Ascientist observed a 5-ml sample of an unknown substance. it is a blue liquid with a density of 1.2 g/cm. the substance reacts with carbon dioxide. lust each of the properties the scientist observed and whether it is a characteristic property of matter.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
