A becquerel (Bq) is defined as:

• The activity of a quantity of radioactive material in which one nucleus decays per second

• The energy released by a sample of radioactive each second

• The mass of decaying atoms in a sample of radioactive substance

• The number of atoms in one mole of substance

Convert 1 gigawatt (GW) to watts.

• 1,000 watts

• 10,000 watts

• 1,000,000 watts

• 1,000,000,000 watts

The difference between absorb and transmit in the context of light is:

• Absorb means to take in light, while transmit means to let light pass through.

• Absorb means to reflect light, while transmit means to block light.

• Absorb means to scatter light, while transmit means to focus light.

• Absorb means to increase light, while transmit means to decrease light.

Accurate in scientific measurements means:

• The measurement is close to the true value.

• The measurement is repeated several times.

• The measurement is done quickly.

• The measurement uses advanced instruments.

An alpha particle is made up of...

• Two protons and two neutrons

• One proton and one neutron

• Two electrons and two protons

• One electron and one neutron

Amplitude in a wave can be measured as:

• The distance from the rest position to the crest or trough

• The total length of the wave in the medium

• The number of waves passing a point per second

• The speed at which the wave travels

The relationship between the angle of incidence and angle of reflection is:

• They are always equal.

• Angle of incidence is greater than angle of reflection.

• Angle of reflection is greater than angle of incidence.

• There is no predictable relationship between them.

An anomalous result in an experiment is caused by:

• a mistake or error during the experiment

• a correct measurement

• following the method accurately

• using precise equipment

Atomic number is defined as:

• The number of protons in an atom

• The number of neutrons in an atom

• The sum of protons and neutrons in an atom

• The number of electrons in an atom

How is background count detected using a Geiger-Müller (G-M) tube?

• By measuring the count rate in the absence of a radioactive source

• By increasing the voltage across the tube

• By placing a strong radioactive source near the tube

• By shielding the tube completely from all radiation
