Thanks! I thought that that was the correct answer, but every time I entered .54m into the homework, the system told me that I need more digits. I tried 0.540m and that finally worked for me.
An object which is 0.54m tall is located 1.23m in front of a plane mirror.
How tall is the image as seen in the mirror?
I know that the image seems to be 1.23m from the surface of the mirror and that the object seems to be 2.460m from the image.
What equation do I need to use to figure...
If a black body is heated to a temperature T (in degrees K), the most intense radiation is at a wavelength lambda (in m), where λ·T = 2.9×10−3m*K. If the burner on your electric stove is at a temperature of 683K (really hot and glowing), find the wavelength of the most intense black body...
