MULTIPLE CHOICE 1-5 ONLYY

SELF-PACED LEARNING MODULE IN GENERAL PHYSICS 2 (GRADE 12 STEM ONLY) Code #: Grade & Section: Name: Name of Teacher: Mary Angelic C. Canalija Score: FA - SA - QTR. 4- MODULE 3: PHOTOELECTRIC EFFECT & RADIOACTIVE DECAY Module Overview: All matter is made up of atoms. Our knowledge of atoms made us understand the basic properties of the states of matter solid, liquid and gas. And going deeper in studying its subatomic particles, using the concept of nuclear atom which is composed o the electrons around the nucleus and the particles inside the nucleus, the protons and neutrons, opens the fundamental basis of the modern view of the world. This module demonstrates your understanding on the concepts of Atomic and Nuclear Phenomena and how Scientists were able to explain it using the particle-like behavior of light. Learning Competencies: At the end of this module, you can: 1. Explain the photoelectric effect using the idea of light quanta or photons (STEM GP12MPIVH-45); and 2. Calculating radioisotope activity using the concept of half-life (STEM GP12MPIVH-i47). Instructional Materials: Ramos J., et al, 2016. Exploring Life Through Science. General Physics 2. PHOENIX PUBLISHING HOUSE, INC., 927 Quezon Avenue, Quezon City Values: Critical Thinking Pre-ass essment Directions: Carefully read each item. Write the letter of your answer on the answer sheet provided for you at the last page of this module. 1. Which of the following greatly contributes to the stopping potential of the photoelectrons? a. Frequency of incident light and nature of the cathode material b. The intensity of the incident light c. The frequency of the incident light d. Nature of cathode material 2. Who discovered the photoelectric phenomenon? b. Faraday c. Plank d. Hertz a. Einstein 3. All radioactive sources have a half-life. Which statement about the half-life of a source is correct? a. It is half the time for the radioactive source to become safe. b. It is half the time it takes for an atom to decay. c. It is half the time it takes the activity of the source to decrease to zero. d. It is the time it takes the activity of the source to decrease by half. 4. What do you call the minimum energy required to remove an electron? c. Work function 5. Radioactivity may be detected by which one of the following instruments? c. Ratemeter a. Stopping potential b. Kinetic energy d. None of these a. Atomic clock b. Geiger-Muller tube d.
