X-rays differ from the light source readout in terms of the intensity and the possible damage that can be obtained from the two radiation types. The light source readout is more damaging than the X-rays readout in the gizmo. Therefore, precaution is required when handling the light source readout in the gizmo.
Answer:

Answer:
Physical=Ripping
Chemical=Burning
Explanation:
I may be wrong. But I would say these are the answers.
Ans: pH = 9
<u>Given:</u>
Concentration of H+ ions [H+] = 1.0*10⁻⁹ M
<u>To determine:</u>
The pH of the above solution
<u>Explanation:</u>
pH = -log[H+]
pH = -log(1.0*10⁻⁹) = 9
Answer:
Energy produced by the chip =10,460 Joules.
Explanation:
The specific heat of water is one calorie/gram ° C = 4.186 joules/gram ° C, which is higher than any other common substance. As a result, water plays a very important role in regulating temperature. The specific heat per gram for water is much greater than that of a metal, as described in the water-metal example. Replace the mass (m), the temperature change (ΔT), and the specific heat (c) of the solution in the equation Q = c x m x ΔT, where Q is the heat absorbed by the solution. For specific heat of water we goes as given in the question 4,184 J/kg°C
Q =4184×0.5×(25-20)
=10,460 Joules.
Thus heat gained by water (Q)= Energy produced by the chip =10,460 Joules.
