Answer:
8.60 g/cm³
Explanation:
In the lattice structure of iron, there are two atoms per unit cell. So:
where
an and A is the atomic mass of iron.
Therefore:
This implies that:
=
Assuming that there is no phase change gives:
= 8.60 g/m³
The Earth's electric field creates a potential that increases 100 V for every meter of altitude. If an object of charge 4.5 mC a
1 answer:
Answer:
The final kinetic energy is
Explanation:
From the question we are told that
The electric field is
The charge on the object is
The mass of the object is
The distance moved by the object is
The workdone on the object by the fields is mathematically represented as
Now this workdone is equivalent to the final kinetic energy so
substituting values

answer : short period oscillations frequency = 0.063 rad / sec
phugoid oscillations natural frequency ( ) = 4.27 rad/sec
Explanation:
first we have to state the general form of the equation
=
where :
comparing the general form with the given equation
= 18.2329
hence the short period oscillation frequency ( ) = 0.063 rad/sec
phugoid oscillations natural frequency ( ) = 4.27 rad/sec
