A9.0-v battery is connected to a resistor so that there is a 0.50-a current through the resistor. for how long should the battery be connected in order to do 160 j of work while separating charges? express your answer to two significant figures and include the appropriate units.

35.6 s

Explanation:

The power through the resistor is given by:

where V=9.0 V is the voltage and I=0.50 A is the current. Substituting into the formula, we find

The power is also equal to:

where W is the work done while t is the time taken. Since we know the work done, W=160 J, we can re-arrange the equation to find the time taken:

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
