Answer:
(a) 62.69 nJ/m^3
(b) 1015.22 μJ/m^3
Explanation:
Electric field, E = 119 V/m
Magnetic field, B = 5.050 x 10^-5 T
(a) Energy density of electric field =
= 6.269 x 10^-8 J/m^3 = 62.69 nJ/m^3
(b) energy density of magnetic field =
= 1.01522 x 10^-3 J/m^3 = 1015.22 μJ/m^3

Explanation:
The diameter of the Moon is 3474 km. The distance across the United States, from Florida to Washington, is 4509.382 km.
Answer:
B) 3.50 m/s
Explanation:
The linear velocity in a circular motion is defined as:
The angular frequency () is defined as 2π times the frequency and r is the radius, that is, the distance from the center of the circular motion.
Replacing (2) in (1):
We have to convert the frequency to Hz:
Finally, we calculate how fast is the child moving:
