Answer:
1.Sulfur dioxide and nitrogen oxide
2.a)it forms carbonic acid
b)
3.the community can use renewable energy like solar and wind power cause they produce less pollution
Thank you for posting your question here. I hope my answer will help. below are the choices that can be found elsewhere:
a. 300 mi/hr2
<span>b. 61 mi/hr2 </span>
<span>c. 8,201 mi/hr2 </span>
<span>d. 40,500 mi/hr
</span>
Below is the solution:
<span>135 * 135 / 0.450 = 40,500 mi/hr2 </span>
The metals are found on the bottom left of the table, while the nonmetals are found at the top right. These elements are separated by a 'band' of semimetals
Answer:
gravitational potential energy
Explanation:
a. You can rule out kinetic energy because it is a different type (the energy of motion).
<u>b. this is correct, because it is the energy that depends on an objects place on the gravitational field. As you can imagine, an object resting at a high place could be moved by gravity if it has the chance to fall.</u>
c. I am assuming you meant elastic, and that can be ruled out because while that is potential energy, it is dependent upon being stretched (for example a rubber band holds elastic energy when stretched).
d. mechanical energy is the sum of both kinetic and potential energy, and the question specifically asks about potential energy.
Answer:
float
Explanation:
density= mass/ volume (kg/m^3)
1.59 kg/0.197 m^3
=8.07 kg/m^3
density of H2O= 1000 kg/m3
since density(block)<density(H2O), the block will float
(can also be done in g/cm^3)
1590 g/ (1.97*10^5 cm3)= 0.00807 g/cm^3 < 1 g/cm^3 (h2O)
