The peak intensity of radiation from star beta is 350 nm. in what spectral band is this? uv, radio waves, visible light, or infared radiation

UV (Ultraviolet Waves)

Explanation:

As we know that wavelength range of visible light is given as 450 nm to 750 nm.

so here as we move towards higher wavelength range then the energy of electromagnetic waves will decrease as we know it is given as

now on increasing wavelength we will shifted to infrared waves while on decreasing the wavelength energy of electromagnetic waves will increase and this will shift towards ultraviolet waves

Since the given wavelength is less than the wavelength of visible light so here it is Ultraviolet Waves

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
