WHAT MAKES CURRENT FLOW IN A CIRCUIT? When a wire is connected to battery terminals, electrons flow from negative to positive. Unlike (opposite) charges attract, like (same) charges repel. Electrons have a negative charge—they are repelled from the negative and attracted to the positive.

<u>I have assumed a weight of 120 N on Earth.</u>

Answer:

<em>The object weighs 20 N on the moon</em>

Explanation:

Weight

The weight of an object depends on the mass m of the object and the acceleration of gravity g of the place they are in.

The formula to calculate the weight is:

W = m.g

If g_e is the acceleration of gravity on Earth, and g_m is the acceleration of gravity on the moon, we know:

$g_m=1/6 g_e$

Dividing by ge:

$g_m/g_e = 1/6$

An object of weight We=120 N on planet Earth has a mass of:

$m = 120 / g_e$

Multiplying by gm:

$m.g_m=120 g_m/g_e$

Substituting the ratio of accelerations of gravity:

$m.g_m=120 * 1/6$

Since m.gm is the weight on the Moon Wm:

$W_m=20~N$

The object weighs 20 N on the moon

irga5000 [103]

The sum of all resistances in the series circuit is known as Equivalent resistance.

$R=r_1+r_2+.\ldots.r_n$

where R is the equivalent resistance.

Hence, option 1 is the correct answer.
