An object in motion changes position
Answer:
Magnetic flux, 
Explanation:
It is given that,
Magnitude of the magnetic field, B = 0.078 T
Radius of circular loop, r = 0.1 m
The field is oriented at an angle of θ = 25° with respect to the normal to the surface. The magnetic flux through the surface is given by :
or
So, the magnitude of magnetic flux through the surface is 
. Hence, this is the required solution.
Because the acceleration of gravity is the acceleration of gravity.
It doesn't matter what the mass of a falling object is, and it doesn't
matter whether a falling object is solid or liquid. ALL falling objects
fall with the same acceleration, reach the same speed, and hit the
ground at the same time.
If there was no air in the way, then a feather, a school bus, and a
battleship would accelerate at the same rate, fall together and hit
the ground at the same time.
When you drop a cup full of water that has holes in it, the cup and
the water fall with the same acceleration, reach the same speed,
and hit the floor at the same time. Then, THAT's the time to go
and get the mop.
One big application is the manufacture and use of mirrors.
There are an estimated 100 billion, so the answer would be D.) Billions
