The expected speed is v = 85.5 km/h v = 85.5 km/h = (85.5 km/h)*(0.2778 (m/s)/(km/h)) = 23.75 m/s
If there is an uncertainty of 2 meters in measuring the position, then within a 1-second time interval: The lower measurement for the speed is v₁ = 21.75 m/s, The upper measurement for the speed is v₂ = 25.75 m/s. The range of variation is Δv = v₂ - v₁ = 4 m/s
The uncertainty in measuring the speed is Δv/v = 4/23.75 = 0.1684 = 16.84%
The gas inside the can and the can’s volume are both constant. The gas pressure increases with increasing temperature. The can will burst if the pressure becomes great enough. The gas law that applies is Gay-Lussac’s law.
<span>Ka is the acid dissociation constant or the acidity constant. It is a measure of the acid strength when in solution. It is an equilibrium constant for the dissociation of the acid.</span>
