lisabon 2012 [21]

Answer:

45.13 beats/min

Explanation:

Speed of space vehicle  = 0.51c

the pulse rate measured by the astronaut= 61.0 beats per minute

Pulse rate measured by the Earth observer is given by

=(pulse\ rate)\sqrt{1-\frac{v^2}{c^2} }

putting vales we get

=61\sqrt{1-\frac{0.51^2c^2}{c^2} }

= 45.13 beats/min
