200 N, that is if the force is balanced and the wall doesn't move
A. inelastic, since the girl moves in the same direction as the thrown ball
In order to make the athletic shoe to slide faster of a given surface you had to reduce the friction coefficient of the shoe with the surface.
One way to do that is to put some grease of the sole of the shoe, which undoubtedly would reduce the friction coefficient drastically and the shoe would slide more easily.
Also, if you make the sole smoother the shoe the friction coefficient would decrease and, again, the show would slide mor easily.
Answer:
67.1 atm
Explanation:
From Dalton's law of Partial Pressures, the total partial pressure equals the sum of the individual partial pressures.
P = P₁ + P₂ + P₃
P₁ = 38.39 atm of O₂
P₂ = 3.38 atm of He
P₃ = 25.33 atm of N₂
So, P = P₁ + P₂ + P₃ = 38.39 atm + 3.38 atm + 25.33 atm = 67.1 atm
