We are given the total volume of liquid equal to 3392.92 cubic inches and a total of 30 glass spheres to be poured in. In this case, we divide the volume by 30 equal to 113.0973 cubic inches. The formula of the volume of a sphere is 4/3 pi r^3. r then is equal to 3 inches in which the diameter should be 6 inches.
Answer:
As the atomic number is equal to number of protons in an atom , so the atom having 15 electons has atomic number 15.
Explanation:
The body releases endorphins
Answer:
light in the UV range.
Explanation:
Noble gases and halogens can combine to form lasers called Excimer, for this to happen the noble gas must be ionized with a high voltage discharge, thus forming a molecule of the type
noble gas (X) + halogen (H) → XH
This molecule is highly unstable and decomposes within a few nanoseconds, emitting light in the UV range.
Answer:
B
Explanation:
<em>A. His speed is 0 m/s
</em>
<em>B. His velocity is 12 m/s
</em>
<em>C. His velocity is 0 m/s
</em>
<em>D. His acceleration is 12 m/s</em>
Total distance traveled by John = 120 + 120 = 240 meters
Total time taken by John to cover the distance = 10 + 10 = 20 s
<em>Average speed of John = total distance traveled/total time taken</em>
= 240/20 = 12 m/s
Hence, the average speed/velocity of John throughout the journey is 12 m/s.
The correct option is B.
