Your answer is 392.28 newtons on earth
Answer with Explanation:
We are given that
Density=
A(4m,2m,4m) and B(0,0,0)
y=1 m
a. Linear charge density=
Let a point P (0,1,4) on the line of charge and point Q (0,1,0)
Therefore,
Distance AP=
Distance,BQ=
Electric field for infinitely long line
Therefore, potential
b.Electric field at point B
Unit vector r=
Therefore,
There is not a time when the terminal voltage would exceed the emf. option A
<h3>What is the terminal voltage?</h3>
The terminal voltage is the voltage across the external circuit. We know that the emf is the voltage when current is not being delivered to the external circuit.
Now, we know that as current continue to be supplied to the external circuit the emf continues to drop. But it should be now that there is not a time when the terminal voltage would exceed the emf.

Answer:
3: High and low tides
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Additionally, they are caused by the cycle of rising and falling ocean water that are repeated approximately every 12.5 hours.
In conclusion, the gravitational pull of the Moon is responsible for visible changes on the surface of Earth. Thus, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.
In optics, chromatic aberration (abbreviated CA; also called chromatic distortion and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.[1] It occurs because lenses have different refractive indices for different wavelengths of light. The refractive index of transparent materials decreases with increasing wavelength in degrees unique to each.
