Answer 2

Answer:

The ratio of 3MJ Energy and 2ns is $1.5\times 10^{15} W$.

Explanation:

Here,

The work is denoted by W.

The time is denoted by t.

Now,

By the formula,

$P=\frac{w}{t}$

Joule(J) per second(s) is equal to Watt(W).

$\frac{J}{S}=W$

Then,

Then according to the question,

The ratio of 3MJ Energy and 2ns = $\frac{3MJ}{2ns}$

                                                       = $\frac{3\times 10^{6}J }{2\times10^{-9}S }$

                                                       = $1.5\times 10^{15} \frac{J}{S}$                  ∴ $\frac{J}{S}=W$

                                                       = $1.5\times 10^{15} W$

So, the ratio of 3MJ Energy and 2ns is  $1.5\times 10^{15} W$.
