Answer:
Explanation:
Given
When we drop an object from height , suppose h
it takes time T
using equation of motion

where




here
because it dropped from a certain height


When height is increases to three times of original height
i.e. 
then time period becomes


Answer:
there is the increase the temperature of cold body and decrease the temperature of hot body
It would be 12,000 because newton’s third 2nd law states F=ma (force=matter x acceleration) so 30x400 would be your force .
