We know, density = mass /volume
Here, m = 10 g
v = 2.5 mL = 2.5 cm³
Substitute their values,
density = 10/2.5
<span>d = 4 g/cm³
</span>
In short, Your Answer would be <span>4 g/cm³</span>
Hope this helps!

Answer:
Adsorption
Explanation:
Sidewalk cooking of egg is very popular in America. In summer people release fireworks in night sky and cook egg on the concrete sidewalk to check the level of temperature. When sunlight fall on the sidewalk most of the light is reflected back but some darker material adsorbs some photon, and when these photons are transferred to egg molecules it causes vibration among them and produce heat and cook egg.
<span>Work, very simply, equals force times distance (when the force and distance are in the same direction. otherwise you get a little bit of trig added on) \[W=F*\Delta x\] W=70N * 9.0 m = 630 Nm = 630 J</span>
