Answer:
7.24 Ω
Explanation:
Power = energy / time = 195 J / 9.81 = 19.88 W
and power = V² / R
R resistance = 12 V² / 19.88 W = 7.24 Ω
Answer:
1st: Radiation
2nd: Conduction
3rd: Convection
Explanation:
I actually learned this before in school. Yay
In my opinion biology is the most interesting because it helps you understand why the thing around us are the way and help us survive.
Answer:
The statements that best compares radiation and conduction are the following: both transfer thermal energy from warm objects to cooler objects and both can transfer energy through matter. The difference is that conduction is through direct heat transfer; whereas, radiation transfers heat through waves.
