The mass of a moving object increases, but its speed stays the same. What happens to the kinetic energy of the object as a resul
2 answers:
The correct answer is
B It increases.
In fact, the kinetic energy of a moving object is given by
where m is the mass of the object and v is its speed. We see that the kinetic energy is proportional to the mass and proportional to the square of the speed: in this problem, the speed of the object remains the same, while its mass increases, therefore the kinetic energy will increase as well.

Explanation:
The area of the circular loop is given by:
The magnetic flux is given by:
is parallel to
and
is constant in magnitude and direction therefore:
Part A)
initially the flux is
after the interval
the flux is
now, the EMF is defined as:
,
if we consider very small then we can re-write it as:
then:
Part B)
When looked down from above, the current flows counter clockwise, according to the right hand rule, if you place your thumb upwards (the direction of the magnetic field) and close your fingers, then the current will flow in the direction of your fingers.
