Question

This version of Einstein's equation can be used directly to find what value? `Δm = E/c^2` A. the energy that is released in a nuclear reaction B. the speed of light C. the mass that is lost in a fusion reaction D. nuclear binding energy

Answer 1

Answer

c. the mass that is lost in a fusion reaction

Explanation

The  Einstein's equation E = Δm × c² is used to find the energy that is released in a nuclear reaction.

Where E is the energy released, m is the mass and c is the speed of light.

When Δm is made the subject of the formula we get:

Δm = E/c²

This represent the mass that is lost in a fusion reaction.

Answer 2

C) the mass that is lost in a fusion reaction.

See from Einstein's equation ∆m = E/c^2 we can find change in mass directly if we know the energy released or gained.

Now, nuclear fusion is a highly exothermic reaction so during the reaction a lot of energy is released. We know the speed of light.

So if we just put in the value of energy released, we get the amount of mass lost during reaction.

Hope it helps!!!
