Answers:(a) μT
(b) μm
(c) f =
Explanation:Given electric field(in y direction) equation:
(a) The amplitude of electric field is
. Hence
The amplitude of magnetic field oscillations is
Where c = speed of light
Therefore,
μT (Where T is in seconds--signifies the oscillations)
(b) To find the wavelength use:
μm
(c) Since c = fλ
=> f = c/λ
Now plug-in the values
f = (3*10^8)/(0.4488*10^-6)
f =
Answer:
The specific latent heat of a substance is the amount of energy required to change the state of one kilo of the substance without change in it temperature.The latent heat of vaporization or evaporation is the heat given to some mass to convert if from the liquid to the vapor phase.

Answer:
Using the RC discharge and recharge table it means that after 5 time constant s there is a maximum current of 99.3% and a maximum voltage of 0.7% while form the charge table there will be a maximum voltage of 99.3% and maximum voltage of 0.7% in the RC CIRCUIT USIng
Vc/Vs= e^ -t/z for discharge and
Vc/Vs = e^(1-t/z) for charging
Answer:
The final velocity, , is gd.
Explanation:
The condition here is a free falling object. Thus from the third equation of motion under free fall, we have;
= + 2gs
where is the final velocity of the object, is the initial velocity of the object, g is the gravitational force and s is the height.
Since the object falls from a height of d, then = 0 m/s, and s = d.
So that;
= 0 + 2gd
= 2gd
= 2gd
When the distance is , = 0 m/s.
Then;
= 2g
= g x d
When the object falls through the height , then the final velocity is gd.
