Answer:
they're more inclined to be violent so A
Answer:

Explanation:
It is given that,
A planar electromagnetic wave is propagating in the +x direction.The electric field at a certain point is, E = 0.082 V/m
We need to find the magnetic vector of the wave at the point P at that instant.
The relation between electric field and magnetic field is given by :

c is speed of light
B is magnetic field

So, the magnetic vector at point P at that instant is
.
Answer:

Explanation:
As we know that the angular acceleration of the wheel due to friction is constant
so we can use kinematics

so we have



now time required to completely stop the wheel is given as



now time required to stop the wheel is given as
