6 meters is left because you subtract 12 meters from 6
Net force = (mass) · (acceleration)
= (69 kg) · (29 m/s²)
= (69 · 29) · (kg·m/s²)
= 2,001 Newtons upward
(about 450 pounds)
Answer:
91 m
Explanation:
v₀ = 2.5 m/s
a = 4.2 m/s²
t = 6.0 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (2.5 m/s) (6.0 s) + ½ (4.2 m/s²) (6.0 s)²
Δx = 90.6 m
Rounded to the nearest whole number, the distance traveled is 91 m.
Nitrogen gas has a molar mass of about 28.0134 g/mol. Then we have a starting amount of
(42 g) / (28.0134 g/mol) ≈ 1.4993 mol
of N₂.
At standard temperature and pressure, one mole of an ideal gas occupies a volume of about 22.4 L. Then 42 g, or 1.4993 mol, of N₂ takes up
(1.4993 mol) × (22.4 L/mol) ≈ 33.6 L
It is letter b which is Global Warming
