C. The basic unit of inheritance
Answer:
8 KJ/ s
Explanation:
Heat pumps Transfer thermal energy through absorbing of heat that comes from cold region and then release to warmer area by utilizing external power.
The coefficient of performance known as COP provide the ratio of both heating and cooling that are supplied to required work.
✓QH=The rate at which heat is produced = ?
✓COP= Coefficient of performance of a residential heat pump = 1.6
✓ W(in)= power consumption= 5KW
QH=The rate at which heat is produced=[Coefficient of performance of a residential heat pump] × [power consumption]
= 1.6 × 5KW
=8 KJ/ s
Answer:
1029 Jkg⁻¹
Explanation:
= height dropped by the water falling = 105 m
= acceleration due to gravity = 9.8 ms⁻²
= mass of water
Using conservation of energy, the internal energy produced is same as the gravitational potential energy lost, hence
Internal energy = Gravitational potential energy
