Angela is designing a wind-up toy that uses elastic bands. She conducts an experiment to find which iype of rubber band to use in her design. Her results show that the thicker and longer rubber band would move the toy the farthest. She concludes that thicker and forger rubber bands should be included in her design. Which is true about her conclusion?

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
