If small objects can be anything, basically anything goes! People could go, ants could go, they are really tiny, use your imagination, and you could think of many possibilities!
#1
As per kinematics we know that
here we know that
now we will have
Now by Newton's II law
#2
part a)
Impulse = change in momentum
given that
m = 0.153 kg
v = 25.7 m/s
now we have
Part b)
As per Newton's II law we know that
as we know that
Explanation:
Below is an attachment containing the solution.
Explanation:
let us use the explanation below to get the intuition so desired;
According to Faraday's law of electro magnetic induction, when ever a coil/conductor is made to rotate in a magnetic field, voltage or emf is created and current is produced, in the long run energy has be produced or converted.
The conversion of this energy is made possible by the motion of the coil/conductor is the magnetic field, just by the motion of the conductor cutting through the magnetic field, thus creating electro motive force(E.M.F) hence producing current, and ultimately energy is created
