In Einstein's special theory of relativity, mass and energy are equivalent. An expression of this equivalence can be made in terms of electron volts ( units of energy) and kilograms, with one electron volt (eV) being equal to 1.78*10^ -36 kg. Using this ratio, express the mass of the heaviest mammal on earth, the blue whale, which has an average mass of 1.90*10^ 5 kg , in mega electron volts and tera electron volts

In MeV: 10.674 × 10^(34) MeV

In TeV: 10.674 × 10^(28) TeV

Explanation:

We are given that;

1.78 × 10^(-36) kg = 1 eV

We are now told that the blue whale has an average mass of 1.90 × 10^(5) kg

Thus, converting this mass of the blue whale to eV, we have;

(1.90 × 10^(5) × 1)/(1.78 × 10^(-36)) = 10.674 × 10^(40) eV

Now, converting to mega electron volts;

From conversions;

1 eV = 10^(-6) MeV

Thus,

10.674 × 10^(40) eV will be;

(10.674 × 10^(40) × 10^(-6))/1 = 10.674 × 10^(34) MeV

Also, converting to Tera electron Volts;

From conversion, we know that;

1 eV = 10^(-12) TeV

Thus;

10.674 × 10^(40) eV will give;

(10.674 × 10^(40) × 10^(-12))/1 = 10.674 × 10^(28) TeV
