I think the correct answer would be the third option. The criteria that could help Linda in classifying whether the gases are greenhouse gases would be gas molecules having at least one oxygen atom. Most of the greenhouse gases has an oxygen atom in their structures especially those that naturally occurs. These gases are CO2, H2O vapor and nitrous oxide.
<span>The mechanical advantage to simple machines is that they allow a decreased input force to create a larger output force.

Answer:
Explanation:
The relation between time period of moon in the orbit around a planet can be given by the following relation .
T² = 4 π² R³ / GM
G is gravitational constant , M is mass of the planet , R is radius of the orbit and T is time period of the moon .
Substituting the values in the equation
(.3189 x 24 x 60 x 60 s)² = 4 x 3.14² x ( 9380 x 10³)³ / (6.67 x 10⁻¹¹ x M)
759.167 x 10⁶ = 8.25 x 10²⁰ x 39.43 / (6.67 x 10⁻¹¹ x M )
M = .06424 x 10²⁵
= 6.4 x 10²³ kg .
Answer:
d. 1.69 * 10^6 N
Explanation:
Pressure is defined as force divided by area.
Answer:
4.4721m
Explanation:
#Use Pythagorean theorem to find the distance between the two speakers:
There are antinodes 1/4,1/2 and 3/4 of the distance between speakers.
The greatest antinode is 3/4-1/4=1/2
#Distance between consecutive antinodes is:
Hence, the maximum possible wavelength of the sound waves is 4.4721m
