Answer:
Explanation:
Total resistance of 2 bulb in series
= 100 +100 = 200 ohm
current in each bulb
= 9/200 = .045 A
In case of parallel combination of bulb
total resistance
= 100 x 100 / (100+100)
50 ohm
current in the main circuit
= 9 / 50 A
current in each bulb
= 9 / (2 x 50)
.09
So in the second case current is more , hence heat generated too will be more . So brightness too will be more.
First set ( in series ) will be dimmer.
The reaction of the half-life is a description of the needed time for the reactant to deplete.In the first order reactions formula, k is considered as the first order rate constant whose unit is denoted as 1/s. Hope this helps.
Answer:
Explanation:
first ball rolls on the porch by total distance
Then again it will move on horizontal floor
also in vertical direction it will drop down
so we have

Answer:
Hypothesis:
When a scientist see lizard behaving in this way in each rainystrom in the desert, he can make a hypothesis about the lizard’s way of drinking water. He can say that lizard spread its legs to wide body. In this way it catches and carry water in microscopic channels on its body. These channels lead water to its mouth and it drinks this water by opening and closing mouth continuously.
