Average velocity = (length and direction of displacement) / (time for the displacement).
Displacement = 5 m north
Time = 10 s
Average velocity = (5 m north/(10 s)
Average velocity = 0.5 m/s north
Answer:
pumpkins 2 and 3 will hit the target. i did the math
Explanation:
To calculate the frequency change of a moving source, the formula used is:
f = c*fo/(c+Vs)
where:
f = frequency observed
c = speed of sound
Vs = speed of source (positive if it's moving away from observer and negative if it is moving towards the observer)
fo = emitted frequency of the source
f = 342*652/(342-5)
f = 661.67 Hz or 662 Hz --> FINAL ANSWER
Explanation:
Because combining primary colors od light like red, blue, and green created secondary colors like yellow, cyan, and magenta
