Answer:
Electric field, E = 936.19 N/C
Explanation:
It is given that,
Charge 1, 
Charge 2, 
Distance between them, d = 3 mm = 0.003 m
Torque, 
Angle between electric field and line connecting the charge, 
We need to find the torque exerted on the dipole. The torque experienced by the dipole in the electric field is given by :
p is the dipole moment, 
E = 936.19 N/C
So, the magnitude of electric field on the dipole is 936.19 N/C. Hence, this is the required solution.
Answer:
a) 40 V
b) 69.23 V
c) 69.23 V
Explanation:
See attachment for solution
You do it by the pressure difference it causes in the medium. Even in transversal waves, you usually need different units than meters because the wave has electric and magnetic vectors and not really any height to speak of.
you measure the amount of excursion from the equilibrium (no wave) level of whatever parameter is fluctuating.
5.5 s
Explanation:
The time it takes for the ball to reach its maximum height can be calculated using
since 
at the top of its trajectory. Plugging in the numbers,
