Answer:
The average velocity that these birds travel is 122.22 miles per day to the south.
Explanation:
Speed is the physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction.
Speed is expressed mathematically as the quotient between distance and time:
where "v" is the speed of the mobile, "d" is the distance traveled by the mobile, and "t" is the time taken by the mobile to carry out the movement.
In this case:
- d= 11,000 miles
- t=3 months= 90 days (
considering that in 1 month there are 30 days)
Replacing:
velocity = 122.22 
<u><em>The average velocity that these birds travel is 122.22 miles per day to the south.</em></u>
Answer:
Explanation:
V = J/C
V = 20/1
= 20 v
Option A is the correct answer
It is an extension of the grounding system
People can break down the rock by touching or the heat can even break down the rock
The radiation detector that uses detection of flashes of light is a <u>scintillation counter.</u>
<h3>What is a scintillation counter?</h3>
A scintillation counter detects and measures ionizing radiation by using the excitation action of incoming radiation on a scintillating substance and detecting the light pulses that arise.
One of the most critical considerations for anyone who operate with or near radiation is being aware of the amounts of radiation present.
This is generally performed through the use of several types of radiation detectors.
The radiation detector that uses detection of flashes of light is a scintillation counter.
Hence,scintillation counter is the correct answer.
