PLEASE HELP ME

Ipatiy [6.2K]

Answer:

the time period is 22.63 years

Explanation:

The computation of the number of years taken is as follows:

According to the Keplers law

$T^2 \propto R^3$

Here T denotes the time period

And, R denotes the average distance among the sun and planet

Now let us assume for earth

R_1 & T_1 be 1 year

So, for Planet

$R_2 = 8R_1 , T_2 = ?$

Now applied Keplers law

$(\frac{T_2}{T_1})^2 \propto (\frac{R_2}{R_1})^3\\\\(T_2)^2 = (\frac{8R_1}{R_1})^3 \times 1^2\\\\(T_2)^2 = 512\\\\T_2 = 22.674$

So, the time period is 22.63 years

A charge travels from the positive terminal of a 6�-V battery, through a light bulb, and through the battery back to the positiv

kodGreya [7K]

Answer:

0 V

Explanation:

- The potential for the charge to flow through the circuit and back to the same terminal means that work-done per unit length i.e Potential difference is zero because the total work-done for the charge to complete the loop and back at the same point " Terminal "

Potential difference = 6 - 6 = 0 V
