Answer:
21.18 L
Explanation:
From the question given above, the following data were obtained:
Initial pressure (P₁) = 1 atm
Initial volume (V₁) = 18 L
Final pressure (P₂) = 0.85 atm
Final Volume (V₂) =?
With the application of the Boyle's law equation, we can obtain the final volume (i.e the new volume) of the gas as follow:
P₁V₁ = P₂V₂
1 × 18 = 0.85 × V₂
18 = 0.85 × V₂
Divide both side by 0.85
V₂ = 18 / 0.85
V₂ = 21.18 L
Therefore, the new volume of the gas will be 21.18 L

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
When one body(sun) exerts a force on a second body(planet), the second body simultaneously exerts a force equal in magnitude and opposite in direction of the first body. Which makes the planet orbit in path C.
Hope this helps!!
Physics is explicitly involved in studying <span>the motion of a spacecraft under gravitational influence. Thus the answer is C.
Physic focuses more on the measurement, gravity, distances, acceleration and motion. THough all the choices are sciences but the C. is the topic that physics is involved.</span>
