Gaaffii 1

Which of the following is correct about the meaning of Photon?

A.quantum of matter
B.positively charged particle
C.negatively charged particle
D.quantum of light

Deebii fi ibsa ilaalaa

Deebii: D quantum of light

Maaliif

A photon is defined as the quantum of electromagnetic radiation or light, carrying energy proportional to its frequency but having zero rest mass.

Gaaffii 2

Consider a series RC circuit for which $R = 1.0\,\mathrm{M\Omega}$ , $C = 5\,\mu\mathrm{F}$ and $\varepsilon = 30\,\mathrm{V}$ . What is the time constant of the circuit and the maximum charge on the capacitor after the switch is closed respectively?

A.5 seconds, 150 $\Omega$ C
B.7 seconds, 155 $\Omega$ C
C.10 seconds, 160 $\Omega$ C
D.9 seconds, 135 Mc

Deebii fi ibsa ilaalaa

Deebii: A 5 seconds, 150 $\Omega$ C

Maaliif

The time constant is

\tau = RC = (1.0 \times 10^6\ \Omega)(5 \times 10^{-6}\ \text{F}) = 5\ \text{s}

. The maximum charge is

Q = C\varepsilon = 5\ \mu\text{F} \times 30\ \text{V} = 150\ \mu\text{C}

(where '

\Omega

' is a typo for '

\mu

').

Gaaffii 3

What is the direction with which a fish must push the water with its fins in order to propel eastward?

A.eastward
B.upward
C.westward
D.downward

Deebii fi ibsa ilaalaa

Deebii: C westward

Maaliif

According to Newton's third law of motion, every action has an equal and opposite reaction. To propel itself eastward, the fish must push the water westward.

Gaaffii 5

One person drops a ball from the top of a building while another person at the bottom observes its motion. The two people disagree on which of the following?

A.The value of the total energy of the ball.
B.The change in potential energy of the ball.
C.The value of the gravitational potential energy of the ball earth system.
D.The kinetic energy of the ball at some point in its motion if one of them is walking.

Deebii fi ibsa ilaalaa

Deebii: C The value of the gravitational potential energy of the ball earth system.

Maaliif

The gravitational potential energy depends on the choice of the reference level (where

U=0

). Since the two observers are at different heights, they will naturally choose different reference levels and thus disagree on the value of the potential energy, although they will agree on its change.

Gaaffii 6

Two non-zero vectors $\vec{A}$ and $\vec{B}$ are related by $\vec{A} = c\vec{B}$ where c is a scalar. If the two vectors have opposite directions, then one of the following is true about c?

A.c is a positive number
B.c is a negative number
C. $c = 1$
D. $c = 0$

Deebii fi ibsa ilaalaa

Deebii: B c is a negative number

Maaliif

If two vectors are related by

\vec{A} = c\vec{B}

and point in opposite directions, the scalar multiplier

c

must be negative to reverse the direction of

\vec{B}

Gaaffii 7

On which of the following does the induced emf in a coil NOT depend when a magnet is inserted into it?

A.resistance of the coil
B.number of turns of the coil
C.speed approach of the magnet
D.magnetic moment of the magnet

Deebii fi ibsa ilaalaa

Deebii: A resistance of the coil

Maaliif

According to Faraday's law of induction, the induced electromotive force depends on the number of turns and the rate of change of magnetic flux, but it is independent of the resistance of the coil (which only affects the induced current).
