Answer:
True
Explanation:
Convection simply means the transfer of heat resulting from the movement of the molecules of fluid, which can be liquid or gas.
Convection can either be natural or forced. natural convection occurs by a natural means ,such as the difference in density of warm air and cool air. This occurs when the cooler air falls and the warmer air rises.
However in forced convection, the fluid is agitated by an external force eg a fan or pump.
Yes, since it depends on the normal and resultant
Answer:
Δx = 1.2 m
Explanation:
The CHANGE of spring length) (Δx) can be found using PS = ½kΔx²
Δx = √(2PS/k) = √(2(450)/650) = 1.17669... ≈ 1.2 m
The actual length of the spring is unknown as it varies with material type, construction method, extension or compression, and other variables we have no clue about.
The answer is (B 60N) hope it helps and have a good day!
Free ions. Negative ions have one extra electron, positive ions are missing an electron. Negative ions give up their extra electron easily. I hope my answer has come to your help. God bless and have a nice day ahead! Feel free to ask more questions.
