Gaaffii 1
Which discovery was proved in 2016 by LIGO?
Deebii: A Gravitational waves
Sababa
The chapter says Albert Einstein's idea about gravity as a wave was formulated in 1916 and was proved to be right in 2016 by LIGO. That idea is about gravitational waves.
Gaaffii 2
In which city is the Ethiopian Science and Art Museum located?
Deebii: B Addis Ababa
Sababa
The chapter says the Ethiopian Science and Art Museum is situated in Addis Ababa. It was inaugurated by PM Abiy Ahmed on 4 October 2022.
Gaaffii 3
Which of these is not one of the four main ways of acquiring experiential knowledge?
Deebii: D Mathematical and logical truths
Sababa
The four main ways of experiential knowledge are sensory perception, introspection, memory and testimony. Mathematics and logic are examples of non-experiential (a priori) knowledge, so they are not in this list.
Gaaffii 4
Which of these is a medical imaging method named in the chapter?
Deebii: D Magnetic resonance imaging (MRI)
Sababa
The chapter lists computer tomography, magnetic resonance imaging, positron emission tomography, ultrasonic imaging and laser surgery as medical applications of physics. GPS, bar code scanners and semiconductors are everyday objects, not medical imaging methods.
Gaaffii 5
The table shows the boiling point of water at different altitudes. At 150 m, water boils at 99.5 °C. At 1524 m, water boils at 95 °C. By how many degrees Celsius is the boiling point lower at 1524 m than at 150 m?
Deebii: B 4.5 °C
Sababa
Subtract the two boiling points: 99.5 °C minus 95 °C equals 4.5 °C. The boiling point is lower at the higher altitude, as the chapter's table shows.
Gaaffii 6
In the boiling water example, the student heated water at different altitudes and recorded the boiling temperature. Which step of the scientific method is this?
Deebii: C Experiment
Sababa
The chapter lists the steps as observation, question, research, hypothesis, experiment, analysis and conclusion. Heating water at different altitudes and recording the results is the experiment step.
Gaaffii 7
Physicists in healthcare work alongside biomedical engineers. Which healthcare area is reserved for people with an additional medical degree?
Deebii: A Cardiology
Sababa
The chapter says that cardiology and neurology are areas reserved for those with an additional medical degree. Physicists are regularly employed in radiology, radiation oncology and nuclear medicine.
Gaaffii 8
Which organization was established by Ethiopian physics professionals to enhance physics research and education in Ethiopia?
Deebii: D Ethiopian Physical Society (EPS)
Sababa
The chapter says the Ethiopian Physical Society (EPS) was established by Ethiopian physics professionals to enhance physics research and education, which helps the country's overall development. EPSNA works with Ethiopians in Ethiopia and North America, and aaps is a student-run association.
Gaaffii 9
Albert Einstein's hypothesis about gravity as a wave was formulated in 1916. It was proved to be right in 2016. How many years passed between the hypothesis and the proof?
Deebii: C 100 years
Sababa
Subtract the years: 2016 minus 1916 equals 100 years. The chapter says the proof took even more years, and it needed the work of thousands of scientists.
Gaaffii 10
As of 1 October 2022, there were 5,197 confirmed exoplanets in 3,833 planetary systems. About how many confirmed exoplanets were there per planetary system?
Deebii: B 1.4
Sababa
Divide the number of exoplanets by the number of planetary systems: 5,197 divided by 3,833 is about 1.36, which is about 1.4. Option D is wrong because it divides by 1,000 and does not use the number of systems.
