Answer:
679.08 lbs
Explanation:
Here it is given that
= Mass of first person = 175 pounds
= Height of first person = 70 inches
= Mass of second person
= Height of second person = 110 inches
The weight of the second person would be 679.08 lbs
1). <u>Power = (voltage)² / (Resistance)</u>
4,500 = (220)² / Resistance
Multiply each side by (resistance) : 4,500 x resistance = (220)²
Divide each side by 4,500 : Resistance = (220)² / 4,500 = <em>10.76 ohms</em>
2). <u>Power = (voltage) x (Current)</u>
Divide each side by (voltage): Power / voltage = Current
4,500 / 220 = <em>20.45 Amperes</em>
3). 4,500 watts = 4.5 kilowatts
(4.5 kilowatts) x (4 hours) = <em>18 kilowatt-hours</em>
The height risen by the hammer when the work were done is 10 m.
The given parameters;
- <em>Mass of the hammer, m = 8.0 kg</em>
- <em>Work done on the hammer, W = 780 J</em>
<em />
Apply work energy - theorem to determine the height risen by the hammer when the work is done on it;
Thus, the height risen by the hammer when the work were done is 10 m.

I believe it would be 127.8 pounds. weight = mass x gravity
Answer:
b
Explanation:
in this condition the atom is not stable so in order to become stable ( trying to have the last energy level completely filled like the Nobel gases) it tends to lose or gain or share the electrons and that debend on its condition . I hope that's the right answer
