Explanation:
Given that,
Frequency of the power line, f = 6 Hz
Value of maximum electric field strength of 11.6 kV/m
(a) The wavelength of this very low frequency electromagnetic wave is given by using relation as :




(b) As its can be seen that the wavelength of this wave is very high. It shows that it is a radio wave.
(c) The relation between the maximum magnetic field strength and maximum electric field strength is given by :

So, the maximum magnetic field strength is
.
Answer:3,45 x 10^9 N
Explanation: We have considered the total charge for each coin , this is the total atoms x 29 electrons for cooper and multiplier by electron charge, the total charge for each coin is 0,464 C
Finally we use the Coulomb law,
F=k Q/ (r)^2
PE= 3kg x 10N/kg x 10m
= 300J

Remember to include all data collected on warm fronts in this activity to support your answer (examples: interaction of air masses, air pressure, cloud cover, temperature behind/ahead of front, wind direction, precipitation, etc. 1
Explanation:
Answer:
Its final velocity and how much time it takes to reach the water
Explanation:
The motion of the stone is a uniformly accelerated motion, so we can use the following suvat equation to determine its final velocity:

where
v is the final velocity
u = 0 is the initial velocity
is the acceleration of gravity
s = 52 m is the distance covered during the fall
Solving for v,

We can also find how much time it takes to reach the water, using the equation

where
v = 31.9 m/s is the final velocity
u = 0 is the initial velocity
t is the time
And solving for t,
