The mass of the ion is 5.96 X 10⁻²⁵ kg
<u>Explanation:</u>
The electrical energy given to the ion Vq will be changed into kinetic energy 
As the ion moves with velocity v in a magnetic field B then the magnetic Lorentz force Bqv will be balanced by centrifugal force 
.
So,
and
Right from these eliminating v, we can derive
On substituting the value, we get:
m = 5.96 X 10⁻²⁵ kg.

Answer:
1449 K
Explanation:
The surface temperature of a star is related to its peak wavelength by Wien's displacement law:
where
T is the surface temperature
b is Wien's displacement constant
So the surface temperature of the star is
B .Newton's first law holds that your body moves along with Earth because it is not compelled to change its motion by an unbalanced force
It would do exactly what a rock or a frisbee does when you toss it.
After the engines cut off, it couldn't get any more energy from
anywhere, and after that, as it pushed air aside to get through,
and had air molecules scraping against it, those would slowly
rob kinetic energy from it. Sooner or later it would run out of
kinetic energy, start falling, and it would eventually make either
a big 'SPLOOSH' or else a big 'CRUNCH', depending on exactly
where it returned to Earth's surface.
