Answer:
The intrinsic carrier density of diamond is .
Explanation:
Given that,
Energy band gape = 5.4 eV
Temperature = 300 K
We need to calculate the intrinsic carrier density of diamond
Using formula of density
....(I)
We need to calculate
Put the value into the formula
We need to calculate
So.
Now, Put the value of and in equation (I)
Hence, The intrinsic carrier density of diamond is .
^they’re correct! it is weathering, i just took a test with that answer:)
Answer:
The constant force is 263.55 newtons
Explanation:
There's a rotational version of the Newton's second law that relates the net torque on an object with its angular acceleration by the equation:
(1)
with τ the net torque and α the angular acceleration. It’s interesting to note the similarity of that equation with the well-known equation F=ma. I that is the moment of inertia is like m in the linear case. The magnitude of a torque is defined as
with F the force applied in some point, r the distance of the point respect the axis rotation and θ the angle between the force and the radial vector that points toward the point the force is applied, in our case θ=90 and sinθ=1, then (1):
(2)
Because the applied force is constant the angular acceleration is constant too, and for constant angular acceleration we have that it's equal to the change of angular velocity over a period of time:
It's important to work in radian units so knowing that
(3)
The moment of inertia of a disk is:
(4)
with M the mass of the disk and R its radius, then
using the values (3) and (4) on (2)
(2)
Because the force is applied about the rim of the disk r=R=1.50:
<span>Displacement is the difference between the initial position and the FINAL position of an object.

Hey
Say that there was no light on in the building that they were ch,at,tin,g in, then they could hear each other but not see each other.
