Answer:
Rest energy = (9.00 × 10¹³) J
Amount in dollars that can be obtained if the rest energy is entirely converted to electrical energy is $3,750,300
Step-by-step explanation:
According to Einstein's formula, rest energy (E) is given as
E = mc²
m = mass = 1 g = 0.001 kg
c = speed of light = (3.00 × 10⁸) m/s
E = 0.001 × (3.00 × 10⁸)²
E = (9.00 × 10¹³) J
Converting this energy to KWh
1 J = (2.778 × 10⁻⁷) KWh
(9.00 × 10¹³) J = (9.00 × 10¹³) × (2.778 × 10⁻⁷)
= 25,002,000 KWh.
1 kWh = 15 cents
25,002,000 KWh = 15 × 25,002,000 = 375,030,000 cents = $3,750,300
Hope this Helps!!!
