In a given lightning flash, the potential difference between a cloud and the ground is 2.86 times 109 V and the quantity of char

ge transferred is 23.1 C. What is the decrease in energy of the transferred charge? (Please give the magnitude.) If all that energy could be used to accelerate a 1519 kg automobile from rest, what would be the final speed of the automobile?

Answer:

Explanation:

decrease in energy of the transferred charge

= Voltage x charge

= 2.86 x 10⁹ x 23.1

= 66.067 x 10⁹ J

the final speed of the automobile be V

1/2 m v² = 66.067 x 10⁹

v² = 66.067 x 10⁹ x 2 / 1519

= .08698 x10⁹

= 87 x 10⁶

v = 9.32 x 10³ m / s

Kisachek [45]
If I were to go from the United States to China in one second, that's a large distance in an incredibly short time. I'd say that's pretty fast.

If I were to go from my room to the door of my room in a year, then that would be unbearably slow.

Answer:

i hope it will be useful for you

Explanation:

F=5.6×10^-10N

R=93cm=0.93m

let take m1 and m2 =m²

according to newton's law of universal gravitation

F=m1m2/r²

F=m²/r²

now we have to find masses

F×r²=m²

5.6×10^10N×0.93m=m²

5.208×10^-9=m²

taking square root on b.s

√5.208×10^-9=√m²

so the two masses are m1=7.2×10^-5

and m2=7.2×10^-5
