B: gravity is absent in space
Answer:
700 joules
Explanation:
potential energy = m × h × g
( m = mass, h = height, g = acceleration due to gravity )
- P.E = 14 × 5 × 10
- P.E = 700 J
hence, gravitational potential energy of the object is 700J

Thermal conduction happens fastest through a solid.
Answer:
Explanation:
As we know that here final equilibrium temperature is 0 degree C
so we can use energy conservation here
heat given by the cube = heat absorbed by the ice
so we have
so here we have
