Answer:
Resistivity = 231.481 K Ohm
Yes, Intrinsic Silicon is the semiconductor.
Explanation:
Solution:
At 300K:
Let suppose mobility of electron in intrinsic semiconductor =
Mobility of electron in intrinsic semiconductor is:
= 1300
/volt.sec
Let suppose mobility of hole in intrinsic semiconductor =
= 500
/volt.sec
We know that, intrinsic silicon semiconductor has equal number of holes and electrons. So,
At 300 K
Intrinsic Carrier Concentration = 1.5 x /
= C
And,
Conductivity of intrinsic Silicon is:
σ = C x ( +
) e
e = 1.6 x C
So, plugging in the values, we get:
σ = C x ( +
) e
σ = 1.5 x x (500 + 1300) x 1.6 x
σ = 4.32 x
So, now we can find the resistivity.
Resistivity = 1/σ
Resistivity = 1/ 4.32 x
Resistivity = 231.481 K Ohm
Yes, Intrinsic Silicon is the semiconductor.

Answer:
0.958 m
Explanation:
So the total mass of the system is
M = 1.93 + 2.95 + 2.41 + 3.99 = 11.28 kg
let y be the distance from the center of mass to the origin. With the reference to the origin then we have the following equation
So the center of mass is 0.958 m from the origin
