The Ecliptic is an imaginary line on the sky that marks the annual path of the sun. It is the projection of Earths orbit onto the celestial sphere. The ecliptic is even the starting point for the celestial coordinate system used by astronomers to pinpoint the location of every star, nebula, and galaxy.

Answer:
10. Stacey
11. 7.86 g/cm^3 (3dp)
OR 786 kg/m^3 (SI units)
Explanation:
10. The correct exact answer for 10 is 26.169 (6.71x3.9). While Sam was correct in the precision of the number (2dp just like the given measurements), he was incorrect in the number itself. While Stacy's number was not as precise as Sam's (0dp), it is correctly rounded to the nearest whole number, therefore Stacy is correct.
11. The formula for density is mass/volume. The mass here is 264g and the volume is 33.6ml, therefore the density is 7.86 (3 sig figs because given values had 3) g/cm^3, because the mass was given in grams and 1ml = 1cm^3. Converted to SI units it is 786 kg/m^3.
Hope this helped!
I think the best answer from the choices listed above is option C. With this accident, both should be alert and do what should be done. <span> Lee should tell the teacher while Celia washes her arm with soap and water. Doing this, Celia will prevent the chemical to spread more and harm further. Telling the teacher immediately will also alert the in-charge and do what should be done.</span>
