Answer with Explanation:
We are given that
Charge on alpha particle=q=2 e=
1 e=
Mass of alpha particle=m=
Potential difference,V=
Magnetic field,B=3.49 T
a.Speed of alpha particle=v=
By using the formula
b.Magnetic force,F
F=
c.Radius of circular path, r=
r=0.084 m
The answer is Homeostasis
the input force is either by hand or electric power. The output force is the the metal at the top of the can being removed and the movement around the can opener
1 km/hr = 1000/3600 m/s = 5/18 m/s
time taken = 5 x 18/5 sec = 18 sec
