Answer:
Explanation:
Given data
Ex = Ey = 0
Ez=(4.3V/m)cos(π×10¹⁵s⁻¹)(t-x/c)
To find
The amplitude of the magnetic field component
Solution
The electric field is given by:
Ez=(4.3V/m)cos(π×10¹⁵s⁻¹)(t-x/c)
Where Em=4.3 V/m
The magnitude of magnetic field is given by:
Where Em is amplitude of electric field and c is speed of light.
Substitute the given values
So
Answer:
89.16pounds
Explanation:
The equation that defines this problem is as follows
W=k/X^2
where
W=Weight
K=
proportionality constant
X=distance from the center of Earth
first we must find the constant of proportionality, with the first part of the problem
k=WX^2=131x3960^2=2054289600pounds x miles^2
then we use the equation to calculate the woman's weight with the new distance
W=2054289600/(4800)^2=89.16pounds
Answer:
Yes, the answer to the question is correct
Because 2 carbon attach to one's of each of the others
