When different resistors are connected in parallel across an ideal battery, we can be certain that: a) their equivalent resistan
sergeinik [125]

Answer:

b) the potential difference across each is the same.

Explanation:

When resistors are connected in parallel with each other

then the terminals of all the resistors will connected across the terminals of the battery

So we know the potential difference of the battery is same across all the resistors

So we can say that the equivalent resistance of all the resistance is

\frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}

so its not the mean of all resistors

also we know that the resistance are all different so power across each resistance is different given as

P = \frac{V^2}{R}

also current in each resistance is also different and given by

i = \frac{V}{R}

so correct answer will be

b) the potential difference across each is the same.

: Click Play. Observe how the position of the red dot in the SIMULATION pane relates to the cycle of night and day on the 2D VIE
Korolek [52]

Answer:

rotating movement on itself, it creates the phenomenon of day and night.

Explanation:

When a body that rotates around a star (translational movement), rotates on itself (rotational movement), the light from the star cannot reach the opposite part of the object, so at these points it is NIGHT and when in the rotation movement the point is in front of the star it is DAY.

Therefore, in rotating movement on itself, it creates the phenomenon of day and night.
