PHYSICS 2

2. It has a mass of 1.675 x 10-27kg
4. He determined that penicillin had an antibacterial effect on staphylococci and other gram-positive pathogens.
5. Switching direction back and forth
7. During the mid-18th century, electricity was already a well-known phenomenon. However, there were disagreements over the nature of this phenomenon.
8. It is an electric current flowing in one direction only.
15. It has a mass of 1.673 x 10-27kg.
17. It is a Parallel motion, back and forth motion.
18. State the rotation across a conductor is directly proportional to the current having through it, propelled I prompted all physical entities) the temperature remains constant.
20. It refers to the traveling pattern of motion exhibited by a wave, combining both oscillatory motion and forward motion.
21. Light travels in straight light until the light strikes an object, then it can reflect, refract absorb and
23. It receives signals.
25. Detects a small amount of current in the circuit.

1. Two waves interact/have an intersection pattern.
3. The displacement of the crest to crest/ Trough to Trough
6. It has a mass of 9.109 x 10-31kg.
9. It is a shift in the direction of a wavefront at the interface of two distinct media, causing the wavefront to return to the medium from which it came.
10. proposed the Corpuscular theory.
11. The bending of light (it also happens with sound, water, and other waves) as it passes from one transparent substance into another.
12. The highest point in the wave train
13. It is the gravitational force acting between two bodies of unit mass, kept at a unit distance from each other.
14. He proposed that light waves were transverse (vibrating at right angles to the direction of travel), rather than longitudinal (vibrating in the direction of travel).
16. It’s a bending of a wave as it passes on a barrier with an obstacle.
19. Force of attraction/repulsion of the two electrically charged parts is directly proportional to the product of magnitudes of ho charge and inversely prophetical to the square of the distance between the change.
22. He proposed the wave theory of light
24. equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.
