Answer:
4.9 x 10⁻⁴N
Explanation:
Given parameters:
Mass of the vertical strand of spiderweb = 5 x 10⁻⁵kg
Unknown:
Tension in the vertical strand = ?
Solution:
The tension is the vertical strand will be the weight of the strand.
Weight of strand = mg
m is the mass
g is the acceleration due to gravity = 9.8m/s²
Tension in the vertical strand = 5 x 10⁻⁵kg x 9.8m/s²
Tension in the vertical strand = 4.9 x 10⁻⁴N
In sulfur dioxide, there are 2 oxygen atoms and 1 sulfur atom. As there are 32g of sulfur and 32g of oxygen, that would mean that each oxygen atom would weigh about 16g. Given that, the mass of a single sulfur atom is twice that of a single oxygen atom.
B is correct answer.
The atomic mass is the most important because it tells you the number of electrons.
Hope it helped you.

All you need to do is to convert the velocity to meters per hour. Then multiply by 0.4 hours. I guess the answer was rounded up.
Convection, because it is the process of heat transfer from one location to the next by the movement of fluids. The moving fluid carries energy within it.
