Answer:
Half life of S = 3.76secs
Explanation:
The concept of half life in radioactivity is applied. Half life is the time taken for a radioactive material to decay to half of its initial size.
For part 1 - How much signal will be degraded in 1secs = 1/3.9 = 0.2564
for part 2 - How much signal will be degraded in 1secs = 1/104 = 0.009615
Simply say = 1/3.9 + 1/104 = 0.266015
So both part 1 and part 2 took 1/0.266015 = 3.76secs is the half life of S when both pathways are active
I think the correct answer from the choices listed above is option B. If asked to describe a wave, you could say waves are the continuous transmission of energy from one location to the next. <span>In physics, a </span>wave<span> is an oscillation accompanied by a transfer of energy that travels through a medium. Hope this helps.</span>
I don't know the name, but the opposite of gravity, if that helps!
Explanation:
Given that,
Two resistors 4.5 Ω and 2.3 Ω .
Potential difference = 30 V
When they are in series, the current through each resistor remains the same. First find the equivalent resistance.
R' = 4.5 + 2.3
= 6.8 Ω
Current,

So, the current through both lightbulb is the same i.e. 4.41 A.
When they are in parallel, the current divides.
Current flowing in 4.5 resistor,

Current flowing in 2.3 ohm resistor,

In parallel combination, are brighter than bulbs in series.
