Question

An astronaut accidentally gets separated out of his small spaceship accelerating in inter-stellar space at a constant acceleration of 10 m/S to the power of 2 end exponent . What is the acceleration of the astronaut at the instant he is outside the spaceship ?

  1. 10 m/S to the power of 2 end exponent    
  2. 9.8 m/S to the power of 2 end exponent    
  3. 0 m/S to the power of 2 end exponent    
  4. could be anything    

The correct answer is: 0 m/S to the power of 2 end exponent


    When the astronaut is outside the spaceship, the net external force (except negligible gravitational force due to spaceship) is zero as he is isolated from all interactions.

    A semiconductor P-N junction is to be forward biased with a battery of e.m.f. 1.5 Volt. If a potential difference of 0.5V appears on the junction which does not depend on current and on passing 10mA current through the junction there occurs huge Joule loss, then to use the junction at 5mA current, the resistance required to be connected in its series will be:
