Answer:
The correct option is B
Explanation:
Active galaxies are characterized by a small core of emission at the center which is usually brighter than the rest of the galaxy. The energy emitted from active galaxy is way more than that emitted from normal galaxy. As compared to normal galaxy where it's energy emission is thought to be the sum of the emission from each star found in the galaxy, this is not true or the same in active galaxy. <u>There (active galaxy) huge energy emission cannot be explained as the sum of the emission of their stars</u>.
1.)bounced off...in pretty sure(sorry if wrong)
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
The answer is B.)
This is because for years scientists have build up and found discoveries that led to recent discoveries brought by previous scientists.
Hope this helps
Potential Energy: It is the energy that is associated with the relative position of a body within a force field.
Kinetic Energy: It is the energy that a body contains due to its state of movement.
Thermal Energy: is associated with the sum of the microscopic kinetic and potential energies of the system.
Total Energy: it is the sum of all the energies that a body contains.
