about the sun.
Answer in units of rad/s.
The damage threshold for the retina is 100 W/m2. This means that a damage to the retina can occur at an average intensity greater than this. The light coming from a 5.0 mW green laser has a diameter of 1.2 mm. (a) Will this laser exceed the damage threshold for the retina? (b) What are the maximum values of the electric and magnetic fields of the beam coming from this laser?

3.Mention 2 effector organs that process so that the body could return to a set point?
When body temperature drops, the hypothalamus initiates several physiological responses to increase heat production and conserve heat: Narrowing of surface blood vessels (vasoconstriction) decreases the flow of heat to the skin; shivering commences, increasing production of heat by the muscles; Adrenal glands secrete stimulatory hormones such as norepinephrine and epinephrine to increase metabolic rates and hence heat production. These effects cause body temperature to increase. When it returns to normal, the hypothalamus is no longer stimulated, and these effects cease.
