The molar mass and molecular weight of LiNO3 is 68.946.
This depends on whether the pipe is closed or open ended.
The fundamental frequency of a pipe is the simplest, smallest portion of a wave that can fit into a pipe. At the open end of a pipe, there is always an antinode - an area with maximum air movement.
If it is an open ended pipe, there is an antinode at each end, meaning that the length of the pipe is equal to 1/2 <span>λ
</span>. Manipulating the formula <span><span>v=fλ</span>
</span> to solve for the fundamental frequency leaves us with <span><span>f=<span>v/<span>2L</span></span></span>
</span> in an open ended pipe.
the answer would be C
work done = force * distance
wd = 3*2
wd = 6 J
wd = 2*3
wd = 6 J
so the work done is the same
Answer:
* If it is an incandescent lamp, the increase in temperature of the towel could set it on fire,
* If the towel is wet, there could be a short circuit
Explanation:
Covering the lamp with a towel has several problems:
* If it is an incandescent lamp, the increase in temperature of the towel could set it on fire, which could be a danger
* If the lamp is not incandescent, the temperature rise of the towel is not very high,
* If the towel is wet, there could be a short circuit due to the humidity of the lamp with the wet towel
* If the towel is wet when touched, there could be a shock towards the person due to the electrical conduction
Consequently, covering the bulb with a towel is a serious mistake.
