V = f(wavelength)
22.0 = 0.0680 (wavelength)
wavelength = 323.52 m
Answer:
6.0 ×
W/
Explanation:
From Wien's displacement formula;
Q = e A
Where: Q is the quantity of heat transferred, e is the emissivity of the surface, A is the area, and T is the temperature.
The emissive intensity =
= e
Given from the question that: e = 0.6 and T = 1000K, thus;
emissive intensity = 0.6 × 
= 0.6 × 1.0 × 
= 6.0 ×

Therefore, the emissive intensity coming out of the surface is 6.0 ×
W/

It is B
it is called a jumper cable because it jumps the power from one car to the other
Answer:
Iron has a higher heat capacity than copper
Explanation:
The heat capacity of a substance is defined as the amount of heat required to raise the temperature of an object by 1°C.
The higher the heat capacity of a substance, the longer the time it takes for the substance to become hot when heated.
Since the copper rod becomes too hot to hold much sooner than the iron rod, it means that iron has a higher heat capacity than copper.
