Answer:
magnetic field = - 6.137 × T
Explanation:
given data
radio wave λ = 0.3 m
intensity I = 45 W/m²
time t = 0
time t = 1.5 ns
to find out
What is Bz
solution
we use here equation of intensity of radiation of electric field that is express as
intensity = .................1
here we know intensity 45 and c is 3 × m/s² and ∈o is 8.85 × C²/N.m² and E will be here
E = ...............2
E =
E = 184.15
and
E = .................3
184.15 =
= 6.137 × T
and in z axis magnetic field will be here as
B = ..............4
here k =
k = = 20.94
and
f =
f = =
so here
time t =
t = =
so ω =
ω =
ω = 6.28 ×
so now from equation 4
B =
B =
B = - 6.137 ×
so magnetic field = - 6.137 × T
Answer:
C: bulimia-nervosa
Step-by-step explanation:
This eating disorder is categorized by binge eating and then purging.
Yes. Because as you travel further away from the surface of earth your mass stays the same however your weight decreases as the gravitational pull decreases also.
