Question

When the plutonium bomb was tested in New Mexico in 1945, approximately 1 gram of matter was converted into energy. Suppose another bomb is tested, and 4.9 grams of matter are converted into energy. How many joules of energy are released by the explosion

Answer 1

Answer:

4.404*10 ¹⁴ J

Explanation:

Plutonium bomb are employed in making nuclear fission bombs. So,

Given that:

approximately 1 gram of matter was converted into energy when tested in New Mexico.

Another bomb is tested which contains:

a mass of the plutonium = 4.9 grams

To calculate the number of joules of energy are released by the explosion; we have:

energy = mass * speed of light²

speed of light = 299792458 m/s

So. Energy = 4.9 × 10⁻³ ( 299792458)²

Energy = 4.404*10 ¹⁴ J
