Answer: Gravitational force and drag force
Explanation:
For a snowboard jumper in the air, two forces would be acting. One in the downward direction- the gravitational pull and second in the opposite direction to the motion, the drag force due to air. If the snowboard jumper jumps in the air at a certain angle with the horizontal. The forces are written as the sum of vertical and horizontal components. Hence, for the modeling the motion, gravitational force and drag force are important,

Explanation:
We know that the relation between volume and density is as follows.
Volume = ![\frac{\text{mass}}{\text{density}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7Bmass%7D%7D%7B%5Ctext%7Bdensity%7D%7D)
So, V = ![\frac{10^{-3}}{19.3 \times 10^{3} kg/m^{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B10%5E%7B-3%7D%7D%7B19.3%20%5Ctimes%2010%5E%7B3%7D%20kg%2Fm%5E%7B3%7D%7D)
= ![5.181 \times 10^{-8} m^{3}](https://tex.z-dn.net/?f=5.181%20%5Ctimes%2010%5E%7B-8%7D%20m%5E%7B3%7D)
Now, we will calculate the area as follows.
Area = ![\frac{\text{volume}}{\text{length}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7Bvolume%7D%7D%7B%5Ctext%7Blength%7D%7D)
= ![\frac{5.181 \times 10^{-8} m^{3}}{2.4 \times 10^{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B5.181%20%5Ctimes%2010%5E%7B-8%7D%20m%5E%7B3%7D%7D%7B2.4%20%5Ctimes%2010%5E%7B3%7D%7D)
= ![2.15 \times 10^{-11} m^{2}](https://tex.z-dn.net/?f=2.15%20%5Ctimes%2010%5E%7B-11%7D%20m%5E%7B2%7D)
Formula to calculate the resistance is as follows.
R = ![\rho \frac{l}{A}](https://tex.z-dn.net/?f=%5Crho%20%5Cfrac%7Bl%7D%7BA%7D)
= ![\frac{2.44 \times 10^{-8} \times 2400}{}2.15 \times 10^{-11}}](https://tex.z-dn.net/?f=%5Cfrac%7B2.44%20%5Ctimes%2010%5E%7B-8%7D%20%5Ctimes%202400%7D%7B%7D2.15%20%5Ctimes%2010%5E%7B-11%7D%7D)
= ![2.71 \times 10^{6} ohm](https://tex.z-dn.net/?f=2.71%20%5Ctimes%2010%5E%7B6%7D%20ohm)
Thus, we can conclude that the resistance of given wire is
.
