Answer: heat flows from the hot water to cold water
Explanation:
Heat transfer is taken place from higher temperature to lower temperature then hot water gives heat to the cold water. There are three methods of conduction , Those are Conduction , Convection and Radiation here the heat transfer is taken place from convection.
It is about 100oC at a pressure of 1.1 atmosphere. Hope this helps.
Answer
When the light goes from one medium to another medium with higher refractive index the velocity of the ray decreases, wavelength of the ray also decreases.
But the frequency of the ray when it enters the medium of higher refractive index remain same.
So, we can conclude that speed of ray and wavelength decrease but frequency remain unchanged.
ANSWER:
D
EXPLANTION:
Every one the these option can make the magnetic field increase.
FUN FACT:
Magnetic resonance imaging machines use magnets, and they generate stronger fields than the Earth
I hoped this helped and have a great day :3
