Time taken by the body to move through a distance of 12 m is 2 s
Explanation:
using the equation for force
m= mass= 1 kg
F= force= 6 N
a= acceleration=
6= 1 a
a= 6 m/s²
Now using the kinematic equation,
d= distance= 12 m
V= initial velocity=0 as the object is at rest initially
12= 0(t)+ 1/2 (6) t²
t²=4
t= 2 s
Weak nuclear force is weaker than the strong nuclear force with a smaller range than the electromagnetic force.
It acts between fermions with spin 1/2 basically quarks and leptons. It has a range of 10⁻¹⁸ meters.
Option 1 is incorrect. It is stronger than the gravitational force.
Option 2 is incorrect. It is weaker than the electromagnetic force.
Option 3 is incorrect. It has a smaller range than the strong nuclear force.
Yes. The main cause of polarization is by an external electric field. Polarization is characterized by an imbalance of charges where one end is more positive than the other end. When an electric field distorts the charges, there is a shift between the negative and positive poles. This causes the phenomenon called polarization.
