
A battery connects to a resistor with resistance R, and the
resulting current is measured. The resistor is removed, and a
new resistor with a resistance of 2R is added. As a result,
Correct Answers None of the above options are correct.
A battery connects to a resistor. The rate of energy dissipated by
the resistor is 1.44 W. The rate of energy supplied by the battery
is Correct Answers equal to 1.44 W.
A battery with a potential difference of V connects to a resistor,
and the resulting current is measured. You remove the battery,
and a new battery with a potential difference of 2V is put in its
place. As a result, Correct Answers the current will double.
A particle with a mass of 0.01 kg and a net charge of -0.05 C
accelerates from rest through a uniform electric field. If the
strength of the field is 2000 V/C, what is the speed of the
particle after traveling for 0.5 m? Correct Answers 100 m/s
