Answer:
Explanation:
Given
Radius of A is twice of B i.e.
Also Potential of both sphere is same
thus
(b)Ratio of
Electric Field is given by
thus ----1
----2
Divide 2 by 1
Answer:
b. A voltage causes electric charges to move from lower to a higher potential.
Explanation:
As we know, current flows from high voltage to low voltage and the electric charge flows opposite to the direction of the current. That is why we can say that the electric charge flows from low voltage to high voltage.
Resistance does not cause the electron to flow from low voltage to high voltage.
Therefore the answer is b.
Answer:
c. Solar eclipses would be much more frequent.
Explanation:
The <u>ecliptic plane</u> is the apparent orbit that the sun describes around the earth (although it is the earth that orbits the sun), is the path the sun follows in earth's sky.
A <u>solar eclipse</u> occurs when the moon gets between the earth and the sun, so a shadow is cast on the earth because the light from the sun is blocked.
The reason why solar eclipses are not very frequent is because the moon's orbital plane is not in the same plane as the orbit of the earth around the sun, but rather that it is somewhat inclined with respect to it.
So <u>if both orbits were aligned, the moon would interpose between the sun and the earth more frequently, producing more solar eclipses.</u>
So, if the moon's orbital plane were exacly the same as the ecliptic plane solar eclipses would be more frequent.
the answer is: c.
When a charged balloon is brought near a conducting can, the electrons are pushed to the far side of the can. If another object touches the side of the can opposite the balloon, electrons flow into the other object, leaving the can positively charged
