BRAINLIESTTT HELP A student performs an experiment using a calorimeter to determine the specific heat of an unknown substance. The student adds 50.0 grams of water at 20
°C to the calorimeter and then adds the unknown substance. The student records that the final temperature of the system is 26 °C. Given that the specific
heat of water is 4.18 J/g•°C, calculate how much energy, in joules, the unknown substance lost

they are both synthetic elements

explanation:

d

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
