Answer:
ans for A)
Ball A being negatively charged and Ball B being neutral
when they come into contact.... electrons from the ball A will transfer to ball B and since they are covered by an electrical conductor... their contact will form a joint pathway for electric charge to be transferred to another object.
If it makes 50 complete back-and-forth wiggles in 1 second, then its frequency is <em>50 Hz</em>.
Answer:
Explanation:
From the given information, the LED is operating with a given wavelength of 850 nm or 0.85 μm.
Hence, the material dispersion is
Now, using the pulse spread formula:
Thus, the pulse spreading as a result of material dispersion is:
Answer:
speed = wavelength * frequency
Explanation:
Thenks and mark me brainliest :)
