Question

An analytical laboratory balance typically measures mass to the nearest 0.1 mg. You may want to reference (Page) Section 21.6 while completing this problem. Part A What energy change would accompany the loss of 0.1 mg in mass

Answer 1

Answer:

The  energy change is  $E = 9.0 *10^{9}\ J$

Explanation:

   From the question we are told that

          Mass loss  is  $m_l = 0.1 \ mg = 0.1 *10^{-3} mkg = 0.1 *10^{-6} \ kg$

  Generally the energy change that  would accompany this loss  is mathematically represented as

     $E = m * c^2$

Where  c is the speed of light with values $c = 3.0*10^{8} \ m/s$

     $E = 0.1 *10^{-6} * [3.0 *10^{8}]^2$

     $E = 9.0 *10^{9}\ J$
