Answer:
10.198 g/cm³
Explanation:
ρ=m/V=123.4/12.1=10.198 g/cm³
Total hours is 3.35 hours
<u>Explanation:</u>
Given:
convert 3 hours 21 minutes to decimal hours
We know:
1 hour = 60 minutes
and
1 minute = 60 seconds
1 minute = 1 / 60 hours
So,
21 minutes = 
= 0.35 hours
Total hours would be = 3 hours + 0.35 hours
= 3.35 hours
Therefore, total hours is 3.35 hours
Answer:
that's true current is discoverd originally by benjimin franklin Followed by tesla and Edison.
Explanation:
Answer: Option (B) is the correct answer.
Explanation:
Direct current is a current which flows in one direction, that is, flow of electrons is only in one direction.
Whereas alternate current is a current which reverses periodically, that is, there will be change in direction of electrons after a period of time.
Thus, we can conclude that the statement, In DC, electrons move in only one direction. In AC, electrons move in one direction and then in the other direction defines AC and DC correctly.
H's result was one dead flower ... not surprising ... stuck in a dark room = no photosynthesis = no growth = death.
H loses is "control" part of his "experiment".
Q gives no idea the colour of H's flowers in expt.
H "shows" that a watered plant in sunlight with a bit of fetilizer tends to grow. He could have had a look outside at a garden to see that.
improvement by not killing the "control" plant. put it side by side with the test plant, so both get the photo stuff. Then measured fertilizer in test plant, and same water minus fert in control.
As for the colour I've no idea.
