Question

The solar constant of earth is 2 cal/min-c m to the power of 2 end exponent. If distance of mercury planet from sun is 0.4 times the distance of earth from the sun, then solar constant of mercury planet will be:

  1. 12.5 c a l divided by m i n minus c m to the power of 2 end exponent    
  2. 25 c a l divided by m i n minus c m to the power of 2 end exponent    
  3. 0.32 c a l divided by m i n minus c m to the power of 2 end exponent    
  4. 2 c a l divided by m i n minus c m to the power of 2 end exponent    

The correct answer is: 25 c a l divided by m i n minus c m to the power of 2 end exponent

A pan balance has a container of water with an overflow spout on the right-hand pan as shown. It is full of water right up to the overflow spout. A container on the left-hand pan is positioned to catch any water that overflows. The entire apparatus is adjusted so that it’s balanced. A brass weight on the end of a string is then lowered into the water, but not allowed to rest on the bottom of the container. What happens next?
