Answer: Negative acceleration
Explanation:
According to the described situation we have two velocities:
-An initial velocity during the first hour:
-A final velocity during the last 200 miles:
As we can see, the final velocity is less than the initial velocity, this means the plane's velocity decreased.
On the other hand, acceleration is defined as <u>the variation of velocity in time:</u>
Since the plane's velocity decreases, the acceleration is negative.
Hence, this situation is an example of negative acceleration.
A series of smaller spots are spaced out on either side of the pattern's central, larger spot.
<h3>What is a helium-neon laser used for?</h3>
When compared to other gas lasers, helium xenon lasers are inexpensive and straightforward to operate. They have a long history of employment in numerous industries, including holography, biomedical engineering, metrology, spectrometry, optical disc reading, barcode scanning, and microscopy.
<h3>How does the helium-neon laser operate?</h3>
By energizing Neon molecules in the atmosphere, a He-Ne laser produces light. The Neon particles decay from a higher energy state to that of an ordinary state, producing the 632.8 nm optic light that the laser emits. For the given basic research, a comprehensive determination of quantum (state) is not necessary.

Answer:
Explanation:
Let us imagine that there are three wire of length equal length having equal resistances each of 44/3 Ω
Now connect these wires in parallel to so that their equivalent resistance is R.
then
