Question 3 of 10 - /10 8 : View Policies Part 1 Current Attempt in Progress * Your answer is incorrect. What is the speed of an electron whose total energy is equal to the total energy of a deuteron that is at rest? (Enter your answer to at least 8 significant figures. Use the following values as necessary: Melectron = 9.10938215 x 10-31 kg, Mdeuteron = 3.34358348 x 10-27 kg, and c = 2.99792458 x 108 m/s.) What is the mass of this nucleus? mass = i 1.1146e-26 kg Part 1 Hint Assistance Used (a) speed = i m/s At this speed, gamma is larger than 1.
