Answer:
The wave is traveling in the +x direction.
Explanation:
The equation of a wave is given by the formula as :
Here,
A is the amplitude of wave
is the phase of wave
is the angular frequency of the wave
We need to find the correct statement out of given options. The given equation can be rewritten as :
Here, the propagation constant is negative. So, the wave is moving in +x direction. Hence, the correct option is (a).
Answer:
See explanation
Explanation:
We have a mass revolving around an axis with an angular speed , the distance from the axis is . We are given:
and also the formula which states that the kinetic rotational energy of a body is:
.
Now we use the kinetic energy formula
where is the tangential velocity of the particle. Tangential velocity is related to angular velocity by:
After replacing in the previous equation we get:
now we have the following:
therefore:
then the moment of inertia will be:
It conducts electricity. This is because the electrons are able to move around more for it has gained energy, after being heated.
S.I. Unit of mass is Kilogram which is denoted by Kg
In short, Your Answer would be Option C
Hope this helps!
IM sure there is C, D, and E in kuiper belts, but not really sure of silicon and iron
