A suspect is leading the police on a car chase. The officer reports that the suspect is traveling north at 100 miles per hour. The officer has reported the suspect's
Answers
In order to count velocity, you need speed and direction to define it.
the police just describe the speed (100 miles per hour) and the direction (to the north)
hope this helps

b. blue, yellow, and white are primary colors.
c. they are complementary colors of light.
d. they are both primary colors of light.
Answers
Answer: The correct answer is c.
Explanation: According the RGB color model, the light of the two complementary colors will combine to form a white light. This happens because the complementary colors combine at full intensity.
Complementary colors according to RBG color model is:
- Red - Cyan
- Green - Magenta
- Blue - Yellow
From the above information, we conclude that blue light and yellow light are complementary colors of light and hence, the combination of two will produce white light.
When you say complementary colors, it refers to a combination of 2 colors that when mixed, they fade out their color. That's why when blue light and yellow light are combined they produces white light.

Answer:
508Hz
Explanation:
A tuning fork with a frequency of 512 Hz is used to tune a violin. When played together, beats are heard with a frequency of 4 Hz. The string on the violin is tightened and when played again, the beats have a frequency of 2 Hz. The original frequency of the violin was ______.
When two sound waves of different frequency approach your ear, the alternating constructive and destructive interference causes the sound to be alternatively soft and loud - this phenomenon is beat production
frequency is the number of oscillation a wave makes in one seconds.
f1-f2=beats
therefore f1=512Hz
f2=?
beats=4Hz
512Hz-f2=4Hz
f2=512-4
f2=508Hz
the original frequency of the violin is 508Hz
Final answer:
The original frequency of the violin was 508 Hz. This is based on the principle of beats, where the beat frequency is the absolute difference in frequency between the two sources - in this case, the tuning fork and the violin string.
Explanation:
The original frequency of the violin string can be found using the principle of beats. The frequency of the beats is equal to the absolute difference in frequency between the two sources - in this case, the tuning fork and the violin string.
Initially, the beat frequency was heard as 4 Hz. This indicates that the original frequency of the violin was either 512 Hz + 4 Hz = 516 Hz, or 512 Hz - 4 Hz = 508 Hz. However, when the violin string was tightened, the beat frequency decreased to 2 Hz, which means the frequency of the note it was producing increased.
Therefore, the violin must have initially been producing a note with lower frequency (508 Hz), and even after tightening the string, the note it now produces (510 Hz) remains lower than that of the tuning fork.
