Answer:
The potential difference between the plates is 8 V.
Explanation:
Given that,
Area of plates = 0.40 m²
Charge 
Distance = 4.0 cm
We need to calculate the electric field
Using for formula of electric field
Where, q = charge
A = area
Put the value into the formula
We need to calculate the potential difference between the plates
Using formula of potential difference
Where, E = electric field
d = distance
Put the value into the formula
Hence, The potential difference between the plates is 8 V.
<u>The correct answer is 580.
</u>The upward force the right tension cord exerts on the traffic light is equal to about 114.35 N. Because the stoplight is being help upright the natural force (upward force) provided by both tension cords must be equal to the gravitational (downward) force of the traffic light which is 331.
If 114 is the upward force on the right side then 216 N must be the force provided by the left side.
You then have a right triangle with the length opposite theta = about 216 and theta = 22. So sin(22)* X = 216, where X is the length of the hypotenuse, or the force found in the left cord.
with sig figs added to the mix the answer is 580 N
I believe the answer is true to the E dgenuity physics course

Answer:
Nebulae contribute more to stellar formation than other regions because:
Explanation:
A.They have an unlimited supply of hydrogen.
B. They are believed to be rich in hydrogen and helium.
C. They have a three strong gravitational pull.
This are the reasons that Nebulae contribute more to stellar formation than other regions.
<span>The time it takes for one wavelength to pass a fixed point is known as PERIOD.
In fact, the period is defined as the time it takes a wave to make one complete oscillation: since the wavelength is the distance between two consecutive points of the wave with same shape, it means that the time it takes for one wavelength to pass a fixed point in space is exactly the period.</span>
