It Irregularly Reverses. I got the answer right on the test.
Answer:

Explanation:
Here at thermal equilibrium we can say that thermal energy given by Hot coffee is equal to the thermal energy absorbed by ice cubes
So here we have

now since ice cubes are added into coffee when it is at melting temperature
So here we can say that final temperature of coffee is T degree C
Now we have

here we have

L = 333 kJ/kg = 333 J/g[/tex]



now we have




Answer:
the water in the tea cup
Explanation:
Kinetic energy is the energy an object or particles possesses as a result of motion.
Liquid in higher temperature possesses more kinetic energy than liquid with lower temperature
Answer:
man will move in opposite direction with speed

Explanation:
As we know that man is lying on the friction-less surface
so here net force along the surface is zero
so if we take man + stone as a system then net change in momentum of this system will become zero
so here we have


here we have



A spring that obeys Hooke's law has a spring force constant of 272 N/m. This spring is then stretched by 28.6 cm
