Answer:
15.Radiowave
16.laser is device that generates an intense beam of other electromagnetic radiation by emission of photons from excited atoms.
17.this is a laboratory instrument commonly used to display and analyse the waveformof electronic signals.
19. this is a space entirely devoid of matter.
1b) the atom could lose its valence electron
c) protons are equal to electrons so there is no need to include it
d) the atom would need to gain electrons to fill its valence shell to become negative
Answer:
high accuracy low precision.
Explanation:
Answer: Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +.
