Q=l^2 times R times t
Where Q - heat, I -current, R - resistance and t is time
If you increase I twice (and it's squared), than Q gonna went up 4 times (2 squared).
Choose last
First recall the equation that relates frequency to wavelength:
v = fw
Note that the v is the speed of light, a constant. Now plug in the information we know!
(3×10^8) = (6.67 × 10^14) w
Hit the numbers on the calculator and you'll get the wavelength, w. If you comment your answer I'll check it for you. :)
Complete Question
A parallel plate capacitor contains a positively charged plate on the left, and a negatively charged plate on the right. An electron in between the plates is moving to the right. Which statement is true?
Group of answer choices
a The potential energy of the electron is decreasing and it is moving to a region having a higher potential
b The potential energy of the electron is decreasing and it is moving to a region having a lower potential.
c The potential energy of the electron is increasing and it is moving to a region having a lower potential
d The potential energy of the electron is increasing and it is moving to a region having a higher potential.
Answer:
The correct option is C
Explanation:
From the question we are told that
An electron in between the plates is moving to the right
Generally the potential energy of the electron is mathematically represented as
Here e is the charge on the electron and V is the electric potential of the electron
Generally the left side with the positive charge has a higher potential than the right side with the negative charge
Now when the potential energy of the electron increases it will move toward the plate with the lower potential which is the left plate
The answer is 8 meters per second 8m/s because 200 divided by 25 is 8
C because you can't control the sun moving across the sky and therefore is not testable in an experiment.
