You don't need to worry about the 10 year bit with this question. Just grab a calculator and divide 100/2, then the answer to that (50) by 2 etc and keep dividing by 2 until you get down to 6.25.
The answer ends up being 4 half lives :)
If you don't understand what a half life is please let me know :)
Answer:
Properties of semiconductors are determined by the energy gap between valence and conduction bands. To understand, what is semiconductor, we have to define these terms. In solid-state physics, the energy gap or the band gap is an energy range between valence band and conduction band where electron states are forbidden.
My answer -
I believe that the answer is (A).
P.S
Happy to help you have an AWESOME!! day
I think jogging/running/walking because you don't need any equipment and you can structure around it on your own time.
To solve this problem we will apply the concepts of the Magnetic Force. This expression will be expressed in both the vector and the scalar ways. Through this second we can directly use the presented values and replace them to obtain the value of the magnitude. Mathematically this can be described as,
Here,
q = Charge
v = Velocity
B = Magnetic field
Our values are given as,
Replacing,
Therefore the size of the magnetic force acting on the bumble bee is
